Mode de mise en place des protrusions de l'Atakor (Hoggar)
Authors: Girod Michel
Published: June 2020

The Atakor massif of the central Hoggar region of the Sahara is a complex of late Tertiary-Quaternary trachyte, phonolite, basalt, and basanite occurring chiefly as protrusions resembling eroded volcanic necks, and resting upon a basement of Suggarian (Precambrian) formations. Four types of protrusions are recognized among the nearly four hundred in the area: those with accompanying lava resting upon a bed of pyroclastics, circular or elliptical in plan; those in which the lava took the form of an oriented coulee, also resting on pyroclastics; cupola-shaped masses with some pyroclastics and little lava; and those without lava. Factors governing the form of individual protrusions include chemical composition, temperature of emission, and content of dissolved gases, as well as peculiarities of shape of the vent.

Microfaunes cenomaniennes et santoniennes dans le 'calcaire des canons' (vallee d'Aspe, Sainte-Engrace, Basses-Pyrenees)
Authors: Cuvillier Jean , Henry Jacques , Ribis Richard , Villanova Michel
Published: June 2020

The upper Cretaceous 'canyon' limestone or Hippurites limestone of the Aspe river valley in the Basses-Pyrenees of southwestern France is transgressive upon Paleozoic formations of the western part of the axial zone of the Pyrenees. The limestone is locally underlain by a thin bed of quartz conglomerate, quartzite, and shale of unknown age. The basal part of the limestone, generally sandy or conglomeratic and with local beds of dolomite, is dated as Cenomanian (basal upper Cretaceous) by the foraminifer Praealveolina cretacea cf. brevis. The top is dated as upper Santonian (uppermost lower Senonian: upper Cretaceous) by the association Lacazina aff. elongata, Orbitoides tissoti var. densa, Nummofallotia cretacea, and large miliolids.
Deux nouvelles especes du genre Adelograptus (Graptolites) dans l'Ordovicien inferieur du Sahara algerien
Authors: Legrand Philippe
Published: June 2020

Two new graptolite species, Adelograptus bagueli n. sp. and Adelograptus messaoudi n. sp. occur in the lower Ordovician of the Hassi Messaoud region of the Algerian Sahara. Details of rhabdosome development are shown unusually well, and relationships of the genus to Bryograptus are described.
Les bassins sedimentaires du nord de la Corse; essai de synthese stratigraphique et apercu tectonique
Authors: Delcey Roland , Limasset Jean Claude , Routhier Pierre
Published: June 2020

The Saint Florent, Balagne, and Francardo basins of northern Corsica, surrounded by Paleozoic granitic and metamorphic rocks, are occupied by Permian to Triassic arkosic clastics and rhyolite overlain by dolomitic limestones, Jurassic limestones and spilite pillow lavas, Cretaceous flysch and overlying Globotrunca marly and sandy limestones, Eocene arkosic clastics, Nummulite limestone, and flysch. Although the paleogeographic history of the three basins differs in details, it was essentially the same in major features. The tectonic history, however, differed considerably depending on the structural nature of the underlying basement rocks of the basins. Presence of nappes of distant origin is suspected from relationships of the Cretaceous flysch and the Paleozoic schists east of Francardo.
Des oolites volcaniques dans le massif du Mont-Dore
Authors: Brousse Robert
Published: June 2020

A bed of late Tertiary volcanic oolitic concretions occurs at the top of a pumice flow intercalated between two basalt flows in the south flank of the Mont Dore volcanic massif of south-central France. The oolites are ellipsoidal to pear-shaped and have a mean density of only 0.11 as contrasted with 0.5 for pumice. The cores are aggregates of pumice, glass, feldspar, and augite fragments with five to ten concentric shells of the same materials. The oolites are not of aqueous environment. Their positions in the bed indicate they were air-borne and some are radially cracked from impact. The original shattered materials were thrown to great height by a violent eruption, and the oolites were formed by progressive aggregation of the fine fragments in falling back to earth in a manner analogous to the formation of hail.

Authors: Beauvais Marcel
Published: June 2020

The recent study of the cyclolitoid Madreporaria from Gosau, Austria, in the Quenstedt collection at the University of Tuebingen resulted in assigning most of the species to the genus Fungia Lmk. The remainder were reclassified among known species of other genera and a new genus, Plesiocunnolites.
Procymatoceras mazardrikense nov. sp.: nautile jurassique du Baluchistan
Authors: Sarkar Satya S.
Published: June 2020

The nautiloid from the Polyphemus limestone of Mazar Drik in Baluchistan identified by Noetling as Nautilus intumescens Waagen differs in many respects from Waagen's holotype, and from all known nautiloids of India and Pakistan. It is a new species, for which the name Procymatoceras mazardrikense n. sp. is given.
Sur la presence de trois especes de Thecideidae (Brachiopodes) en Roumanie
Authors: Pajaud Daniel , Patrulius Dan
Published: June 2020

The known species of Thecideidae brachiopods in eastern Europe are few, three each in Czechoslovakia and the USSR. The recent discovery of three species in Romania thus is an important contribution. Vermiculothecidea vermicularis Schlotheim occurs in the Maestrichtian (upper Cretaceous) of the southeastern Carpathian mountains. Davidsonella (?) tithonica n. sp. occurs in the Tithonian (upper Jurassic) of the Sinaa area on the headwaters of the Prahova river in the southeastern Carpathians. Agerinella lyrata n. sp. occurs in the upper Oxfordian (upper Jurassic) at the La Adam grotto in the Visterna valley.
Essai de reclassification des Olividae Ancillinae (gastropodes)
Authors: Chavan Andre
Published: June 2020

Review of the gastropod subfamily Ancillinae (Senonian-Recent) shows that certain shell features are more important characteristics for classification than the form of the shell itself. The study includes discussion of the genera Ancilla, Ancillus, Ancellina, Gracilancilla, Amalda, Olivula, and Eburna and their subgenera. A dichotomous key is given for the classification of the Ancillinae.
Contribution a l'etude geologique de la region de l'Albenza (Alpes meridionales, province de Bergame, Italie)
Authors: Blanchet Rene
Published: June 2020

The stratigraphic succession in Lombardy, ranging from the early Jurassic through the Paleocene, exhibits two types of sedimentation; pelagic in the Jurassic and lower Cretaceous, and detrital sedimentation beginning with Aptian pelites and developing to its greatest extent in the flysch facies between the upper Cenomanian and upper Campanian. Similar terrigenous flysch deposits in the Eocene on the west bank of Garda lake indicate that the emerged area furnishing the sediments must have been west of Lombardy.
Indice de sulfures sedimentaires de Taboca (municipe de Crato, etat du Ceara, Bresil)
Authors: Cassedanne Jacques
Published: June 2020

Sedimentary rocks in the southwestern part of Ceara state, Brazil, contain lead, zinc and iron sulfides. The mineralized zone is in unfaulted horizontal beds of lower Cretaceous age. The area of sedimentary sulfur corresponds to a shallow Precambrian basin which exhibits gaps in sedimentation, thinning, and rapid lateral facies variations. The mineralized bed is composed of bituminous shale with limestone pebbles and synsedimentary breccia. It corresponds to a short period of unstable sedimentation intercalated with a series of argillaceous sands, marls and shales.
Les roches et leur equilibre dans la structure du globe
Authors: Machairas Georges
Published: June 2020

The rocks of the earth's crust and upper mantle belong to three categories. The first includes those rocks that have achieved complete equilibrium. Rocks of the second category represent transitory equilibrium, their formation varying relative to the chemical elements available and the physical and dynamic conditions. Rocks of the third category consist of limestones, shales, and other detrital sediments. Their composition is completely controlled by that of the source rock. The global discontinuities including that at the surface, and the Mohorovicic and Lehmann-Gutenberg discontinuities are briefly discussed in terms of differences in densities of rocks of the various categories.
Les formations coralliennes de Saint-Germain-de-Joux (Ain)
Authors: Enay R.
Published: June 2020

Coralline formations in the Saint-Germain-de-Joux area (France) are dated as Kimmeridgian (upper Jurassic) based on their position in relation to ammonite-bearing horizons. Only the lower formation is truly coralline, characterized by the juxtaposition of columnar coral build-ups and limestone detritus. The columnar accumulations reach a height of 50-60 meters and never exceed a few meters in diameter. They are composed of branching corals grouped in 'bunches' and toward the top contain massive colonies. The pericoralline sediments exhibit no bedding and constitute the major part of the formation. An interval of compact limestone and algal nodules separates the lower and upper formations. The upper formation contains no coral structures and is composed almost entirely of pseudo-oolitic limestones, more well-bedded than the lower formation. The coralline formations resemble the Valfin reef but surpass them in size, completeness and preservation. The parallel and linear disposition of these chronologically equivalent zones suggests development in a barrier reef or channel.
Le Sannoisien de Sannois (Seine-et-Oise) dans le cadre du bassin de Paris et sa signification stratigraphique
Authors: Cavelier Claude
Published: June 2020

The Sannoisian (upper Oligocene), exposed only in its upper part at the type section, Sannois, France, is described from paleontologic and lithologic studies at Argenteuil and Cormeilles. Foraminifera and ostracods, less common in the Romainville green shale than in the Sannois limestone, along with previously studied mollusks, indicate that the fauna of the Argenteuil blue marls and the Pantin white marls exhibit an affinity with upper Eocene faunas, whereas the Romainville green shale and the Sannois limestone cannot be distinguished paleontologically from the Stampian. It is concluded from this that the Sannoisian should be suppressed and the type section retained as the type of the Sannoisian facies.
La succession stratigraphique des mammiferes dans l'Eocene du bassin de Paris
Authors: Rat Pierre
Published: June 2020

Reconstruction of the successive mammalian faunas in the Paris basin results in delineation of a stratigraphic sequence that begins with the Cernay-les-Reins conglomerate, containing the oldest Eocene fauna (composed of multituberculate forms) in France. The series continues with the Sparnacian Meudon conglomerate with Coryphodon and Pachaena, the upper Cuisian sands with Lophiodon larteti and the first expansion of artiodactyls, and the Montmartre gypsum in which the first paleotheres appeared. Isolated fossil occurrences give only an indication of other phases--the Sparnacian Soissonnais lignites and the Bartonian Saint-Ouen limestone.
Carte structurale du toit de la craie dans la region parisienne (Seine, Seine-et-Oise, Seine-et-Marne)
Authors: Bricon Claude , Desprez Noel , Diffre Philippe , Megnien Claude , Rampon Gilbert , Turland Michel
Published: June 2020

The first draft of a structure map showing the top of the Chalk formation (upper Cretaceous) in the Paris region is based on 894 cores drilled in the area. The anticlinal and synclinal axes are modified, particularly at the east and at the southeast where domes and shallow basins are present. On the basis of the data, two structural regions are distinguished. To the west, in Seine-et-Oise, there are two anticlinal and synclinal zones paralleling the Armorican direction. The second zone, to the east, in Seine-et-Marne, contains monoclinal structures dipping to the NW. Structures below the Tertiary, among which are anticlines, synclines, domes, and basins, are briefly described in relation to the mapped Chalk-Tertiary boundary.
Analyse mineralogique des sediments arenaces de l'Oxfordien superieur, de l'Albien et d'une formation intermediare dans la region de Lisieux (Calvados)
Authors: Juignet P.
Published: June 2020

A heavy mineral analysis of sands reveals differences between Sequanian (upper Jurassic) and Albian (lower Cretaceous) formations of the Lisieux area, France. The heavy mineral suite in the horizontal well-sorted Sequanian Glos sands shows a predominance of tourmaline, zircon, rutile, and brookite. The Albian green sands differ from the Glos sands by the presence of glauconite, oblique stratification, and poor sorting at the base. A thin sandy bed intermediate between the Albian and Sequanian shows heavy mineral affinities for the Albian suite.
Observations sur le genre Distichoplax (algues melobesiees)
Authors: Denizot Michel , Massieux M.
Published: June 2020

Thin sections from Sparnacian (upper Paleocene) limestone between Limoux and Alet-les-Bains have revealed the lamellar character of the thallus of Distichoplax biserialis. Transverse sections parallel to the cell rows reveal two symmetrical cell layers in the thallus; the quadrilateral form of the principal cells; and the alternation of cortical cells, principal cells and trichocytes. In sections parallel to the thallus large cells followed by small square or polygonal cells are observed. The thallus of D. biserialis is compared with those of living melobesids. The form and dimension of the cells in D. biserialis distinguish it from the Recent forms.
Essai d'explication de la sedimentation cyclique, cyclothemes et megacyclothemes
Authors: Deleau Paul
Published: June 2020

The Namurian-lower Westphalian coal basin at Abadla, southwest of Colomb-Bechar, Algeria, is chosen as an example of a sedimentary basin formed on a great epicontinental platform. The coal epoch was characterized by heavy precipitation suggested by the great amount of water needed to transport sedimentary material over long distances and wide areas. Two continental flexures are recognized--one between the open sea and the sedimentation platform, the other between the platform and the continental beds--and are the determining factor in the cyclical distribution of the sediments. In large basins, as Abadla, where there are thin beds, the compaction of the coal does not occur with the cyclical sedimentation.
Madreporaires du Carbonifere des Hautes-Corbieres
Authors: Semenoff-Tian-Chansky Pierre , Ovtracht Andre
Published: June 2020

A small fauna of madrepores has been discovered in limestone lentils in conglomerates in the Culm (Carboniferous) deposits of the Mouthoumet massif (southern France). The discovery suggests that the area was subjected to some uplift during the terminal Visean stage and prior to the major Hercynian movements that resulted in emergence of the mountains.

Authors: Guevenc T.
Published: June 2020

The new genus Goksuella, five new species, and a new variety of the Bereselleae (dasycladacean algae) are described from the Carboniferous of the western Taurus mountains of Turkey. The new species are Beresella bilguetayae, Dvinella cuvillieri, Samarella massieuxae, Goksuella maslovi, and G. oblica. The new variety Beresella erecta turkiana is also described. The Bereselleae have previously been reported only from the USSR.
Essai d'interpretation de paleomilieux grace a la methode de distribution des formes zoariales chez les bryozoaires
Authors: Labracherie Monique , Prud'homme Janine
Published: June 2020

Curves established in calculating the percentage of different zoarial types of bryozoans found in the Eocene sedimentary beds of a core drilled 25 km north of Bordeaux (France) were analyzed. The observed variations in distribution relative to lithology permit distinction of several groups and, with the help of comparisons with present-day faunas, interpretation of the different faunal environments which existed during the course of sedimentation.
Sur l'evolution du genre Haplocyon Schlosser (Carnivora)
Authors: Bonis Louis de
Published: June 2020

Two different lines, each forming a subgenus, can be distinguished in middle and upper Oligocene carnivores belonging to the genus Haplocyon. The new subgenus Parhaplocyon contains a single species, P. elegans n. sp.; it persists throughout the Stampian to the Aquitanian. The subgenus Haplocyon evolved toward acquisition of a more prominent dentition and was ancestral to the genus Haplocyonides. This group of carnivores constitutes the new subfamily Haplocyoninae.
Structure de quelques polypiers phacelodes triasiques
Authors: Cuif Jean Pierre
Published: June 2020

The Triassic coral genus Thecosmilia includes different forms. The structure of the radial elements as well as the position of the wall and endotheca are fundamental criteria for distinguishing these forms. On the basis of these elements, three new genera are described: Volzeia, Distichophyllum, Retiophyllia. This study shows that the Triassic fauna is more diversified than was originally apparent.
Etude micropaleontologique du Viseen superieur de Djerada (Maroc)
Authors: Chanton Nicole
Published: June 2020

A paleontologic study of the microfauna of the so-called Carboniferous limestone along the margin of the mining district in the Djerada basin (Morocco) confirmed the upper Visean (Mississippian) age previously assigned on the basis of the macrofauna. Three families of foraminifera are particularly important: Archaediscidae, Endothyridae, and Tetrataxidae.
Etude geologique des massifs calcaires du Pied-du-Poul et de Perillos (Aude, Pyrenees-Orientales)
Authors: Bertrand-Sarfati Janine
Published: June 2020

Micropaleontologic data obtained during a study of the stratigraphy of the Perillos and Pied-du-Poul massifs allow precise dating of the limestone series of the southern Corbieres mountains (France). The series comprises three members: bedded Bajocian (Jurassic) limestones; black Bathonian (Jurassic) dolomites with limestone lenses; and a thick monotonous sequence of white limestone with gray or sometimes blue weathering crusts, representing a continuous series ranging from Jurassic to lower Cretaceous. The series proves the presence of an almost continuous shallow sea. Simple tectonic structures are present--overthrusts of small extent indicating a southeast-northwest thrust direction, and vertical faults.
Les laves recentes de l'Etna
Authors: Tanguy Jean Claude
Published: June 2020

The recent lavas of Etna are tephritic trachybasalts always showing the same mineral composition: olivine phenocrysts; phenocrysts and microlites of strongly zoned calcic plagioclase, slightly titaniferous and aluminous augite, and titanomagnetite; [and] interstitial sanidine and nepheline accompanied by a minimum amount of sodalite. These minerals have been studied by chemical analysis, as well as by optical and x-ray diffraction methods. Analyses of plagioclase, augite, and olivine have again been carried out and compared with those already published. Sanidine, nepheline, and sodalite which, although implicit in the total chemical analysis of the rock, had never been explicitly described, have been identified by selective staining, microchemical tests, and x-ray diffraction. This has been followed by chemical and modal analysis of the most representative lavas. An average type has been defined and its place in the classification of volcanic rocks discussed.
Presence d'une fosse d'effondrement volcano-tectonique dans la partie centrale du massif du Cantal
Authors: Vatin-Perignon Nicole , Michel Robert
Published: June 2020

A geophysical program of electric logging indicates the presence, under the Cantal volcanic massif (France), of a zone of volcano-tectonic trenching surrounding the principal centers of eruption. The electric logs contribute useful information on the location, form, and structures of this trench, and confirm the general homogeneity of the volcanic material, probably clastic, filling the trench.
Sur l'age des derniers cataclysmes volcano-tectoniques dans la region centrale de l'arc des Nouvelles-Hebrides
Authors: Geze Bernard

Study of Recent volcanism in the islands of the central region of the New Hebrides arc and the Shepherd group, including carbon-14 dating, confirms a succession of cataclysms within historic time. Submarine volcanoes along the coasts are still very active.
Sur les facies du Cretace inferieur aux environs de Chambery (Savoie)
Authors: Guillaume S.
Published: June 2020

With the help of microstratigraphic analyses, a study was made of the transition in the Neocomian (lower Cretaceous) from the Jura-type facies to the Subalpine facies on Outheran mountain south of Chambery (Savoie, French Alps). The lower Cretaceous boundary of the Jura-type and Subalpine facies has a different direction from the present structure. The transition zone between the platform and the deep basin shifted from southeast to northwest during the Valanginian and Hauterivian.
Le Lias et le Bajocien de La Javie (Basses-Alpes)
Authors: Mouterde R. , Kerrien Yves , Labourguigne Jean , Manivit Jacques
Published: June 2020

In the La Javie area, Basses-Alpes, France, there is a thick, fossiliferous sequence of Liassic sediments; the Aalenian is especially well represented. The Domerian and Toarcian thicken spectacularly northwards from Digne; such thickening is also characteristic of the lower Liassic between Digne and the Blayeul crest. To the east, the beds around the Beaujeu dome are not as thick, and show marked schistosity from tectonic influences.
Observations nouvelles sur le Tithonique terminal et le Berriasien de la region de Luc-en-Diois (Drome)
Authors: Donze P. , Le Hegarat G.
Published: June 2020

The upper Tithonian-Berriasian (uppermost Jurassic-lowermost Cretaceous) section of the Luc-en-Diois region (Drome, French Prealps) includes two conglomeratic sequences separated by marly limestones. Similar sections are known from several surrounding localities. The lower conglomerate at Luc-en-Diois is correlated with the upper Tithonian main breccia of Chomerac in the Ardeche region. The marly limestone contains microfauna of lower Berriasian ostracods. The upper conglomerate, with its associated red detrital limestone, may similarly be equivalent to the upper conglomerate of the Ardeche section; it is probably uppermost Berriasian, marking the Berriasian-Valanginian boundary.
Etude geochimique d'une sequence des 'terres noires'; application au probleme de l'ecologie de spongiaires constructeurs
Authors: Artru Philippe , Gauthier J.
Published: June 2020

The 'black earths' of Diois (French Prealps) and the Laragne region are a monotonous succession of argillaceous and marly beds of late Bajocian to early Oxfordian age. They contain platy limestones and associated lentils of abundant sponge spicules, apparently bioherms, especially near the middle of the sequence. Variable but high sulfur content, constant high boron content, and constant contents of Cr, V, Ba, Sr, and Ga in these rocks indicate euxinic conditions of deposition. The platy limestones represent influxes of colder, more oxygenated water, brought into the deep part of the basin by intermittent currents, making possible the development of the sponge bioherms under semi-euxinic conditions.
Sur l'age (Callovien inferieur) du niveau repere median des 'terres noires' du Diois et de la region de Laragne (chaines subalpines)
Authors: Artru Philippe , Elmi Serge , Mangold Charles
Published: June 2020

The 'middle marker horizon' of the 'black earths,' southeastern France, belongs to the Macrocephalites macrocephalus zone of earliest Callovian (Jurassic) age. Macrocephalites (subgenera Macrocephalites, Kamptokephalites, and Dolikephalites) and Bullatimorphites bullatus (d'Orb.) characterize the horizon. No elements younger than the kamptus subzone were collected; part or all of the macrocephalus subzone may be present. Bullatimorphites, although typical of the Bathonian, has been collected from lower Callovian sections at several localities in France.
A propos de l'age des molasses de Tanaron (Basses-Alpes); la redecouverte du gisement de cerithes et ses consequences structurales
Authors: Beaudoin Bernard , Cavelier Claude , Haccard Daniel , Lanteaume Marcel , Perrin Michel
Published: June 2020

The well-known Cerithium deposit of Tanaron (Basses-Alpes, France) has been rediscovered. Its Helvetian-Tortonian (Miocene) age is in perfect agreement with its position above the typical marine molasse of the Burdigalian and below the Valensole conglomerates. This rediscovery supports the monoclinal, as opposed to the synclinal, interpretation of the relations between the red molasse and the Valensole conglomerates.
Sur l'existence de phenomenes de ravinement, de condensation et de remaniement au sein des formations secondaires de la Sierra de Crevillente (prov. d'Alicante, Espagne)
Authors: Azema Jacques , Sornay Jacques
Published: June 2020

The stratigraphic study of the southern flank of the Sierra de Crevillente (Alicante province, Spain) has produced evidence of erosion and reworking phenomena in the midst of Mesozoic formations. These local features indicate the existence of a shoal zone swept by currents. They compare with those known near Antequera and Ronda, farther west in the southern Subbetic zone.
Le diapirisme des terrains triasiques au Secondaire et au Tertiaire dans le Subbetique du NE de la province de Grenade (Espagne meridionale)
Authors: Foucault Alain
Published: June 2020

The study of certain outcrops in the Subbetic zone indicates diapirism of Triassic strata beginning as early as the Turonian (upper Cretaceous). These movements of the evaporitic strata of the Triassic have had an important influence on the tectonic development of the western Mediterranean. Although deformation of the diapirs by tangential tectonic activity has made them difficult to recognize, they occur on both sides of the western Mediterranean and may be much more widespread than currently believed.
L'evolution sedimentaire et tectonique du bassin hercynien de Moravie-Haute-Silesie
Authors: Unrug Rafal
Published: June 2020

The Moravia-Upper Silesia basin of southern Poland and northern Czechoslovakia is a good example of geosynclinal development. Geosynclinal sedimentation beginning in the Devonian passed gradually without tectonic break into late geosynclinal coal-producing sedimentation. After Asturian (upper Carboniferous) folding, upper Carboniferous and lower Permian sediments were laid down. The migration of subsidence and molasse-type sediments within the geosynclinal system is clearly shown.

Published: June 2020

Various concretionary limestones near the Oligocene-Miocene boundary in the French Central Massif are built predominantly by the activity of cyanophycean algae. The structure, which macroscopically appears very diverse, is microscopically uniform, comparable to certain ancient and modern stromatolites.
Etude micropaleontologique de l'Albien, du Cenomanien et du Turonien d'Audignon (Landes)
Authors: Saint-Marc Pierre
Published: June 2020

The Audignon anticline is one of the most studied folds of Aquitaine [southwestern France]. Up to now the stratigraphy has commonly been based on the lithology and macrofauna. The study of microfaunas and microfacies has contributed to the establishment and refinement of the stratigraphic series of the Albian, Cenomanian, and Turonian [Cretaceous], and to their correlation with those of Roquefort-des-Landes.

On the basis of geomorphic criteria, five levels corresponding to Quaternary glaciations can be distinguished in the terraces along the Rhone in southern France. From highest to lowest, they are: the Donau, Guenz (two levels), Mindel, Riss (two levels), and Wuerm. Each level is described in detail.
Biostratigraphie et paleoecologie des peuplements a huitres et des formations saumatres du Santonien provencal
Authors: Fabre-Taxy Suzanne , Philip Jean
Published: June 2020

Detailed biostratigraphic studies of oyster faunas and brackish formations from the Santonian (upper Cretaceous) of Provence (southern France) show lateral and vertical variations of ecologic zones resulting in recurrent faunas. The basal beds correspond to a brackish near-deltaic facies, while a marine transgression is represented in the major part of the sequence. The Santonian is terminated by a second brackish sequence. These three zones pass laterally and vertically into fresh-water formations of the Valdonnian or into deltaic facies poor in fossils.
Note preliminaire sur le Tertiaire superieur du Chili centre-nord
Authors: Herm Dietrich , Paskoff Roland
Published: June 2020

Research on the faunal evolution of the marine Neogene in north-central Chile (D. H.) has shown the existence of an important sedimentary hiatus between the upper Miocene and the upper Pliocene. Other work carried out independently (R. P.) shows that the lower Pliocene corresponds exactly to a period of great activity of exogenetic forces on the continent related to very low sea level. Two basic facts appear in the light of these observations: on the one hand the existence of continental deposits of the lower Pliocene in the bottoms of present valleys, on the other hand the necessity of adopting, to account for Plio-Quaternary events, a 'long' chronology that refers to the beginning of the Pliocene the great dislocations that have given the Andean system its mountainous proportions.
Le Neocomien de la region du Bas-Verdon
Authors: Belleville Jean Michel , Chevalier Jean
Published: June 2020

The Neocomian (lower Cretaceous) of the lower Verdon region (Basses-Alpes, southern France) represents a transition facies between deep-water marine deposits to the northwest and continental deposits to the southeast. The facies change between the marly limestone series of the flexure zone to the west and the white limestone series of the platform to the southeast can be traced. Fluctuations of the ancient shoreline resulted in alternations of bioclastic marine limestones and lacustrine sediments.
Paleogeographie, orogenese, metamorphisme et magmatisme des zones internes des Hellenides en Macedoine (Grece); vue d'ensemble
Authors: Mercier Jacques
Published: June 2020

Since the end of major Hercynian disturbances in the upper Paleozoic, the inner Hellenide zones, including the Peonia and Almopia troughs and the Paikon and Pelagonian ridges, have been affected by several periods of complex orogenic activity among which were four phases of tangential movements: Portlandian or terminal early Cretaceous, terminal Cretaceous to lower-middle Eocene, latest Priabonian, and post-lower Oligocene. Vertical movements took place before the last tangential phases, during Kimmeridgian-Portlandian and Turonian-Campanian time. Since the Hercynian and pre-Hercynian periods of metamorphism the inner Hellenides have been affected by dynamic metamorphism of post-Jurassic-pre-Albian-Aptian and post-Maestrichtian-pre-lower Oligocene age; post-middle-upper Eocene dynamic metamorphism had localized effects near structural contacts. Igneous activity associated with the metamorphism and orogenic movements was initially (Jurassic) ophiolitic; two phases of synorogenic (upper Jurassic-early Cretaceous and late Cretaceous to lower-middle Eocene) granitic activity followed and were in turn succeeded by three phases of postorogenic (Plio-Quaternary) andesitic, granitic-granodioritic, and basaltic activity.
Grandes structures de la mer Ligure, leur evolution et leurs relations avec les chaines continentales
Authors: Glangeaud Louis , Alinat Jean , Polveche J. , Guillaume Andre , Leenhardt Olivier
Published: June 2020

Data obtained during the Geomede I cruise and other oceanographic surveys have made it possible to define the major structural units of the Ligurian sea. They are thought to be related to continental structures of Corsica, the French-Italian continental margin, and the Alps. Significant relationships therefore exist between the Alpine continental structures and the submarine paleogeographic and tectonic units of the Mediterranean.

Sommaire

La hutte Chaumont à Champlan (feuille de Corbeil-Essonnes 1/50 000, x = 112,45 ; y = l12,45) est une hutte de sables stampiens coiffée de calcaire d'Étampes plus ou moins meuliérisé. Elle est située à l'endroit où les vallées de l'Yvette et de la Bièvre se rapprochent le plus, à la limite orientale du plateau de Beauce. Son altitude est de 136 m. L'exploitation active du sable de cette butte nous a permis de la visiter et de relever les profils de plusieurs fronts successifs (novembre l966 à novembre 1968), particulièrement le long du front principal dont la direction est NNW­SSE. La figure 1 présente les relations entre les divers éléments rencontrés sur ces coupes successives.

Background: The prevalence of non-cystic fibrosis (CF) bronchiectasis is increasing in both developed and developing countries in recent years. Although the main features remain similar, etiologies seem to change. Our aim was to evaluate the clinical and laboratory characteristics of our recent non-CF bronchiectasis patients and to compare these with our historical cohort in 2001. Methods: 104 children with non-CF bronchiectasis followed between 2002 and 2019 were enrolled. Age of diagnosis, underlying etiology and microorganisms in sputum culture were recorded. Clinical outcomes were evaluated in terms of lung function tests and annual pulmonary exacerbation rates at presentation and within the last 12 months. Results: Mean FEV1 and FVC %predicted at presentation improved compared to historical cohort (76.6±17.1 vs. 63.3±22.1 and 76.6±15.1 vs. 67.3±23.1, respectively; p<0.001). There was a significant decrease in pulmonary exacerbation rate from 6.05±2.88 at presentation to 3.23±2.08 during follow-up (p<0.0001). In 80.8% of patients, an underlying etiology was identified. There was an increase in primary ciliary dyskinesia (PCD) (32.7% vs. 6.3%;p=0.001), decrease in idiopathic cases (19.2% vs. 37.8%;p=0.03) with no change in postinfectious and immunodeficiencies as underlying etiology. Sputum cultures were positive in 77.9% of patients which was 46.9% in the historical cohort (p=0.001). Conclusion: Baseline pulmonary function tests were better and distribution of underlying etiology had changed with a remarkable increase in diagnosis of PCD in the recent cohort.
Survival outcomes of neoadjuvant versus adjuvant chemotherapy in triple-negative breast cancer: a meta-analysis of 36480 cases. ﻿

Background: The survival outcomes of neoadjuvant chemotherapy (NACT) versus adjuvant chemotherapy (ACT) for patients with triple-negative breast cancer (TNBC) remain unclear. Therefore, in this study, a meta-analysis was conducted to analyze current evidence on the survival outcomes of NACT versus ACT in TNBC. Methods: A systematic search was performed on the PubMed and Embase databases to identify relevant articles investigating the survival outcomes of NACT versus ACT in TNBC. Results: A total of nine studies involving 36480 patients met the selection criteria. Among them,10728 (29.41%) received NACT, and 25752 (70.59%) received ACT. The pathological complete response (pCR) rate was 35% (95% CI = 0.23-0.48). Compared with ACT, the overall survival (OS) of NACT was poor (HR = 1.59; 95%CI = 1.25-2.02; P=0.0001), and there was no significant difference in disease-free survival (DFS) between the two treatments (HR = 0.85; 95%CI = 0.54-1.34; P=0.49). NACT with pCR significantly improved the OS (HR = 0.53; 95%CI = 0.29-0.98; P=0.04) and DFS (HR = 0.52; 95%CI = 0.29-0.94; P=0.03), while the OS (HR = 1.18; 95%CI = 1.09-1.28; P<0.0001) and DFS (HR = 2.36; 95%CI = 1.42-3.89; P=0.0008) of patients with residual disease (RD) following NACT were worse compared to those receiving ACT. Conclusion: These findings suggest that, for TNBC, NACT with pCR is superior to ACT in improving OS and DFS. and it turns to be opposite when patients receiving NACT with RD.

Esse trabalho foi caracterizado por ser um projeto de cultura e extensão universitária visando expandir os conhecimentos da Universidade de São Paulo para a comunidade. De forma educativa e expositiva, objetivou-se correlacionar aspectos sobre a anatomia e arte, mostrando a importância histórica, desde a época pré-histórica até os dias atuais. O trabalho foi realizado com alunos do Ensino Médio em escolas estaduais do estado de São Paulo, sendo atingidos 210 alunos no total. Os alunos participaram de apresentações que mostravam obras artísticas correlacionadas com peças anatômicas. Observou-se que os resultados condisseram com a realidade da educação brasileira, em que 150 alunos, (74%) não dedicavam nenhum tempo fora da escola para o estudo da arte. Constatou-se que os alunos tinham informações sobre o tema (114 alunos, 56%), as quais obtiveram pela internet e nas aulas de artes, demonstrando uma evolução no modo de comunicação e obtenção de informações. Concluiu-se que os alunos se sentiram gratificados pela apresentação, o que foi observado pela análise qualitativa realizada com o instrumento de avaliação.Descritores: Anatomia; Arte; Ensino Fundamental e Médio.ReferênciasAzevedo Junior J.
