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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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 &lt;sub&gt;2&lt;/sub&gt; O &lt;sub&gt;5&lt;/sub&gt; 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

Abstract
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

Abstract
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

Abstract
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.

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

Abstract
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).

Sur l'origine periglaciaire de petits lacs du massif d'Aubrac
Authors: Rousset Claude 
Published: March 2020

Abstract
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

Abstract
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).
Le 'volcan' de Beaulieu, pres Rognes (Bouches-du-Rhone)
Authors: Gueirard Simonne 
Published: March 2020

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract
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.

Published: March 2020

Abstract
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

Abstract
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.

Abstract
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

Abstract
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.
