Sur une particularite anatomique de certains poissons du Permo-Carbonifere des bassins de Commentry et Autun
Authors: Blot Jacques , Heyler Daniel
Published: March 2020

Paramblypterus decorus, a fossil fish occurring abundantly in the Stephanian (upper Carboniferous) of the Commentry basin near Montlucon in central France, differs from most palaeoniscids in having no teeth on the maxillary and the mandible. Instead, these are separated by a striated zone (five to six millimeters in a fish 30 centimeters long) bearing a line of extraordinarily small teeth each at the end of a small tube-like structure. These structures are known also in Aeduella, a genus of the middle Autunian (lower Permian). Specimens from the Autunian of the Autun basin northeast of the Commentry basin resemble those from Commentry, but their state of preservation does not permit more than tentative referral to P. decorus. These two probably identical forms from neighboring basins indicate no important stratigraphic break between the Stephanian and the Autunian in central France. Further investigation of the palaeoniscids is required to evaluate the relationship between P. decorus and the genus Aeduella, and to learn whether this unusual structure of the buccal region appeared before the Stephanian.
Bassin houiller de Durban-Corbieres (Aude, France)
Authors: Ovtracht Andre , Vila Jean Marie
Published: March 2020

Upper Carboniferous plant-bearing beds crop out in a coal basin along the Berre river, near Corbieres. The beds, from bottom to top, include red conglomerates with elements of Ordovician schist, arkosic schists and argillites, sandy schists, conglomerate, arkose-sandstone, and a second bed of red conglomerate with Ordovician elements unconformably overlying the series below. This sequence unconformably overlies Ordovician schists with no evidence of beds representing Gotlandian-Dinantian deposits. The beds thicken rapidly from northeast to southwest and are overlain unconformably by the middle Triassic Muschelkalk dolomites which are in turn overlain by the upper Triassic Keuper marls. The discordance of the Mesozoic on the Carboniferous and the similarity between the upper- and lowermost beds in the basin suggest that the Carboniferous beds represent a fold overturned to the south and eroded prior to deposition of the Triassic. Plant remains collected from the sandy schists suggest a Stephanian age. Abundant Sphenopteris and Pecopteris are among the significant genera represented.
Stratigraphie des terrains dinantiens de l'Argentella-Tour Margine (nord-ouest de la Corse)
Authors: Krylatov Serge
Published: March 2020

The Argentella-Tour Margine outlier, surrounded by Hercynian granites, consists of a crystalline metamorphic series overlain with angular disconformity by a sedimentary series. The metamorphics, produced by regional and subsequent contact metamorphism, are primarily schistose quartzites with chlorite, sericite, and occasional biotite. This pre-Visean series contains carbonaceous shale characteristic of the Gothlandian, and is overlain by rocks containing a Visean limestone. The sedimentary series is divided into a lower group consisting primarily of arenacous schists locally containing successive beds of monogenic conglomerates, sandstone-quartzites, the lower jasper (Lydianstone), and polygenic puddingstone, and an upper group (Tour Margine formation) composed of an intimate mixture of albitophyres and volcano-sedimentary rocks with isolated beds of the upper jasper, and encrinital limestone (Capitello) of Visean age.
Etude preliminaire des argiles eocenes, mio-pliocenes et actuelles de la region de Metlaoui-M'Dilla et du cap Bon (Tunisie)
Authors: Sassi Sassi B. M.
Published: March 2020

Eocene and Mio-Pliocene formations of the Gafsa region are differentiated by their clay minerals. The clays of the El-Haria formation are composed of equal amounts of montmorillonite and kaolinite. The overlying Eocene marine clays of Djebel M'Dilla are composed of montmorillonite, illite and traces of kaolinite, and include a bed of clay containing montmorillonite and sepiolite-attapulgite. The continental Mio-Pliocene deposits around Djebel M'Dilla contain a suite of minerals including kaolinite, attapulgite, illite, montmorillonite and chlorite. These minerals apparently do not have authigenic characteristics. Diffractograms obtained from these deposits indicate pronounced crystallinity of the minerals. Mineralogic variation in the clay lenses shows that, from the base to the top, illite and, to a lesser degree, kaolinite, gain importance at the expense of the montmorillonite. At Cape Bon, the Oligocene is rich in kaolinite with subordinate amounts of illite and montmorillonite. Vindobonian, Pliocene and Recent deposits contain the same phyllites but with kaolinite and montmorillonite in equal proportions and a lesser percentage of illite. The uniformity exhibited by the Miocene clays--suggesting monotonous accumulation from a single source of supply--reaffirms the fact that the composition of clays depends more on the nature of the source of supply than on the diagenetic modification produced in the course of sedimentation. The montmorillonitic mineral of these deposits is an unstable phyllite intermediate between a classic montmorillonite in the Eocene and an ammersoite in the post-Eocene.
Relations geometriques et chronologiques entre les series sedimentaires, les schistes lustres et le granite dans le Sud de la Corse alpine
Authors: Bloch Jean Paul
Published: March 2020

Several localities in alpine Corsica were studied for the purpose of determining the age of the schistes lustres and their relationship with the sedimentary and granitic series. Since the Abatesco sedimentary series passes imperceptibly to the north into the schistes lustres, the relationship between the Abatesco and the granitic series and between the Abatesco and the Solaro formation is examined to determine the nature of the contacts. In places where the contact between the sedimentary series and the underlying granite is visible there was no evidence of the intrusion of the granite into the sedimentary rocks. On the contrary, the sedimentary series is transgressive on the granite as indicated by a basal conglomerate. The contact between the two dips slightly, leveling off to the north and overturning, placing the granite over the sedimentary series, and suggesting tectonic forces moving from west to east. The Eocene Abatesco and Solaro series are placed in the Fium' Orbo series which represents the detrital, somewhat metamorphic facies of the schistes lustres complex. The presence in the schistes lustres of black quartz--from the basement complex--makes it possible to assign a Paleozoic age to the series. The preferred theory is that the schistes lustres are Eocene, in part, and pass longitudinally into a sedimentary series well-rooted in the granite.
Les ensembles tectoniques betiques de la region de Lorca (Espagne meridionale)
Authors: Fernex Francois
Published: March 2020

The Betic units of the Lorca area belong to the Alpujarride domain and to the Betic of Malaga Three units, slightly affected by Alpine orogenic movements, comprise the Alpujarride. The Lajara unit consists of middle and upper(?) Triassic limestones and dolomites overlying Werfenian sandstones and sericite schists. The Simon-Torrecilla unit is composed of Permo-Carboniferous micaschists overlain successively by upper Permian phyllitic schists Werfenian sericite schists and quartzite, and middle-upper Triassic limestones and dolomites. In the Selvalejo unit, analogous to the Simon-Torrecilla, the basal mica schist overlies the Simon-Torrecilla sericite schists and is generally separated from the Permo-Werfenian which rests directly on middle-upper Triassic limestone-dolomite. Intermediate between the Alpujarride domain and the Betic of Malaga is the Pena Rubia unit, a series of argillaceous sandstones with interbedded conglomerates, similar to the Malaga Betic, overlain by dolomitic limestones of the Muschelkalk and limestone of the Alpujarride facies. In the Betic of Malaga two sub-units are defined, the lower Moroticos-Olivares, composed of Devonian-Carboniferous limestones or dolomites, Permo-Triassic conglomerates, and upper(?) Triassic dolomites. The upper sub-unit, Cimbre de la Fuensanta, is distinguished from the lower unit by the presence of dolomites and limestones containing a Liassic fauna. The characteristics of the intermediate Pena Rubia unit indicate that the two Betic elements were closely related prior to Tertiary folding.
Note preliminaire sur les jaspes dinantiens des Pyrenees et leur cortege
Authors: Krylatov Serge
Published: March 2020

The classification and terminology for the siliceous rocks discussed are briefly outlined. A study of the rocks in the northern Pyrenees, between the Aspe valley and the Mouthoumet massif, makes it possible to establish the succession of jaspers and the other members of that suite. The Visean jaspers unconformably overlie Devonian strata, the result of Bretonian movements of the Hercynian orogeny. The lower jasperoid is composed of carbonaceous shales, lydianstone, and phosphatic nodules; it passes progressively into the upper jasperoid, characterized by tuffs and jasper with lenses of manganese. The jasperoid formation is overlain by limestone containing cherts. Dinantian flysch overlies the limestone. This succession is not complete at any one locality but varies laterally with beds appearing or disappearing.
Precisions nouvelles sur la stratigraphie et la faune du gisement villafranchien de Saint-Prest (Eure-et-Loir)
Authors: Bourdier Franck , Lacassagne Henri
Published: March 2020

The mammiferous beds of Saint-Prest, northeast of Chartres (France), are composed of fluviatile alluvium containing fine sands, gravels, and blocks of chert. The chert shows two sets of striations probably resulting from separate periglacial soilflows. These beds overlie chert-bearing clays and the Thimerais sands. Variegated gray and yellow mud of eolian or fluvial origin overlies the fluviatile deposits and is overlain by a series of loess deposits. The muds and loess represent Guenz to post-Wuerm deposition. The absence of mastodon remains and the presence of relatively advanced forms of rhinoceroses, horses, and elephants in the fluvial beds indicates that the fauna is definitely Villafranchian and that the Saint-Prest beds belong to the Guenzian complex.
Note preliminaire sur un 'cortege' granitique dans la region de Teixeira (Etat de Paraiba, Bresil)
Authors: Meunier Andre R.
Published: March 2020

The upper Precambrian Ceara series, comprising a variety of structurally associated granites, outcrops in northeast Brazil. They are petrographically distinct units, however, differentiated in time and space and three varying manifestations of granitization are represented. The granitic axis of Teixeira, elongated E-W, has a gneissic texture, is equigranular and hololeucocratic, and contains less than 5 percent dark minerals. The satellite massifs also follow E-W structural lines, and are characterized by their uniform lithologic composition. They are dark granodiorites composed of plagioclase and microcline phenocrysts of approximately one centimeter, separated by inclusions of biotite. About 20 percent of the rock is quartz appearing as polycrystalline agglomerates. The Itapetim massif follows the same structural lines. It is a gneiss with embrechite facies and mica schists. It is not homogeneous but rather shows gradual transitions with neighboring formations. The distinctive feature common to these varying granitic units is their migmatitic composition. The succession of the granites has not yet been precisely determined, although their association in the same structural complex permits their attribution to a single suite.
Etude geologique de la rive occidentale du lac de Garde, de Gargnano a Limone (Alpes meridionales, province de Brescia, Italie)
Authors: Geyssant Jacques
Published: March 2020

The stratigraphic sequence of the Garda lake region contains varied facies of marine Triassic to Lutetian rocks. The zone borders the Tridentine zone to the east and the Lombardian depression on the west. The lower Liassic is a thick shallow water facies decreasing in thickness and displaying deep water characteristics in the upper Liassic. The Cretaceous is a white limestone series that progressively becomes more terrigenous as it grades upward to the Eocene.
Etude geologique de la region situee a l'ouest de Rovereto (Alpes meridionales, province de Trente, Italie)
Authors: Rampnoux Jean Paul
Published: March 2020

The NE-SW trending Stivo-Cornetto anticline (Trento province) forms a line of crests separating the Sarca valley from the Adige river valley. The entirely marine sequence includes Liassic and Dogger subreefal limestones succeeded by Malm, Cretaceous and lower Eocene deep water deposits. Emergence or regression resulted in the deposition of neritic facies during the middle and upper Eocene and the Oligocene and Miocene. The deposits are representative of the Tridentine zone.
Nouvelles donnees sur le Paleozoique du massif de l'Arize (Ariege)
Authors: Perseil Elena Adriana , Tourenq Claude
Published: March 2020

The Arize massif lies between Foix and Saint-Girons in southwest France. The Ordovician rocks of the massif include horizons of quartzites, microconglomerates, and puddingstones which can be correlated to the Caradocian of neighboring regions. Graptolites indicate that the overlying strata are lower Silurian. On the basis of the appearance of the trilobite Parahomalonotus a lower Devonian age can be assigned to a slightly magnesian limestone. A possible hiatus existed during the middle Devonian after which the Devonian red-gray limestones and slightly magnesian grits were deposited, followed by a hiatus during Tournaisian time. The lower Visean schist contains phosphate nodules, the percentage of P 2 O 5 in the nodules being a function of their diameter.
A propos de l'age de la serie ophiolitique dans les Dinarides yougoslaves; la coupe de Mihajlovici aux confins de la Serbie et du Montenegro (region de Plevlja, Yougoslavie)
Authors: Aubouin Jean , Cadet Jean Paul , Rampnoux Jean Paul , Dubar Gonzague , Marie Pierre
Published: March 2020

The Mihajlovici area in southwestern Yugoslavia is a mosaic of fault blocks produced by two sets of large faults, trending NW and NE. The horsts are lower Jurassic limestone, and the grabens are occupied by diabase-radiolarite, known as the ophiolitic series, of lower Malm age (upper Jurassic). Abundant ammonites and microfauna identify several horizons, notably the Toarcian (upper Lias, i.e., lower Jurassic) and the uppermost bed of the lower Malm, thus fixing the Malm age of the ophiolitic series.
Les problemes du massif de l'Aston dans les Pyrenees de l'Ariege
Authors: Raguin E.
Published: March 2020

The Aston gneiss-migmatite massif (Hercynian) on the headwaters of the Ariege river in southern France is made up of the Riete augen gneiss, small bodies of the Peyregrand gneiss to the south and southwest, and migmatite bordering these except on the north. The Ax-les-Thermes muscovite granite, accompanied by abundant aplite and pegmatite, lies in the northeastern part of the massif. This granite is similar to the granite stringers in the Riete gneiss. Small granite bodies crop out in the southwestern part of the massif. The massif is surrounded by Paleozoic mica schists except on the south, where the boundary is the Merens fault. The pattern of folding peripheral to the massif suggests movement of a sole under the massif, renewed during the Alpine tectonism.
Sur la structure des coquilles des oeufs des Sauropsides vivants ou fossiles; le genre Psammornis Andrews
Authors: Dughi Raymond , Sirugue Francois
Published: March 2020

The mineralized portion of the shells of reptile eggs forms a simple layer of calcium carbonate spheroliths, but in the eggs of birds an additional layer occurs in which arrangement is not spherolithic. The fossil Psammornis rothschildi, the only representative of the genus from the Miocene and Pliocene of the northern Sahara region, has a thick shell characterized by air canals less closely related to those of the Struthioniform and Aepyornithiform types than to the Rheiform and Dinornithiform types.
Etude d'un nouveau Notagogus de la province de Lerida (Espagne)

A new species of fossil fish of the family Macrosemiidae, Notagogus ferreri n. sp., is described from the Kimmeridgian (upper Jurassic) lithographic limestone at Santa Maria de Meya in Lerida province, Spain.
Presence de masses de materiel triasique englobees dans les marnes miocenes au sud de la Sierra de Ricote (province de Murcie, Espagne)
Authors: Combes Alain
Published: March 2020

The Sierra de Ricote, a part of the Subbetic zone of southeastern Spain, is made up of intensely deformed limestone, dolomite, and other rocks of Mesozoic age. The adjoining Murcie basin is occupied by Miocene limestone and sandy blue marls. The limestone crops out as a hogback ridge against the south flank of the Sierra de Ricote, and the overlying marls to the southeast contain interlayered, poorly-stratified deposits of Triassic marl, gypsum, dolomite, and ophite of Triassic age in blocks up to 60 centimeters in diameter. These deposits represent mudflow masses of Triassic rocks from the Sierra de Ricote that were carried out to the edge of the Miocene sea. They probably represent tectonic movements during the Vindobonian (Miocene).

The ostracod fauna of the Montian (lower Eocene) limestone of the Paris basin has many of the same species found in the Mons basin in Belgium, as well as in Holland. The Tringinglymus beds (faunizone 7) in the Mons limestone are not found in the Paris basin.
Sur l'origine periglaciaire de petits lacs du massif d'Aubrac
Authors: Rousset Claude
Published: March 2020

The Aubrac mountains of southern France, a massif of granite and metamorphic rocks overlain by a thick accumulation of basalt flows, are covered with glacial deposits in which occur 372 small lakes formed by periglacial melting of blocks of ice entombed in the deposits left by the retreating glacier. Most of the lakes are in the summit zone of the mountains but small numbers are scattered on the lower slopes.
Observations lithostratigraphiques nouvelles sur la serie de base (Ordovicien inferieur) des nappes de Cabrieres, region de Gabian-Glauzy (Montagne-Noire, Herault)
Authors: Gonord Henri , Ragot Jean Paul , Saugy Luc
Published: March 2020

A previously unsuspected series of volcanics has been discovered on the southeastern flank of the Montagne Noire in southern France. The lower Arenig-upper Tremadoc beds (Ordovician) are overlain successively by a lower pyroclastic series, andesitic porphyrite, and an upper detrital volcanic series. The volcanics are overlain by Devonian and Caradoc (Ordovician) strata of the Cabrieres nappe. The age of the volcanics is middle Arenig to Llandeilian (Ordovician).
Sur quelques difficultes rencontres en biometrie, et particulierement en paleobiometrie
Authors: Jekhowski Benjamin de
Published: March 2020

Certain difficulties in the analyses of fossil populations require a decision as to whether the population is characteristically homogeneous or must be broken into sub-populations. Choice of parameters, constitution of lots, precision of measurements, probability, interpretation of results, and other problems are discussed.
Le 'volcan' de Beaulieu, pres Rognes (Bouches-du-Rhone)
Authors: Gueirard Simonne
Published: March 2020

The lower Tertiary Beaulieu basaltic volcano near Rognes in southern France had two episodes of activity, emitting pre-Stampian (pre-middle Oligocene) olivine basalt with lherzolite nodules, and a terminal upper Stampian (terminal middle Oligocene) dolerite flow with a pegmatoid facies. An upper Stampian conglomerate including volcanic fragments and also lenticular limestones lies between the flows. Terminal upper Stampian marl and limestone overlie the dolerite. The volcanic conduit probably lies at the intersection of a cross fault with one of the major northwest-trending faults characterizing the region.
Les serpents du Neogene du Pakistan (couches des Siwaliks)
Authors: Hoffstetter Robert
Published: March 2020

Acrochordus dehmi n. sp., an aquatic piscivorous serpent from the Chinji and Nagri formations (upper Miocene) and the Dhok Pathan formation (lower Pliocene) in northern West Pakistan belongs to a family unknown in fossil form, and a genus no longer inhabiting the Indian peninsula. Its nearest living relatives are in the Bangkok region of Thailand, 3,500 kilometers distant. A size of 2.5 meters was attained in the upper Eocene, but the largest found in the lower Pliocene is 2.0 meters. The difference may represent only a smaller sampling from the lower Pliocene. One vertebra of an extinct python was found in the lower part of the Chinji formation, but lack of additional information precludes a description of the species.

La transgression du Cretace superieur ('flysch nord-pyreneen') sur le massif des Cinco-Villas (Pyrenees basques)
Authors: Feuillee Pierre , Sigal Jacques
Published: March 2020

The lower beds of the upper Cretaceous Pyrenean flysch in the San Sebastian area and on the border of the Cinco-Villas Paleozoic massif (western Spanish Pyrenees) exhibit variations in age and in facies. During the Cretaceous the San Sebastian region was an area of continuous sedimentation, the lower Cretaceous underlying concordant Cenomanian marl-limestone formations. Toward Cinco-Villas, lacunae in sedimentation occur within the concordant formations and become increasingly common, corresponding to a transgression which lasted from the Cenomanian to the lower Senonian. Along the border of the massif, flysch overlies Paleozoic units with the intervention of breccias. The transgressive beds, consisting of microbreccias with reworked facies and faunas, are probably Coniacian or possibly upper Turonian. The transgression of the northern Pyrenean flysch reached the Cinco-Villas massif at the beginning of the lower Senonian (uppermost Cretaceous).
Etude de quelques basaltes de l'Aubrac a la microsonde de Castaing
Authors: Colin Felix , Poyet Pierre
Published: March 2020

Preliminary microprobe studies of the Aubrac lava flows (France) show basalts in the lower part of the series and porphyritic peridotites in the upper part. An increase in porphyries, ascending in the series, suggests an evolution towards a supersaturated limit. The basal basalts contain only one oxide--probably ulvoespinel a higher bed contains ulvoespinel and ilmenite, and the overlying peridotite contains ulvoespinel, ilmenite, and titanomagnetite. A comparison of the results shows a relationship between the mineralogy of the ferrotitanian oxides and the iddingsitization of the olivines.
Plissements assyntiens, bakaliens, cadomiens
Authors: Graindor Maurice Jacques
Published: March 2020

Assyntian, Baikalian, and Cadomian have been used in France as equivalent terms to designate a single stage of folding between the end of the Proterozoic and the beginning of the Paleozoic. A reexamination of the definitive character of these terms has shown that they were of unequal length, each with a different succession of episodes. The apparent preference for Assyntian over Cadomian, and the disagreement over the relative age of the purple conglomerate series at the base of the Paleozoic recommend the retention of the Assyntian at the expense of Cadomian. The Assyntian is the last of four transitional periods and includes regional phases.
Caracteres sedimentologiques et micropaleontologiques des formations de Ducy, Mortefontaine, Saint-Ouen et des marnes a Pholadomya ludensis dans le Bartonien du bassin de Paris
Authors: Lorenz Jacqueline , Pomerol Charles
Published: March 2020

Of the four Bartonian formations studied the Ducy formation is the most lagoonal, and the Mortefontaine formation the most marine. The Saint-Ouen formation was deposited in a lagoon somewhat more saline than that of the Ducy formation, suggesting a salinity gradient increasing towards the west. This same gradient is found in the marls containing Pholadomya ludensis where the abundance of charophytes and the microfauna in the eastern part of the basin, indicate brackish deposition in agitated waters. In all the formations, the percentage of attapulgite and sepiolite increases with the lagoonal character.
Presentation de cinq especes nouvelles et de nouveaux representants de gasteropodes dans le Lutetien et le Bartonien du bassin de Paris

Published: March 2020

A series of basal Cretaceous (Valanginian-Albian) limestones is described from the area between Orthez and Saint-Esteben (western France). The series forms a monocline, dipping 45 degrees west. Toward the south the series becomes a faulted anticline and is connected with the Saint-Palais anticline. The fold is thrust to the east onto the Escos syncline by a network of upper Cretaceous and Tertiary faults.

On the basis of fragmentary remains of small mammals, mainly cricetid rodents, three new species (Ruscinomys thaleri, Cotimus leemanni, Cricetulodon sabadellensis) and one new genus (Cricetulodon) are described; their stratigraphic significance in the Sabadell deposits is outlined.
Sur les flyschs et les molasses du cycle alpin dans les Dinarides yougoslaves
Authors: Ciric Branislav
Published: March 2020

The composition, mode of appearance, and the alternation in the flysch deposits of the Yugoslavian Dinarides indicates that they are of orogenic origin, formed during a period of emergence of cordilleras and sunken synclinal troughs. The terrigenous material came from land bordering the sea and from the basement rocks and the overlying deposits of the cordillera. The flysch deposition was preceded by a period of folding. The molasse deposits (Eocene to Miocene) were formed in the final phase of the geosyncline. Differences and similarities between molasse and flysch deposits indicate that the molasse is fossiliferous and usually contains carbon and bituminous shales, while the flysch has no macrofauna and a sparse microfauna. The conglomerate series in the flysch is not recognized in the molasse. The flysch formations in the area are Anisian, Albian-Cenomanian, Maestrichtian-Danian, and upper Eocene.
Etude stratigraphique et hydrogeologique de l'extremite meridionale de la Hamada du Guir

The Miocene and lower Pliocene sandstone and overlying limestone, and the upper Pliocene and Quaternary sedimentary rocks and detrital deposits of the southern portion of the Hamada du Guir (Algeria) rest upon the eroded surface of deformed Paleozoic basement rocks. Significant amounts of ground water in the upper Tertiary sandstones are indicated by four wells in the area west and northwest of Beni-Abbes. Solution pockets and channels, travertine, and other vestiges of ground water are widespread in Quaternary deposits.
Les charnockites du Salto Necuima (Sierra de Imataca, Guyane venezuelienne)
Authors: Verdier Joel
Published: March 2020

The charnockites of the Imataca series (Precambrian) of the Sierra de Imataca, Venezuela, are associated with gneisses and ferruginous quartzite beds. The stratiform nature of the associated rocks, particularly the ferruginous quartzites, and the absence of genetically related eruptive rocks suggest a sedimentary origin for the charnockites. Hypersthene dolerites in the series seem to be younger sills entirely independent of the charnockites. The Venezuelan charnockites are similar to the hypersthene series of Tanezrouft in the southern Sahara and to the charnockites of India.

Contribution a l'etude sedimentologique de la formation des 'gres a Roseaux' (Keuper moyen) dans la region de Hinckange (Moselle)
Authors: Desprairies Alain , Palain Christian , Plaziat Jean Claude
Published: March 2020

In the arenaceous facies of the middle Keuper (Triassic) Roseaux sandstone formation (Moselle, France) channel sandstones occur above obliquely cross-bedded sandstones. A rhythmic succession is observed in which the initial unit is a breccia derived from erosion of older units. The erosion scars can be recognized almost solely by the presence of the breccias, but the extent of reworking can be determined by granulometric and clay mineral studies. Rhaetian (upper Triassic) sandstones are clearly distinguishable on the basis of their clay minerals. On the other hand, broad analogies can be recognized between the Roseaux sandstone, the sandstones of the Lettenkohle formation, and the paralic-type Swiss molasse deposits.
Le cratere de Tenoumer (Mauritanie) et ses laves
Authors: Monod Theodore , Pomerol Charles
Published: March 2020

In this preliminary study of the Guelb Tenoumer, the authors determine the distribution of the lavas and their nature: they are not basalts as might be supposed from their appearance, but rhyodacites. No fact can at present support the hypothesis of a meteoritic or explosive origin of this crater which the authors consider as a collapse caldera, apparently of a type with ring-dikes.
Chrome, nickel et cobalt dans les laves de la region du Mont-Dore
Authors: Letolle Rene , Kulbicki G.
Published: March 2020

These three elements [chromium, nickel, and cobalt] have been determined by UV spectrography in 150 eruptive rocks from Mont-Dore [France], ranging from the Miocene to the present. The behavior of the elements studied is analyzed as a function of the contents of iron and magnesium. The evolution of the series is compared from this angle with that of a certain number of foreign [volcanic] series.
La fin de la nappe de Morcles dans le massif du Haut-Giffre

Nouvelles observations stratigraphiques sur le Cretace superieur du synclinal de Glandage-Creyers (Drome); repercussions paleogeographiques
Authors: Porthault Bernard
Published: March 2020

New paleontologic data, especially the discovery of Globotruncana concavata (foraminifer) and an Inoceramus (I. sp. ex gr. muelleri) in the gray-blue upper Cretaceous limestones of Glandage-Creyers (Drome, French Prealps), indicate that the limestones are essentially Santonian, possibly extending upward into the lower Campanian. The underlying Gas conglomeratic complex is now assigned to the upper Turonian and, at the top, to the Coniacian. The Gas complex consists of two conglomerate layers separated by sandy limestones. Thus the so-called pre-Senonian orogeny apparently took place in at least two phases, one early Turonian (pre-Senonian), the other late Coniacian (early Senonian). The Coniacian, not the Turonian, is the major phase.
Etude tectonique et morphologique de la vallee du Loup, entre Le Foulon et Courmes (Alpes-Maritimes)
Authors: Rousset Claude
Published: March 2020

Between Le Foulon and Courmes (Alpes-Maritimes, southeast France) the Loup river flows south-southeast. On the east side of the river, imbricate structures overthrust to the southwest are cut by northeast-southwest-trending faults. The rocks of the west bank are folded but much simpler in structure. The highly fractured nature of the eastern part of the area is believed to be the result of overthrusting onto a topography of high relief. The morphology and evolution of the Loup valley are described, including successive phases of karst formation, glaciation, and renewed downcutting.

Published: March 2020

The Paleozoic formations of the Adrar are divided into three parts, from base to top: the Agueni sandstone-quartzites, the Azougui shales, and the Foum Chor sandstones. Recognition of a strong erosional break between the middle and upper units permits definition of the Char group, including the lower and middle units which are between the major Precambrian unconformity and the discordance described here.
Observations geologiques en Sierra de Lujar (cordilleres Betiques internes, Espagne)

Published: March 2020

The Sierra de Lujar is composed of Triassic sedimentary rocks, mostly limestones and dolomites, in a reversed series. This unit seems to be the inverted flank of a recumbent fold of which the Lanjaron nappe is the normal flank, the fold being inclined toward the inner zones of the range. A lead deposit is associated with the carbonate rocks. It is of the stratiform type and appears to be related to a shoal zone that existed during the sedimentation of the ore host rock, and perhaps also to reworking and concentration of the latter, in which case it would be synsedimentary. These Triassic shoals, which have probably shifted somewhat, lie parallel to the northeast-southwest direction of the minor alpine (Cenozoic) folds that make up the Sierra. These minor folds are themselves parallel to the general alignment of the range.
Etude stratigraphique et tectonique des formations dolomitiques de la zone centrale de la chaine de l'Etoile, au nord de Marseille
Authors: Guieu Gerard
Published: March 2020

In the central zone of the Etoile range, north of Marseilles (southern France), a thick mass of dolomite (800 m), up to now considered upper Jurassic, actually comprises five formations: the Jurassic middle and upper Kimmeridgian and Portlandian, and the Cretaceous Valanginian and Hauterivian. The age of the formations has been determined on the basis of fossils (those not obliterated by dolomitization) and marker horizons, as well as by lateral tracing into well-dated units. Breccias and silicified horizons were examined. The Etoile dolomites were deposited in a basin of hypersedimentation bordered by thin limestone facies. A close analogy exists between the series studied in Etoile and correlative dolomitic sequences of the Marseilles region (in particular of Carpiagne and Sainte-Baume).
Contribution a l'etude du Quaternaire des Idjibitene et de la bordure meridionale de l'Adrar (El Gletat, Mauritanie)
Authors: Taieb Maurice
Published: March 2020

Two morphologically different regions are distinguished in the Quaternary of the Idjibitene mountains and along the southern border of the Adrar (El Gletat, Mauritania). Along the south and southwest border of the Adrar, deposits resulting from slope erosion are observed; to the south, dune structures and lake formations with white sands, brown sands, rare ferruginous crusts, and sand cemented by calcite (tarous) are seen. By observation of the terrain, collection of in place Acheulean industries, and study of the sands (granulometric and morphometric) it has been possible to reach an understanding of the stratigraphy. A chronology of Quaternary deposits of the Idjibitene is proposed. Close analogies with the Quaternary formations of Majabat are established.
Precisions sur le volcanisme acide dinantien a l'ouest de la butte Saint-Michel (region de Saint-Martin-des-Pres, Cotes-du-Nord)
Authors: Sagon Jean Paul
Published: March 2020

To the south of Saint-Martin-des-Pres (Cotes-du-Nord) [France], the author has discovered important acid volcanism, composed of rhyolites and potassic tuffs. The K 2 O contents are very high, above 8 percent. These rocks were emplaced at the beginning of the Dinantian [Carboniferous] and are superposed on the 'dolerites of Bosmeleac.'
Quelques observations morphologiques et sedimentologiques effectuees a bord du bathyscaphe 'Archimede' au large des Maures et de l'Esterel
Authors: Bellaiche Gilbert , Pautot Guy
Published: March 2020

This submarine study constitutes a verification in place of data obtained from the surface by current oceanographic methods, such as bathymetric measurements, cores, and drag samples. It poses various problems, such as the origin of the adherence of mud to steeply inclined surfaces and the difficulty of interpreting morphologic sections.
A propos de l'age des calcaires senoniens mineralises de Tunisie septentrionale
Authors: Kujawski H.
Published: March 2020

Lead-zinc deposits occur in Tunisia in a Senonian limestone formerly assigned to the Campanian. The close of the Cretaceous is represented by two limestone units, however, one Campanian and the other Maestrichtian. Microfaunal evidence indicates that the commercially significant ores occur in the Maestrichtian limestone.
Phacopidella (Prephacopidella) hupei nov. sp., nouveau trilobite de l'Ordovicien du Finistere
Authors: Nion Joel , Henry Jean Louis
Published: March 2020

A new trilobite species discovered in Llandeilian shales of the Crozon peninsula is discussed; this species, at the present state of knowledge, is the oldest known representative of the subgenus Phacopidella (Prephacopidella), first described in 1963 by J. Destombes from the Ashgillian of the Anti-Atlas (Morocco) and up to now unknown in Brittany.
Chaines andines et chaines alpines; regard sur la geologie de la Cordillere des Andes au parallele de l'Argentine moyenne
Authors: Aubouin Jean , Borrello Angel V.
Published: March 2020

The tectonic evolution of the Andes was generally contemporaneous with the Alpine orogeny (Mesozoic-Tertiary). Pre-Andean tectonic cycles (Hercynian) involved Infracambrian and Paleozoic sediments. Comparison of the Andean cycle with the Alpine cycle shows a similar evolution in three major periods: a Mesozoic period characterized by strong compressional movements during which the thick sediments of the Chilean slopes were thrust over the relatively thin sediments of the Argentine slopes; an Eocene-Oligocene-Miocene period characterized by the deformation of terrigenous formations as a result of andesitic volcanism and reverse faulting; and a Plio-Quaternary period marked by basalt flows and the accumulation of thick terrigenous sediments in faulted, deformed basins. The absence of flysch deposits, ophiolites, major thrust sheets, and widespread metamorphism in the Andes, however, distinguishes them from the Alpine ranges. Thus, two main types of pericratonic mountain ranges (as opposed to intracratonic ranges) should be differentiated: precursory (or Andean) ranges developed on the periphery of continents but within their margins and geosynclinal (or Alpine) ranges part of which are extracratonic.
Etude des terrains eocenes et oligocenes du bassin liguro-piemontais dans la region de San Sebastiano Curone-Varzi (Apennin septentrional)
Authors: Labesse Bernard
Published: March 2020

The lower Tertiary formations of the Liguria-Piedmont basin (Italy) are characterized by epicontinental detrital deposits rich in clastic material. The biofacies generally have a littoral character. The general abundance of planktonic microfaunas suggests the existence of an open sea. Lower and middle Eocene sediments are absent in the area. The Oligocene was apparently affected by intense periods of erosion as indicated by local conglomeratic intervals. Variations in thickness of the Eocene-Oligocene section are related to submarine morphology and the hydrographic regime of the continent. Major tectonic disturbances occurred in the lower Miocene.
