Le Trias du Jura, de la Bresse, de la plaine de la Saone et de la bordure nord du Massif Central (note preliminaire)
Authors: Ricour Jean , Horon O. , Lienhardt G.
Published: March 2020

Deep borings in the Saone and Bresse plains, France, show that the Triassic section of the western Jura mountains thins rapidly westward. All zones within the section exhibit a reduction in thickness. Triassic sedimentation is considered to have occurred in a gulf south of the emergent Morvan massif, which is believed to have reached the northern border region of the Central Massif. West of La Chatre certain variegated clays attributed to the Triassic are Liassic deposits instead.
Monnieria dans le Tithonique recifal de l'est des Cordilleres betiques
Authors: Astre Gaston
Published: March 2020

Specimens of small diceratids from Tithonian (Jurassic) reef deposits of the eastern Betic cordilleras belong to Monnieria or a closely related genus. Their presence suggests analogous reef environments during the Portlandian and Tithonian in southern Spain and the Languedoc region, southern France.
Sur la tectonique de la zone subbetique de la region de Huescar (prov. de Grenade, Espagne) et sur son Nummulitique
Authors: Foucault Alain
Published: March 2020

Defines structural units of the Subbetic zone north of Huescar, Spain. In order of probable superposition, these include, from bottom to top, the Virgen de la Cabeza unit (Dogger, Malm, lower Cretaceous), the Barranco de la Cueva del Agua unit (lower Liassic to Dogger), and the Moncayo-La Sagra unit (lower Liassic). The exact position of the Marmolance unit, with lower Priabonian (Jurassic) deposits at the base and upper Oligocene deposits at the top, is not known; at least it is known to be superposed on the Virgen de la Cabeza unit.
Micropoudingues et gres a galets mous du Westphalien C du bassin houiller du Nord-Pas-de-Calais
Authors: Dolle Pierre
Published: March 2020

Systematic sampling of the base of all beds of sandstone encountered in recent deep borings in the Nord-Pas-de-Calais coal basin, France, leads to some remarks concerning the correlation of the sandy sediments in the Westphalian C (Carboniferous). Sandstones with siderite pebbles are distinguished from the microconglomerates of ordinary sandstones. These terms are defined and explained.
Ramification d'une tige principale de Lyginopteris oldhamia Binney
Authors: Louvel Christiane

Relations spatiales entre les pegmatites et les granites en Afrique centrale et a Madagascar
Authors: Varlamoff Nicolas
Published: March 2020

The spatial relationships of pegmatites and granites of central Africa and Madagascar are briefly described. Two groups of pegmatites are distinguished. The pegmatites of one group are directly related to the granite massifs and are arranged in fairly well-defined sequences of different types around the contacts. Those of the other occur at greater depth and are related to processes of gneiss formation, migmatization, and regional granitization. The two groups are very different in genesis and mode of emplacement.
Polypiers senoniens des environs de Padern (Aude)
Authors: Beauvais Marcel
Published: March 2020

Describes a new genus and species of coral from Senonian (Cretaceous) sandy and glauconitic limestones north of Padern in Aude, France--Elasmosmilia padernensis. The upper Santonian age of the limestones is established by the presence of Phyllosmilia complanata.
Les granites precambriens a Madagascar
Authors: Delbos Leon
Published: March 2020

The Precambrian granites of Madagascar are classified into three groups on the basis of mode of formation, petrographic and chemical composition, and age. The first group consists of the stratoid granites scattered over the whole island; these are often rich in allanite, and have been dated as 550 X 10 6 years old. The second group comprises the Ambatofinandrahana-Vavavato complex, an ancient metamorphosed massif having an apparent age of 1,100 X 10 6 years. The Ambatomiranty granites, characterized by a less common facies than other granites of the island, have the same apparent age. The third group is represented by the Anosyen granites. They are the product of alkaline metasomatism of plagioclasic rocks, accompanied by formation of abundant charnockites. Granitization is considered to have occurred in different stages, of which the most important is dated as 900 X 10 6 years, corresponding with the period of charnockite formation.
Etude geologique de la zone forestiere de la Joux, au nord-est de Champagnole (Jura)
Authors: Weber Christian
Published: March 2020

New data resulting from regional reconnaissance in the Joux forest zone northeast of Champagnole, France, are presented. They relate principally to details of the Jurassic stratigraphy, which has been clarified on the basis of horizons exhibiting distinctive microfacies. Interpretation of the tectonics was facilitated by a structure map contoured on the top of the Kimeridgian.
Sur la structure de la region d'Akjoujt (Mauritanie)
Authors: Destombes Jean Paul , Spindler J. P.
Published: March 2020

The Cambro-Ordovician age of the Akjoujt series in Mauritania is confirmed. It differs in composition from the equivalent pelitic-sandy series immediately to the east (Iriji). Its present form, an apparently thick synclinal series, is due to repetition in isoclinal recumbent folds and thrust slices of low dip that can be explained by gravitative gliding at the time of orogenic uplift. This structure is similar to that of areas to the south, in contrast to the less deformed structure of contemporaneous strata to the east. The folding may have occurred in the Caledonian. The geomorphology of the hills surrounding Akjoujt is explained by early burial in a deep graben of the entire folded series after the principal orogeny, and subsequent, relatively recent rejuvenation.
Sur la presence de galets eoliens dans le complexe de base de l'Adrar mauritanien
Authors: Bongrand Marie Odile , Dars R. , Sougy J.
Published: March 2020

Wind-faceted pebbles found at the base of the sandy Infracambrian formations of the Adrar region of Mauritania confirm the existence of Infracambrian desert conditions (paleoregs) and suggest the possibility of a new unconformity in the lower part of the basal complex capping the basement.
Decouverte de dents de palaeomastodontes dans la region de Zella (Tripolitaine)

Sur les phenomenes de recristallisation dans la serie metamorphique du mont Pilat (Massif central); albitisation et retromorphose
Authors: Chenevoy Maurice
Published: March 2020

Analysis of the metamorphism of rocks of the Pilat massif and elsewhere in the Central Massif region, France, results in recognition of three types of metamorphic reconstitution-- textural rearrangement of primary minerals, development of instability of primary minerals without obliteration of the original mineralogic composition of the rock (retrograde metamorphism in its strict sense), and recrystallization. Albitization observed at various horizons is considered due to topochemical recrystallization rather than to introduction of soda by hydrothermal solutions.
Contribution de la sedimentologie a la stratigraphie de l'Eocene inferieur dans le sud-est du Bassin parisien
Authors: Michel Jean Pierre
Published: March 2020

Paleogeography of the southeastern part of the Paris basin during the lower and middle Eocene (Sparnacian-Ypresian-Lutetian) is revealed by X-ray sedimentologic study of sedimentary formations in the Chatillon-sur-Morin quarry near Esternay. Kaolinitic clays with small amounts of Sparnacian detrital materials represent deposition in lakes or lagoons. Attapulgite, indicating a regressive episode, occurs in the upper Sparnacian at Sezanne. The Cuisian (Ypresian) is made up of sandstones and kaolinitic clays overlain by marl becoming progressively more limy, and ending with siliceous limestone of the Sahara hamada type. The surface of the siliceous limestone is covered by attapulgite indicating a final regressive episode following progressive drying of the climate as revealed by increase in the amount of attapulgite upward in the Cuisian. The Lutetian (middle Eocene) is transgressive, with kaolinitic marl grading upward into freshwater limestone.
Sur l'origine des flyschs et des nappes de la Lucanie meridionale (Italie)
Authors: Glangeaud Louis , Grandjacquet Claude , Bousquet Jean Claude , Afchain Claude
Published: March 2020

In southern Lucania, from the Agri river south to Cetraro and the southwestern shore of the gulf of Tarento, and particularly near the Tyrrhenian (western) coast of Lucania, flysch of undetermined age and complex relationships is a major part of both autochthonous and allochthonous tectonic units. The fundamental problem is the paleogeography of different allochthonous flysch sequences of Mesozoic and Tertiary age. The second is the geographic origin of the flysch and the dolomitic limestone. Third is the mechanism and time of emplacement of nappes. The nappes of dolomitic limestones and the Cetraro gneiss plates behaved tectonically as rigid elements, quite differently from the plastic nappes of the allochthonous flysch. The fourth great problem is differentiating Mesozoic allochthonous flysch from that of Miocene-Pliocene age. Some of the allochthonous flysch may have come from the Tyrrhenian basin to the west.
Etude du Lutetien inferieur de Saint-Leu-d'Esserent (Oise)
Authors: Blondeau A. , Cavelier Claude
Published: March 2020

Stratigraphic, paleontologic and sedimentologic study of an escarpment on the right bank of the Oise river at Saint-Leu-d'Esserent, France, permits the division of the lower Lutetian beds into three zones corresponding to R. Abrard's zones I, II, and III. Zone I is characterized by Nummulites lamarcki and Lenita patellaris. It consists of coarse sands representing tumultuous sedimentation and limestones with a constant fauna indicating calm depositional conditions. The microfauna is similar to the Aizy Cuisian but the frequencies are different--Miliolidae do not exist in zone I. The zone I-II passage is progressive, marked only by the appearance of Nummulites laevigatus, the decrease in N. lamarcki and the disappearance of Lenita patellaris. The two zones seem to belong to the same group--lower Lutetian. The zone II-III boundary is clear, corresponding to a major change in bathymetry, the seas having become quite shallow. Zone III is characterized by the disappearance of glauconite and N. laevigatus and by the rapid increase of the Miliolidae and Orbitolites complanatus. These facts suggest that part of Abrard's zone IV--basal upper Lutetian--is also present. The granulometry and heavy mineral content of the beds are presented in tabular form. A complete list of the microfauna is given.
Les terrasses quaternaires des Andes venezueliennes
Authors: Tricart Jean , Millies-Lacroix Adrien
Published: March 2020

The extensive terrace deposits of the Venezuelan Andes reach a maximum thickness of 200 meters. They are widespread on the piedmont areas and in the interior longitudinal and transverse valleys. The oldest terrace--Pliocene-Villafranchian--is contemporaneous with the tectonic force which produced the Andean arch. The three younger terraces were deposited during the uplift of the Andes and the accompanying subsidence of the surrounding land. These deformations explain the staggering of the terrace levels which reach an altitude of 500 meters above the recent thalwegs. The terrace deposits are primarily the product of reworked latosols deposited before the uplift of the Maracaibo horst. The youngest terrace represents a transition between the second and third terraces and the recent alluvium. The alternating periods of erosion and deposition are the result of climatic oscillations. The three most recent alluvial covers (Quaternary) are the result of the blocking of the major valleys by mudflows and landslides interrupted periodically by cyclones and accompanying diluvial rains. Results of granulometric and petrographic analyses of the deposits are presented in tabular form.
Profils geologiques en Calabre sud-occidentale
Authors: Dubois Roland
Published: March 2020

The geology of southwestern Calabria (Italy) presents certain problems that are yet to be resolved. A zone of isolated dolomite outcrops is only a convenient term to relate rocks of similar lithology but does not imply paleogeographic continuity. Triassic and Paleocene fossils have been found in the dolomites but there is no evidence of continuous sedimentation and dolomitization may have contributed the appearance of continuity to the zone. A larger quartzitic schist zone extends from the Sila mountain to the Tyrrhenian coast. These thick beds are composed of sericite schist with quartz pebbles aligned parallel to planes of schistosity. Fossils have not been found but the zone is believed to be an allochthon or a para-autochthon related to the Hercynian sedimentary cycle. East of Sila a metamorphosed zone of crystophylline gneiss, crossed by granite veins, abruptly replaces the schists.
Introduction a l'etude du Quaternaire de la region de Teheran
Authors: Motamed Ahmad
Published: March 2020

At the foot of the Elbourz chain, in the vicinity of Teheran, is an irregular alluvial plain on which three phases of deposition can be observed. The Pliocene-Pleistocene formation, in the northern part of the plain is composed of poorly cemented conglomerates grading in the central area to a limonite formation. The lower Quaternary consists of alternating coarse and fine beds. The Quaternary of the highlands shows a zone of limey accumulation overlain by a clay and iron-rich zone from which the lime has been washed.
Donnees stratigraphiques nouvelles apportees par les bryozoaires sur le Miocene du bassin molassique de Rumilly (Haute-Savoie)

The bryozoan fauna from two exposures of the marine molassic deposits of the Rumilly basin confirms the lower Helvetian-Vindobonian age of the upper series of deposits and the Burdigalian age of the lower series.
Nature et origine des eaux de Barbotan, Dax et Cauterets (Aquitaine)
Authors: Schoeffler Jacques , Coustau H. , Sourisse C.
Published: March 2020

Due to numerous data from petroleum exploration in Aquitaine, new hypotheses are advanced concerning certain thermal springs: Barbotan seems to issue from an aquifer in sands below molassic deposits; Dax flows from an upper Cretaceous aquifer; the Cauterets waters are iodine-rich as are the granites from which they flow.

The glyptodonts of the Pleistocene of Tarija in southern Bolivia are little known. Only the genus Glyptodon has been described. New studies, in the field and in collections, establish the presence of five genera: Glyptodon, Chlamydotherium, Neothoracophorus, Hoplophorus, and Panochthus. Panochthus cf. tuberculatus and Hoplophorus echazui n. sp. are described in detail.
Observations preliminaires sur le comportement du lithium dans les roches d'epanchement d'Auvergne
Authors: Letolle Rene
Published: March 2020

Spectrometric analyses, using the isotopic dilution method, were performed on 20 samples from the Mont-Dore volcanic series (France). The procedure used is a modified version of the Smales and Webster method. Two series of values were obtained for the lithium content, one exceeding 50 ppm in the Permo-Carboniferous lavas, the other, 5-20 ppm for the basaltic lavas. No correlation is apparent between the percent of lithium and that of other alkalic elements although their chemical properties are similar. A correlation does exist, however, between the percent of lithium and silica. Lithium is preferentially incorporated in the magnesian minerals when the percent of magnesium diminishes in the residual magma.
Les laves acides de la cote orientale de Madagascar
Authors: Jeremine Elisabeth , Lenoble Andre
Published: March 2020

The upper pre-Senonian acidic lavas which form volcanic massifs in the Vohemar region rest directly on the crystalline basement and are considered the product of surface fissure flows. In the Nosy-Varika area these lavas can be divided into two major groups--rhyolites and dacites. The rhyolitic lavas are the most alkalic, the lightest-colored and the least calcic of all the rocks studied. They include alkalic rhyolites, rhyolites with plagioclase, and dellenites. The dacites contain andesine and labradorite. Sakalavites are also reported from the area and may represent the last phase of acidic emissions, possibly a transitional stage passing into the later basaltic lavas.
Observations sur la fenetre antecambrienne de la Snodola et sur la region septentrionale du 'Fjell' de Ringebu (Norvege)
Authors: Prost Andre
Published: March 2020

The region studied is situated between Gudbrandsdal and OOesterdal, in the northwest part of the sparagmite formation. The Precambrian is exposed in a fenster southwest of the Atna Archean fenster. The sequence of beds in this area differs from the Eocambrian of the type area and is barren of fossils. The units seem to be autochthonous or parautochthonous on the Precambrian, formed at the expense of the Archean. The repetition of sparagmite and dark schist at the top of the sequence suggests the presence of a nappe structure although the origin and extent of the folding is not evident.
Existence de deux phases periglaciaires, separees par un haut niveau marin, en Vendee
Authors: Ters M.
Published: March 2020

Two periglacial phases can be recognized on the Vendee coast of France, at Bretignolles. The first phase is represented by a sand-clay matrix in which are included microgranite blocks transported by mudflows from the Saint-Martin-de-Brem massif. Under the flow, the micaschist of the basement complex is locally disaggregated and forms a polygonal soil. These features are preserved by the sand and gravel deposits of the Tyrrhenian II transgression which depressed the shores and bays of the Vendee and Loire coasts of the Atlantic. The later periglacial phase produced garland tongues, V-shaped pockets, and frost cracks in the Tyrrhenian shore deposits.
Les mineraux lourds des terrasses quaternaires de Limagne d'Auvergne et les eruptions montdoriennes
Authors: Rudel Aime
Published: March 2020

Heavy mineral analysis of the Villafranchian Couzes valley alluvium, Chambon lake tuffs, and the basal alluvial sands of the Perrier formation reveals the presence of acicular augite. The mineral is also present in the volcanic sands at Arnats and the upper terraces at Limagne. The presence of augite in this form is linked to the volcanic activity of Mont-Dore. The augite was wind dispersed during the eruptions, to locations far from the craters. Its presence in the ancient Quaternary terraces and the Villafranchian tuffs and alluvium implies the existence of Mont-Dore eruptions of the same age.

A bibliography of his publications is given.
Etude geologique de la region de Barcis (Alpes meridionales, province d'Udine, Italie)
Authors: Saint-Marc Pierre
Published: March 2020

Triassic to middle Miocene rocks make up the Venetian Prealps sequence in the Barcis region (Udine province, Italy). The thick sediments belong to the eastern border of the Friuli zone. Shallow water limestones deposited from the Liassic through the Dogger were succeeded by reef limestones from the Malm to Cretaceous. The limestones are covered by Eocene flysch. ESE to WNW ripple marks and a later occurrence for the flysch on the west side of the area indicate an eastern source for the flysch deposits. Miocene sediments contain glauconite and littoral fauna. Major tectonics in the area are believed to be post-Miocene.
Les eclogites et leurs transformations au milieu des gneiss du massif de Snieznik dans les Sudetes
Authors: Smulikowski Kazimierz
Published: March 2020

The Snieznik eclogites of Poland are intercalated with a migmatitic gneiss and form a lithologic series differentiated by the ratio of omphacite to carinthine. They range from the common eclogites without primary amphibole to rocks rich in carinthine. The latter cannot be designated as a true eclogite for they contain no omphacite and should be placed above the sequence. Several successive stages of amphibolitization are apparent. They are the individualization of a purer common secondary hornblende and of an acidic plagioclase, ending in ordinary amphiboles. These rocks were then affected by a potassium-type metasomatism on a regional scale which was responsible for the granitization and migmatization of the surrounding gneiss and culminated the metamorphic evolution of the lithologic unit.
Le Pliocene et les accidents periglaciaires de la plage de la Mine d'Or a Penestin (Morbihan)
Authors: Riviere A. , Vernhet S. , Arbey F. , Desprairies Alain
Published: March 2020

Detailed study of the cliffs along the Mine d'Or coast provides results which indicate that two Pliocene stratigraphic sequences are separated by a period of emergence or semi-emergence locally evidenced by a slight unconformity and the presence of a ferruginous layer at certain points. Examination of the evidence of tectonic deformation confirms the existence of slight recent activity. Quaternary frost action, in areas where the arenaceous basement rock has been replaced by a white plastic clay, produced cryoturbation phenomena analogous to Recent pingos of the polar regions. Their morphology indicates that there were two successive glacial phases. The ferruginous crust observed at the base of and between the two Pliocene sequences is formed today in the present climate and under geologic conditions similar to those which existed during the Pliocene.
Observations nouvelles sur la stratigraphie du Jurassique de la region de Kandreho (Madagascar)
Authors: Blaison Jean
Published: March 2020

The cuestas along the Ikahavo coast, north of Tsilanarano, are designated as the type section for the Madagascar Jurassic. The transgressive marine Toarcian overlies the Isalo sandstone unconformably and is more extensive than previously thought. The thickness of the Aalenian is decreased due to the increased importance of the Toarcian. The Bathonian was located more to the north at Beranonorambe. Three ammonite species are described, Phymatoceras collignoni n. sp. (middle Toarcian), Sonninia (Sherbonites) aff. adicra, and Micromphalites (?) sp. (middle-upper Bathonian). Astarte baueri n. sp. is described from the Bouleiceras-Protogrammoceras zone.
Interpretation d'une succession interessant la limite oligo-miocene dans le sud du Bordelais
Authors: Caralp Michelle , Moyes Jean , Puechmaille Chantal , Vigneaux Michel
Published: March 2020

A core drilled at Salles, southwest of Bordeaux (France), yielded a section of strata which embraces the Oligocene-Miocene boundary. The beds are principally limestones with a predominance of carbonates in opposition to small amounts of detrital elements. On the basis of the frequency of the fauna included in the limestones three sedimentary zones are distinguished. The basal zone contains allochemical components suggesting calm sedimentation and includes nummulites and abundant melobesiids. The intermediate zone has faunal and lithologic characteristics of both the underlying and overlying zones. In the upper zone Miogypsinoides fades out and glauconite and pyrite appear. Examination of the foraminifera and ostracod microfaunas reveals three biozones which correspond to the sedimentary zones. Two tables give the distribution of the principal foraminifera and ostracod species. The type of sediments and the distribution of the microfaunas indicate that the basal zone is Oligocene, the upper zone is Miocene and the intermediate zone marks the top of the Oligocene.
Sur la stratigraphie et la paleogeographie du Frioul occidental: Le Val Cellina (Alpes meridionales, Udine, Italie)
Authors: Cousin Michel
Published: March 2020

The Jurassic, Cretaceous, and Eocene beds cropping out on the northern and southern flanks of the Claut syncline are compared and contrasted with the Barcis series to the south. Description of six sections reveals the dissimilarity of the facies and thicknesses between the northern and southern flank beds. From north to south the passage from reefal to pelagic sedimentation can be observed, accompanied by an increase in the thickness of the series. During the Malm a reef zone SW of Barcis was oriented SSW-NNE. Red nodular limestones, characteristic of a pelagic shoal, were deposited during the Kimmeridgian and Tithonian. The reef zone persisted throughout the lower Cretaceous depositing microbreccias on its NW flank. The reef zone is recognized in the upper Cretaceous of the Claut syncline. Terrigenous deposits of Scaglia (upper Campanian-Maestrichtian) and sandy marls (Danian-lower Paleocene) represent the subflysch of Vassoevitch. True flysch is recognized in the Paleocene and Eocene and is homogeneous throughout the Val Cellina with no positive relationship with the Malm and Cretaceous limestone series. The flysch is progressively younger from north to south.

Influence de la tectonique du Pays de Bray sur les formations paleogenes au voisinage de sa terminaison orientale
Authors: Blondeau A. , Cavelier Claude , Pomerol Charles
Published: March 2020

Major facies changes in the Paleogene formations at the southeast end of the Pays de Bray anticline of the Paris basin, in the vicinity of Beaumont-sur-Oise, date tectonic movements and periods of remission during the Paleogene. Although the anticline developed during the late Cretaceous, it seems to have had no significant effect upon sedimentation until its emergence and the concurrent establishment of continental sedimentation in the upper Thanetian (lower Eocene). Tectonic activity occurred again in the lower Sparnacian and the upper Cuisian (lower Eocene), the lower and the upper Lutetian (middle Eocene), the Ledian (lower Priabonian: upper Eocene), the Ludian (upper Priabonian: upper Eocene), and the lower Stampian (middle Oligocene).

Observations nouvelles sur le passage du Cambrien a l'Ordovicien dans la Montagne-Noire
Authors: Boyer Francois , Guiraud Rene
Published: March 2020

Recent discovery of fossiliferous horizons in the Cambro-Ordovician shale-sandstone series of Montagne-Noire in southern France indicates a stratigraphic discontinuity involving thinning or possible absence of the upper Cambrian under transgressive lower Ordovician. It is not known whether the upper Cambrian was not deposited, or was eroded prior to the Ordovician deposition.
Phases terminales et tectogenese de la montagne Sainte-Victoire
Authors: Touraine Fernand
Published: March 2020

Sainte-Victoire mountain has been considered as the eroded remnant of a massif whose first signs are known from the upper Cretaceous but which was actually emplaced during the lower Eocene. Three studies of the area have shown that the basic structure, but not the relief, was formed in the Eocene; intense erosion in the Oligocene and Miocene peneplaned the area. In a post-Tortonian phase the structure was uplifted and acquired its present morphology. The uplift is limited on the west by a fault at the foot of the Bau-Roux plateau; the eastern limit is the Delubre fault. The tectonic history of the area developed in seven phases and interphases from the upper Cretaceous to the post-Tortonian.
Observations nouvelles sur la flore de charophytes du Stampien du bassin de Paris

Published: March 2020

Seventy charophyte species, three of which are new, are described from marls associated with Etampes limestones near Fontainebleau and Soisy-sur-Ecole (Seine-et-Marne, France). Two other species are recorded for the first time from the Paris basin. The age of these beds, based on the new charophytes, is Stampian (Tertiary).
Etude sedimentologique des principaux facies du Turonien de Touraine
Authors: Riveline-Bauer Janine
Published: March 2020

Outcrops and cores in Touraine, France, have exposed lower Turonian (or Salmurian) and upper Turonian (or Angoumian) facies which contain varying amounts of detrital minerals, carbonates, and silica, the latter represented partly by opal-cristobalite. The facies include tuffs, shelly sand, spongolite, and chalk. The clay mineralogy of kaolinite in the upper Turonian chalk facies suggests an origin from a kaolinite deposit or from a mixture of montmorillonite, illite, and kaolinite. The study reveals an increase of carbonates and silica in the lower Turonian from northwest to southeast accompanied by a decrease in detrital material.
Extraction des fractions granulometriques d'un sediment par elutriation, et utilisation de ces fractions pour l'etablissement de diagrammes de distribution du calcaire

Granulometric fractions are obtained from the fine portion of loose sediment isolated in the center of the Bahco elutriator-centrifuge. The possibility of using this method for obtaining each granulometric fraction separately would permit comparison between them. These fractions can be used to plot limestone distribution as a function of the diameter of the particles.
Observations sur la mise en place du granite de Saint-Guiral-Liron (Cevennes meridionales)
Authors: Prager Michel
Published: March 2020

The Saint-Guiral-Liron granite consists of a porphyritic granodiorite intruded into folded Paleozoic schists of the Cevennes mountains to the north and the Vigan nappe area to the south. The composition of the granodiorite is homogeneous and nearly isotropic. Metamorphism at the northern border of the granodiorite resulted in the formation of gneiss, and at the southern border, of flint. The southern contact indicates extremely intense emplacement with development of an aureole of exothermal contact metamorphism. The joint systems of the northern and southern borders are described and interpreted.

In the Charolais ridge in the northeastern part of the Central Massif (France) two granites can be distinguished. The Vauzelles granite to the south, is subalkaline, medium-grained, slightly porphyritic, and poor in inclusions. The Mary granite to the north is a coarse-grained monzonitic porphyry, containing green hornblende, and rich in inclusions. Identical granophyres are associated with both granites, but in differing modes of occurrence. This is ascribed to the difference in depth of the granites, the Vauzelles being deeper. The age of the granites is Visean (Carboniferous).
Le Quaternaire de la cote libanaise compare a celui du Maroc atlantique
Authors: Gigout Marcel
Published: March 2020

The Quaternary of the Lebanese and Moroccan coasts reflects five or six transgressions. Littoral marine sedimentation is represented by rich shell deposits in Morocco, but not in Lebanon. Inland from the coasts, entrenched fluvial terraces are observed in Morocco, whereas the same areas in Lebanon are occupied by slopes whose gradients are related to the maritime plains.
Premieres observations sur les alentours de la baie de Tongoy (Chili)
Authors: Herm Dietrich , Paskoff Roland , Stiefel Joerg
Published: March 2020

The Tongoy bay area, situated 300 km north of Valparaiso (Chile), is a graben bordered by two uplifted blocks. During the Pliocene and Quaternary this graben served as a depositional trap. From a geomorphic point of view, three marine stages are recognized, corresponding to periods of stillstand above present sea level. Geomorphic, paleontologic, and sedimentologic studies permit a precise determination of the Pliocene-Quaternary evolution of this region.
Stratigraphie et paleogeographie du Cretace inferieur de l'anticlinal de Gourdan et du bassin du Var moyen de Daluis a la Mescla
Authors: Cotillon Pierre
Published: March 2020

The Var basin (Provence Alps, southeastern France) is separated from the Esteron basin to the south by the Gourdan anticline. During much of early Cretaceous time the geography of this area closely resembled the present, with two basins separated by a fault scarp at the position of the present Gourdan anticline. In the Var basin a thick Vocontian-type section of dark pelagic marls to the west graded into a neritic section of thicker Berriasian sediments, very calcareous Valanginian sediments, and glauconitic Hauterivian deposits to the east. In the Esteron basin to the south, sediments were subneritic, with numerous interruptions of sedimentation and abundant glauconite. After Bedoulian (early Aptian) time the scarp disappeared so that the basins coalesced and sedimentation became uniform.

Donnees nouvelles sur le Cretace de la haute et moyenne vallee du Tagliamento (Alpes meridionales, Frioul, Italie)
Authors: Cousin Michel , Durand Delga Michel , Sigal Jacques
Published: March 2020

From the Cretaceous of Monte San Simeone [southern Alps, Italy], where the middle and upper Cretaceous stages are known (Selli, 1963), we have investigated and more precisely defined the known Cretaceous beds and have discovered other terrains whose stratigraphic assignment is yet to be established. The data are applied to certain stratigraphic problems (dating of a break and of breccias from the lower or middle Cretaceous), different types of sedimentation are described and compared, and some paleogeographic correlations are proposed.
Styles tectoniques de l'unite de l'Aljibe au nord du detroit de Gibraltar (Espagne meridionale)
Authors: Didon Jean
Published: March 2020

Different tectonic styles are recognized within the Aljibe unit N of the Strait of Gibraltar [southern Spain]. The lithology of this unit and that of the basement are, to a large extent, the cause. An anticline of the Penibetic basement, against which the sandstone of the Numidian facies has accumulated in tight folds and shingle blocks, seems to have played a large role during the emplacement of the unit. Elsewhere, it [the Aljibe unit] was dislocated into separate layers which have been overturned, welded, or overthrust. The westward displacements have local N-S components.
Etude geologique de la region de Stenico (Alpes meridionales, province de Trente, Italie)
Authors: Charvet Jacques
Published: March 2020

Marine facies ranging in age from Liassic to Eocene are present in the Stenico region (southern Alps, Trento province, Italy). The facies represent a transition between the Trentino flexure to the east and the Lombardy depression to the west. Neritic deposits in the Liassic are succeeded by pelagic deposits; pelagic sedimentation predominated from the upper Jurassic through the lower Eocene and became neritic in the middle Eocene. Evidence from brecciated formations indicates that movement at the beginning of the upper Cretaceous caused emergence in certain sections and reworking of submarine deposits in others.
Une espece nouvelle de Metrionaxon Glinski 1963 (Tetracoralla) dans le Couvinien du Finistere
Authors: Plusquellec Yves
Published: March 2020

Three Couvinian deposits in Finistere have yielded examples of a new species of Metrionaxon, M. paucitabulatum n. sp. Both internal molds and nondecalcified specimens of this small form are described. The genus, which seems to be restricted to the middle Devonian, has been previously known only in Germany (Eifel, Bergisches Land) and in Poland (Skala Podolskaya).

Published: March 2020

Background : Several models have been developed to predict asymptomatic carotid stenosis (ACS), however these models did not pay much attention to people with lower level of stenosis (＜50% or carotid plaques, especially instable carotid plaques) who might benefit from early interventions. Here, we developed a new model to predict unstable carotid plaques through systematic screening in population with high risk of stroke.
Methods : Community residents who participated the China National Stroke Screening and Prevention Project (CNSSPP) were screened for their stroke risks. A total of 2841 individuals with high risk of stroke were enrolled in this study, 266 (9.4%) of them were found unstable carotid plaques. A total of 19 risk factors were included in this study. Subjects were randomly distributed into Derivation Set group or Validation Set group. According to their carotid ultrasonography records, subjects in derivation set group were further categorized into unstable plaque group or stable plaque group.
Results : 174 cases and 1720 cases from Derivation Set group were categorized into unstable plaque group and stable plaque group respectively. The independent risk factors for carotid unstable plaque were: male (OR 1.966, 95%CI 1.406-2.749)，older age (50-59, OR 6.012, 95%CI 1.410-25.629; 60-69, OR 13.915, 95%CI 3.381-57.267;≥70, OR 31.267, 95%CI 7.472-130.83) , married(OR 1.780, 95%CI 1.186-2.672)，LDL-C(OR 2.015, 95%CI 1.443-2.814), and HDL-C(OR 2.130, 95%CI 1.360-3.338). A predictive scoring system was generated, ranging from 0-10. The cut-off value of this predictive scoring system is 6.5. The AUC value for derivation and validation set group were 0.738 and 0.737 respectively.
Conclusions ：For those individuals with high risk of stroke, we developed a new model which could identify those who have a higher chance to have unstable carotid plaques. When an individual’s predictive model score exceeds 6.5, the probability of having carotid unstable plaques is high, and carotid ultrasonography should be conducted accordingly. This model could be helpful in the primary prevention of stroke.
Training needs for Ugandan primary care health workers in management of respiratory diseases: a cross sectional survey
Authors: Nantanda Rebecca , Kayingo Gerald , Jones Rupert , Gemert Frederik van , Kirenga Bruce
Published: March 2020

Background

Respiratory diseases are among the leading causes of morbidity and mortality in Uganda, but there is little attention and capacity for management of chronic respiratory diseases in the health programmes. This survey assessed gaps in knowledge and skills among healthcare workers in managing respiratory illnesses.

Methods

A cross sectional study was conducted among primary care health workers, specialist physicians and healthcare planners to assess gaps in knowledge and skills and, training needs in managing respiratory illnesses. The perspectives of patients with respiratory diseases were also sought. Data were collected using questionnaires, patient panel discussions and review of pre-service training curricula for clinicians and nurses. Survey Monkey was used to collect data and descriptive statistical analysis was undertaken for quantitative data, while thematic content analysis techniques were utilized to analyze qualitative data.
Results

A total of 104 respondents participated in the survey and of these, 76.9% (80/104) were primary care health workers, 16.3% (17/104) specialist clinicians and 6.7% (7/104) healthcare planners. Over 90% of the respondents indicated that more than half of the patients in their clinics presented with respiratory symptoms. More than half (52%) of the primary care health workers were not comfortable in managing chronic respiratory diseases like asthma and COPD. Only 4% of them were comfortable performing procedures like pulse oximetry, nebulization, and interpreting x-rays. Majority (75%) of the primary care health workers had received in-service training but only 4% of the sessions focused on respiratory diseases. The pre-service training curricula included a wide scope of respiratory diseases, but the actual training had not sufficiently prepared health workers to manage respiratory diseases. The patients were unsatisfied with the care in primary care and reported that they were often treated for the wrong illnesses.
Conclusions

Respiratory illnesses contribute significantly to the burden of diseases in primary care facilities in Uganda. Management of patients with respiratory diseases remains a challenge partially because of inadequate knowledge and skills of the primary care health workers. A training programme to improve the competences of health workers in respiratory medicine is highly recommended.

Published: March 2020

Background: Sexually transmissible infection (STI) and blood-borne virus (BBV) diagnoses data are a core component of the Australian National Notifiable Diseases Surveillance System (NNDSS). However, the NNDSS data alone is not enough to understand STI and BBV burden among priority population groups, like Aboriginal and Torres Strait Islander people, because it lacks testing, treatment and management data. Here, we describe the processes involved in establishing a STI and BBV sentinel surveillance network representative of Aboriginal Community-Controlled Health Services (ACCHS)—known as the ATLAS network—to augment the NNDSS and to help us understand the burden of disease due to STI and BBV among Aboriginal and Torres Strait Islander peoples.
Methods: Researchers invited participation from ACCHS in urban, regional and remote areas clustered in five clinical hubs across four Australian jurisdictions. Participation agreements were developed for each clinical hub and individual ACCHS. Deidentified electronic medical record (EMR) data relating to STI and BBV testing, treatment and management are collected passively from each ACCHS via the GRHANITE tm data extraction tool. These data are analysed centrally to inform 12 performance measures which are included in regular surveillance reports generated for each ACCHS and clinical hub.
Results: The ATLAS network currently includes 29 ACCHS. Regular reports are provided to ACCHS to assess clinical practice and drive continuous quality improvement initiatives internally. Data is also aggregated at the hub, jurisdictional and national level and will be used to inform clinical guidelines and to guide future research questions. The ATLAS infrastructure can be expanded to include other health services and potentially linked to other data sources using GRHANITE.
Conclusions: The ATLAS network is an established national surveillance network specific to Aboriginal and Torres Strait Islander peoples. The data collected through the ATLAS network augments the NNDSS and will contribute to improved STI and BBV clinical care, guidelines and policy program-planning.
