Considerations sur la chronologie du Quaternaire saharien
Authors: Alimen H. 
Published: March 2020

Abstract
Recent research in the Sahara is assembled and studied for the purpose of correlating the Quaternary deposits of that region with European glacial chronology. For this reason the Sahara sedimentary series and the Pyrenean fluvioglacial phases are compared. Absolute dates obtained from equatorial, north-tropical, and Mediterranean Africa are presented in a chart which includes prehistoric industries and the glacial chronology of France and central Europe. Deposition of the sediments of the last sedimentary cycle in north Africa began approximately 20,000-30,000 yrs. B.P. (Paudorf interstade). Pollen from the Mousterian-Aterian sediments at Hoggar seem to indicate a subhumid to humid climate for the southern Sahara. The same seems to be true in the northwestern Sahara. Radiocarbon dates correlate the European Wuerm III with the Saharan humid phase, and the period of maximum humidity in the Neolithic of the southern Sahara with the renewal of humid conditions in Europe during the Atlantic and Subboreal epochs. The data assembled reveal a similar pluvioglacial period and climatic succession in south-tropical and equatorial Africa. The three tables included illustrate the proposed correlations between the different African regions, France, and central Europe.
Degre d'evolution des sediments neolithiques et post-neolithiques du Touat. Comparaison avec la Saoura
Authors: Conrad Georges 
Published: March 2020

Abstract
Quaternary formations exposed at Bou Ali (western Sahara) are described in conjunction with a discussion of the evolution of the Neolithic deposits at Saoura and Touat. The deposits are primarily alternating beds of swamp paleosols and tuffs separated from the underlying coarse continental sandstone by a conglomerate. Two independent sedimentary cycles are overlain and thus preserved by a sandstone crust. The lower cycle includes poorly consolidated conglomerate, coarse red-stained sandstone, and argillaceous limestone. The upper cycle includes a succession of limestone tufa and swamp paleosols separated by fine sands. A hematized tree trunk, reported from Quaternary deposits near Ait el Messaoud, is proof of the arborescent flora of the recent Quaternary. The presence of hematite in such recent deposits is explained by the epigenesis of iron sulfide. Cross sections and cumulative granulometric curves are included along with tables comparing the compositions of the swamp paleosols and the red-stained horizons.
Les transgressions cretacees sur le massif d'Oroz-Betelu (Navarre espagnole)
Authors: Ciry Raymond , Amiot Maurice , Feuillee Pierre 
Published: March 2020

Abstract
The Oroz-Betelu massif is a large anticline composed of Paleozoic and Triassic rocks, surrounded by Cretaceous and Tertiary strata. Study of the biofacies and lithofacies shows that this structure was an emerged zone during the Cenomanian. It was invaded by the Santonian Lacazines sea and oscillations brought about a partial emergence at the end of the Santonian or at the beginning of the Campanian. This was followed by the deposition of a flysch facies at the end of the Campanian. A marine regime continued throughout the remainder of the upper Cretaceous.
Observations nouvelles sur la region du Cap-d'Ail (Alpes-Maritimes)
Authors: Bourcart Jacques , Damiani Lucien , Vernet J. , Le Calvez Yolande 
Published: March 2020

Abstract
Recent drilling in the eastern part of the Cap d'Ail region and in neighboring Monaco has furnished information on the strata underlying the Quaternary cover. Local unconformities appear to exist in the Pliocene-Miocene section and thrusting has resulted in complex relationships. Jurassic rocks have been thrust over Cretaceous, which in turn, are overthrust on lower Miocene volcanic tuffs.
Lithologie des calcaires a Hippurites au plateau du Camp (Var)
Authors: Blanc Jean J. 
Published: March 2020

Abstract
Upper Angoumian (upper Turonian: upper Cretaceous) sedimentation in the Camp plateau area of the Beausset basin of southern France occurred in an area of exclusively calcareous deposition, as contrasted with the terrigenous deltaic sedimentation in the La Ciotat and Soubeyran areas; but two antagonistic types of deposition occurred concurrently in the area. Colonies of Hippurites and other bioconstructive organisms developed limestone lentils, and waves and currents eroded the limestone masses into biodetrital calcarenite deposits in which no trace of bioherm structure is seen.

A new species described from the middle Stephanian in southwest France is excellently preserved. Its characteristics can be compared to Sphenopteris lenis Zeiller and to Sphenopteris matheti Zeiller from the middle Stephanian of the Loire.
Contribution a l'etude du Bedoulien entre la Bedoule et Cassis (Bouches-du-Rhone)
Authors: Humbert Simone 
Published: March 2020

Abstract
Stratigraphic study of the Bedoulian (Aptian, Cretaceous) units southeast of Marseilles (France) on the southern slope of the Saint-Cyr-Carpiagne chain reveals rapid lateral variation of facies between Cassis and Bedoule. The five formations previously described from the area are revised on the basis of more detailed information. The first formation, a calcarenite with rudistids and gastropods, is uniform between the two localities and represents the Urgonian-Bedoulian transition. The second and third formations, beige or gray limestones, sometimes marly, with abundant ammonites--Deshayesites, Parahoplites--vary considerably in thickness. The marly limestones of the fourth formation remain relatively uniform, while the fifth formation disappears west of Saint-Jean. The fauna collected from these units is the classic Bedoulian assemblage. The maximum thickness of the Bedoulian occurs at Comte indicating major subsidence during that time. The Bedoulian aureole is affected by two series of fractures, one perpendicular to the direction of the bedding and the other parallel to it.
La microfaune de foraminiferes des gisements de Salles (Gironde)
Authors: Julius Charles 
Published: March 2020

Abstract
A detailed study of the foraminifera collected from Moulin Debat, Champ de Minoy and the Chateau quarry at Salles (Gironde, France) shows that the microfauna is of Helvetian age. It is characterized by the abundance of Orbulina and by the degree of evolution attained in the ornamentation of the Nonionidae. Study of the sedimentation indicates that the microfauna were deposited in a warm moderately shallow sea which was relatively closed to oceanic influences. Sixty-two species belonging to 36 genera were identified from the localities and are listed in a table with their stratigraphic distribution.
Note sur les Thecideidae (brachiopodes) jurassiques
Authors: Pajaud Daniel 
Published: March 2020

Abstract
Jurassic brachiopod species belonging to the Thecideidae are listed from the western border of the Franco-English basin (Normandy and southern England). Separate lists are given for species confined to the Lias, the Dogger, and the Malm. A new genus, Elliottina, is described which includes E. styliformis n. sp. as the type species. Davidsonella truncata n. sp. and Eudesella? romani n. sp. are also described.
Etude tectonique du secteur Pradoluengo-Alarcia, Sierra de la Demanda (chaines iberiques, Espagne)
Authors: Colchen Michel 
Published: March 2020

Abstract
A tectonic study of the area northwest of Sierra de la Demanda (Spain) revealed Tertiary orogenic phases represented by overlaps and overturnings. Towards the northern border, the Cambrian overrides Carboniferous, Triassic and Jurassic formations; the Carboniferous-Triassic units appear overturned under the Cambrian; and the Jurassic formations are affected locally by a system of dislodged slices of nappes associated with imbricate basement rocks. Two major directions of deformation suggest the presence of two successive orogenic phases. The first phase, older than the Oligocene conglomerates, folded the units above the basement in a NW-SE direction, parallel to the north oriented horst in the basement complex. In the post-Oligocene phase NE-SW imbrication affected the conglomerates as well as the basement and overlying units.
Sur la datation des breches de la montagne Sainte-Victoire pres d'Aix-en-Provence
Authors: Touraine Fernand 
Published: March 2020

Abstract
Breccias in Sainte-Victoire mountain have been considered upper Cretaceous because of their stratigraphic position and the presence of dinosaur eggs. Other nearby breccias are considered Montian (lower Eocene). The supposed upper Cretaceous breccias are displaced from the principal masses by faulting but are the same Montian formation and age.
Sur les couches comprises entre le Wenlockien et le Siegenien dans le Cotentin
Authors: Robardet Michel 
Published: March 2020

Abstract
The beds making up the comprehensive series 'd &lt;sup&gt;1&lt;/sup&gt; s &lt;sup&gt;4&lt;/sup&gt; ' on the second edition of the Saint Lo sheet of the 1:80,000 geologic map are undifferentiated Silurian-Devonian. Poor outcrops and inadequate paleontologic evidence have prevented correlation of these beds or determination of the Silurian-Devonian contact. In the Saint Sauveur-le-Vicomte area, the beds include fossiliferous strata containing Wenlockian (Silurian) graptolites overlain by beds with fossils transitional between Gedinnian and Siegenian, thus placing the contact in that area. Outcrops of these beds are more extensive than the map shows, hence the map boundaries of the May sandstone 's &lt;sup&gt;2b&lt;/sup&gt; ' require revision, and the outcrops of kersantite are considerably smaller than indicated.

Les bauxites de la province dinarique (Yougoslavie)
Authors: Grubic Alexandre 
Published: March 2020

Abstract
The Dinaric karst of Yugoslavia has many deposits of red and white bauxites ranging in age from Triassic to Tertiary. Some deposits in Slovenia and Bosnia are of undetermined age. The number of bauxite beds at different stratigraphic horizons in each locality was determined by the number of periods of emergence. The Ljesev stup-Bijele poljane and Budos areas remained emergent a long time, and have thick deposits. Several horizons of bauxite were formed in Dalmatia, Herzegovina, and Vojnik-Prekornica. A brief emergence resulted in single bauxite deposits in Velebit, Lika, Istria, Grmec, and Bespelj.

Abstract
Two species of Devonian trilobites, Unguliproetus andegavensis n. sp. and Unguliproetus erbrayi n. sp., from the Emsian (uppermost lower Devonian) of the Armorican massif of northwestern France resemble in some respects the Tropidocoryphinae.
Nouvelles donnees sur les spilites de la serie de Moglio; nappe du flysch a helminthoides des Alpes maritimes franco-italiennes
Authors: Haccard Daniel 
Published: March 2020

Abstract
Spilites are interbedded in the Moglio series (Cretaceous) at the base of the helminthoid flysch in the Viozene area, Italy. The Moglio contains microgranular quartzite elements and small chlorite balls indicative of an ancient microbreccia or tuff. At their contacts with the sedimentary rocks, the spilites are truncated or take on the microstratification of the sediments. Petrographic study of the spilites shows them to have microlitic structure with plagioclase microlites, small phenocrysts, and calcite globules. The spilites are considered an ancient andesite, almost a diabase. The evidence of rapid crystallization, the structure and the calcite-filled vacuoles suggest submarine extrusion during deposition of the Moglio sediments.
Observations sur les series marno-micacees du synclinal du Reposoir (Haute-Savoie)
Authors: Charollais J. , Rosset Jean 
Published: March 2020

Abstract
The Reposoir syncline (France) lies between the folded strata of the Aravis mountains and the Bargy anticline in the Bornes region. The Annes outlier, in the syncline, is the only remaining evidence of the allochthonous block overthrust on the Aravis. The boundaries between the tectonic units are based on the position of the marly-micaceous series, containing sandy beds with volcanic debris. A comparative petrographic and sedimentologic study of this series in the Aravis and Bargy areas and in the Annes outlier emphasizes the variation in the detrital sediments--silts, sandstone and volcanic graywacke, and conglomerate. Stratigraphic profiles have been constructed from eleven outcrop areas of the marly-micaceous series in the Reposoir syncline. Organic remains in the series are dated as Priabonian (Eocene) and lower Oligocene. The Annes outlier contains lenses of Senonian (upper Cretaceous) sediments.
L'evolution tectonique post-hercynienne de la bordure mesozoique des Cevennes meridionales entre Ales et Ganges
Authors: Seguret Michel , Proust Francois 
Published: March 2020

Abstract
The southeast edge of the Central Massif, between the Rhone and Herault valleys (France), is an area of Mesozoic rocks cut by a NE-SW fault system. Movement along the faults has been recurrent and from the Triassic through the succeeding Mesozoic, uplift and downwarp resulted in local basins and troughs accumulating distinct sedimentary suites. Intense compressive movements associated with the Pyrenean revolution during the late Eocene produced complex folds and overthrusts imposed upon the normal fault system. Continuation of the activity contributed to the complexity of the structures during the Oligocene. No evidence was found, during recent studies, to support the theory of allochthonous movements during the Oligocene.
Presence d'Arenagula kerfornei (Allix), foraminifere 'biarritzien', a la partie terminale du Lutetien superieur de Foulangues (Oise)
Authors: Cavelier Claude , Le Calvez Y. 
Published: March 2020

Abstract
Identification of the foraminifera Arenagula kerfornei, characteristic of the upper Lutetian (Eocene) in the Paris basin, in the Biarritzian shelly sands, located between Tillet and Foulangues, allows the placement of the Biarritzian within the Nummulites varialarius biozone, which corresponds to the uppermost Lutetian and represents the beds just below the basal Auversian.
Donnees nouvelles sur la stratigraphie et les facies du Montien et du Sparnacien inferieur a Paris
Authors: Duronsoy Claude 
Published: March 2020

Abstract
A composite lowermost Tertiary section based on lithologic and paleontologic data from three cores drilled near Paris, France, shows the Montian beginning with a bed which is transgressive on the Campanian chalk. Marked variations in thickness of the Montian beds and the partial disappearance of the upper horizons confirm the existence of a pre-Sparnacian period of erosion. The Meudon conglomerate and the overlying lignitic sands at the base of the Sparnacian are succeeded by a series of sands and shales. The Auteuil sands were deposited in deep gullies cut in shales. The thicknesses of the Montian and Sparnacian facies in the cores are compared in a chart.
Sedimentation microcyclothemique avec croutes zonaires a algues dans le calcaire de Beauce de Chauffour-Etrechy (Seine-et-Oise)
Authors: Freytet Pierre 
Published: March 2020

Abstract
The Chattian Beauce de Chauffour limestone (France), is represented by a series of microcyclothems averaging 30-35 cm in thickness. The rhythmic series includes lacustrine limestone facies--breccias, marls, coquina--and a zoned crust of alternating thin dark and light beds containing algal filaments. This type of sedimentation is the product of a relatively arid region, with intermittent wet and dry periods.
Observations sur les mineralisations de l'arkose' d'Alencon (Orne)
Authors: Lemaitre Helene 
Published: March 2020

Abstract
The upper Aalenian (Jurassic) Alencon arkose of the Orne region, France, contains, in a limited area where the substratum is a two-mica granite, different mineralization zones--silica, barite, pyrite, galena, sphalerite, and fluorite. The Hercynian (Paleozoic) age of the massif excludes the hypothesis of a hydrothermal origin for the mineralized zones. The theory of a sedimentary origin does not explain certain characteristics of the deposit, such as concentration of the mineralization within a limited geographic area and the abundance of silica. Origin is therefore attributed to the activity of thermal spring waters.
Series stratigraphiques et paleogeographie du Cretace superieur dans la region de Lourdes
Authors: Capdecomme Hubert , Deloffre R. , Henry Jacques , Villanova Michel 
Published: March 2020

Abstract
Stratigraphic and paleogeographic data indicate that a zone of the northern Pyrenees was extensively covered by flysch deposits during the upper Cretaceous. The region north of Lourdes has been placed in the Cenomanian-Turonian on the basis of microfauna, and the area to the south is considered Senonian. The two areas were internally folded and although separated by an intermediate cordillera were part of an orogenic unit whose history of subsidence, anticlinal folding, emergence and destruction of cordilleras was associated with the tectonic evolution of the regional geosyncline.

Un element externe de la zone du Pinde; la serie d'Ethia (Crete, Grece)
Authors: Aubouin Jean , Dercourt Jean , Neumann M. , Sigal Jacques 
Published: March 2020

Abstract
The Ethia series of the Pindic facies in Crete (Greece) includes about 30 m of Eocene transitional limestones at the top. The flysch facies overlies these limestones. Thus the Ethia series, in the paleogeography of the Hellenides, is on the outer margin of the Pindus trough, in the zone transitional to the Gavrovo-Tripolitsa ridge.
Sur la limite entre la partie inferieure ('Paleocene') et la partie moyenne ('Eocene') du Paleogene
Authors: Szoets Endre 
Published: March 2020

Abstract
The Paleocene-Eocene boundary is defined on the basis of planktonic foraminifera. The Globorotalia parva zone, the uppermost Paleocene zone, represents the Thanetian, at least in part, or Landenian stage, including the lower part of the Ilerdian stage of Hottinger and Schaub (1960). The G. subbotinae zone, the lowermost Eocene zone, is equivalent to the lower part of the Ypresian, Sparnacian, or Londonian stage, which includes the middle and upper parts of the Ilerdian stage.
Essai de classement d'echantillons de stromatolites des series precambriennes de l'Ahaggar occidental
Authors: Bertrand-Sarfati Janine 
Published: March 2020

Abstract
Specimens of stromatolites from the Precambrian series of the western Ahaggar mountains in the central Sahara of southern Algeria have been classified and studied. 'Conophyton,' bedded reef types, and branching types have been distinguished in the material from different localities. Study of the latter type permits establishment of stratigraphic sections similar to those defined in the Russian Riphean (Precambrian).
Etude des keratophyres de la region de Redon (Paleozoique inferieur du Massif armoricain)
Authors: Boyer Claude 
Published: March 2020

Abstract
At the top of the Cambrian in the Redon region (Armorican massif, France) are indications of acidic volcanism of the quartz keratophyre type, with a low temperature mineral paragenesis. Microlitic and semiglassy flows and a granophyre-filled pipe have been identified. The petrology, mineralogy, and chemistry of the rocks show that the volcanism took place under aerial, continental conditions, contradicting the classical idea that albitophyric extrusions are submarine and of geosynclinal type. The lavas evolved from an early hypersodic phase to a late hyperpotassic extreme, with an intermediate sodi-potassic stage. The flows may have come from a single homogeneous sodi-potassic magma or from several heterogeneous magmas at depth.
Sur une nouvelle espece de coniferale jurassique provenant des 'terres noires' du bassin de la Durance (Dadoxylon alpinum n. sp.)
Authors: Lemoigne Yves 
Published: March 2020

Abstract
The study of the components of a breccia coming from the base of the black earths [middle Jurassic, French Alps] of the Barcillonnette wedge (Hautes-Alpes) has enabled the observation of fragments of carbonized wood whose characteristics have led to the description of a new conifer of mixed gymnosperm structure and whose Jurassic age has been determinable.
Le Jurassique et le Neocomien du mont Sacon (Pyrenees centrales)
Authors: Delfaud Jean 
Published: March 2020

Abstract
In the Mont Sacon series (central French Pyrenees) the stratigraphic succession from the Jurassic to the Neocomian (lower Cretaceous) can be observed. Four groups are distinguished: the Liassic, the middle and upper Jurassic, the terminal Jurassic, and the Neocomian. By means of the microfauna, these strata are correlated with sequences in the Pyrenees and the Aquitaine basin. Several important sedimentary breaks--in the lower Bathonian, Oxfordian, Sequanian, and the base of the upper Portlandian (Jurassic), and the basal Valanginian and upper Neocomian (Cretaceous)--are evidence of changes in sedimentary environment at least partly due to movements of the basement.
