Authors: Basse Eliane , Alloiteau James , Karrenberg Herbert , Lefranc Jean Phillipe , Lehman Jean Pierre 
Published: June 2020

Abstract
Gives the stratigraphy and inferred history of the Mesozoic sediments underlying the Nubian sandstone in Yemen and describes faunas from four zones, including a new Jurassic fish (Pleuropholis bassei), Jurassic invertebrates (including the new pelecypod Lopha karrenbergi, the new gastropod Cryptoplocus yemenensis, and three new corals, Favitopsis harrensis n.sp., Microphyllastraea karrenbergi n.g. n.sp., and Plesiophyllum harrensis n.g. n.sp.), and gastropods from the Nubian sandstone.
Nouvelles considerations sur la tectonique de l'Anatolie (Turquie, Asie Mineure)
Authors: Pinar Nuriye , Lahn Ervin 
Published: June 2020

Abstract
The folded regions of northern and southern Anatolia, Turkey, consist of Alpine structures involving the same stratigraphic sequence and manner of deformation; they are fundamentally similar to the European Alps. Post-Alpine epeirogenic structures, with which the seismic activity and late Tertiary and Quaternary volcanism of the region are related, are particularly well developed in Anatolia, often to an extent that orogenic structures are obscured.
Quelques formes nouvelles de polypiers et de foraminiferes de l'Oligocene et du Miocene du NW de la Grece

Abstract
An account of the stratigraphy (by Brunn), corals (by Chevalier), and the microfauna (by Marie) of the thick sequence of posttectonic detrital Oligocene and Miocene deposits of northwestern Greece. Descriptions of the corals Favites oligocenica n.sp., Favia pentalofonensis n.sp., Pindosmilia brunni n.g. n.sp., and Siderofungia graeciae n.sp., and the foraminifer Austrotrillina brunni n.sp. are included.
Remarques sur la correlation des unites penniques externes entre la Savoie et le Valais et sur l'origine des nappes prealpines
Authors: Trumpy Rodolphe 
Published: June 2020

Abstract
Discusses the tectonic relationships of Pennine structural elements and the sources of Prealpine nappes in the Savoy (France)-Valais (Switzerland) region. The source of the central Prealpine nappe seems to have been in the Subbrianconnais-outer Brianconnais zone. Plastic elements were thrust along Carnic (Triassic) gypsum beds, whereas rigid elements were dislocated along Werfenian (Triassic) gypsum. Between the Ultradauphinois- Ultrahelvetic and the Subbrianconnais zones, north of the Arc river, lies the Valais zone which had an independent paleogeographic history. The source of the upper Prealpine nappes is still uncertain.
Sur quelques microorganismes des silex cretaces du Magdalenien de Saint-Amand (Cher)
Authors: Valensi Lionel 
Published: June 2020

Abstract
Describes several hystrichospherids from prehistoric (Magdalenian) artifacts found near Saint-Amand, Cher, France. The microfossils indicate that the flint from which the artifacts were made is Cretaceous in age. The following species are new: Hystrichosphaeridium rhopalophorum, H. tridactylites, H. huguonioti, and Micrhystridium fucosum.
Description de quelques bryozoaires des calcaires de Montainville et de Vigny (Seine-et-Oise)
Authors: Balavoine Pierre 
Published: June 2020

Abstract
Describes bryozoans from basal Eocene limestones of Montainville and Vigny, Seine-et-Oise, France, including the new species Membraniporidra montainvillensis, Steraechmella vignyensis, and Trypostega flabellata.
L'autochtone sud-tellien; a propos d'hypotheses recentes
Authors: Calembert Leon 
Published: June 2020

Abstract
Concludes that the Jurassic and Cretaceous massifs of the southern Tell region, Algeria, are autochthonous masses which constitute an independent unit whose development can be explained by gravitational flow. The concept of a zone of overthrust in the Paleozoic basement is superfluous and a probable source of confusion to future investigations.
Sur la radioactivite de sediments actuels et recents de la cote mediterraneenne; etude particuliere du golfe du Lion; interpretation sedimentologique [with discussion]
Authors: Riviere Andre 
Published: June 2020

Abstract
Gamma-ray measurements on modern beach sands of the Lions gulf, France, can be interpreted as a function of their granulometric and mineralogic composition; thus radioactivity measurements provide a new sedimentologic tool. The procedure is described, and problems posed by certain aberrant measurements are discussed.
Sur quelques echinides fossiles etrangers
Authors: Jeannet Alphonse 
Published: June 2020

Abstract
Three echinoids are described--Tithonia arctica n.sp. from the Valanginian (Cretaceous) of eastern Greenland, Leiocidaris thiebaudi n.sp. from the Albian (Cretaceous) of Catunbela near Lobito, Angola, and Parasalenia cf. poehlii from the Pliocene of Erromango in the New Hebrides (southwest Pacific).
Etude geologique, mineralogique et structurale des gisements et minerais de chrome du massif de Tiebaghi (Nouvelle- Caledonie)
Authors: Caillere Simonne , Kraut F. , Routhier P. 
Published: June 2020

Abstract
Field and laboratory study of the chrome ores of the Tiebaghi massif New Caledonia shows that they are really chromopicotites, that the gangue was originally a dunite, and that segregation of the chromite was an early process which was contemporaneous with the differentiation into layers of the surrounding harzburgites. The peridotite was at least in part later than the chromite; serpentinization was definitely later. For mining purposes the banding of the peridotites can be taken as a guide to the mineralization. Microscopic structures in the chromiferous bodies are shown to be related to large-scale geologic features.
Facies et nature de la sedimentation dans les bassins de la Loukouni et du Djoue (region du Niari, A.E.F.)
Authors: Riedel Alfredo 
Published: June 2020

Abstract
The numerous and varied facies in the "Schisto-calcaire" and the "Schisto-greseux" series in the Loukouni and Djoue river basins in the Niari region, French Equatorial Africa, are analyzed and the broad regional stages established. The Schisto-calcaire (mainly more or less magnesian limestones and marls) is divided into six stages representing transition from deposition in an epineritic shelf environment toward calcareous sedimentation in shallow water. Correlations can be drawn with similar beds in the Belgian Congo. The Schisto- greseux (mainly arkosic sandstone) is divided into the M'Pioka and Inkisi series. The series are characterized by relatively uniform facies which indicate deposition in a transitional (fluvial-lagoonal-littoral) environment within an intracratonic basin.
Le substratum organique dans les depots calcaires, sa signification
Authors: Nesteroff Wladimir D. 
Published: June 2020

Abstract
From the residues left after decalcification, it is possible in most cases to determine whether a limestone is biogenic in origin or the product of physicochemical processes. The bacterial origin of the cementing material of beach rock in the Red Sea region and of Tenaera-bearing structures of the French Mediterranean coast can be demonstrated.
Les nappes phreatiques et artesiennes du Jura septentrional (dept du Doubs); leurs relations avec les reseaux karstiques
Authors: Glangeaud Louis , Francois Solange , Perrenoud Marie Jeanne , Pezard Robert , Toitot Michel 
Published: June 2020

Abstract
Discusses the exploration and exploitation of ground-water zones in the northern Jura region, France. Phreatic waters occur in Tertiary and Quaternary beds, and artesian aquifers in Mesozoic formations. The source, circulation, and recovery of waters in the karst and overlying alluvial deposits are treated in some detail.

Abstract
Describes underwater seismic surveys in the Algiers bay region. Two layers, thickening toward the north-northeast, overlie the metamorphic basement--a layer of Recent sediments underlain by a layer of material considered lower Miocene in age.
Sur les Permosoma du Djebel Tebaga (Permien de l'extreme-sud tunisien)
Authors: Termier Henri , Termier G. 
Published: June 2020

Abstract
Discusses the coral genus Permosoma in the light of several specimens collected from Permian deposits of the Tebaga massif in southernmost Tunisia. The openings are true opercula, resembling those of Khmeria problematica from Cambodia. Both are difficult to classify on the basis of present knowledge.
Observations sur les niveaux a charophytes de l'Aptien des monts des Oulad-Nail (Atlas saharien, Algerie)
Authors: Emberger Jacques , Magne J.  
Published: June 2020

Abstract
With slow retreat of the Aptian sea from the Oulad Naiel mountain region, Algeria, lagoonal- marine beds graded into continental Albian (Cretaceous) deposits. The transitional zone contains remains of charophytes; these plants, considered lacustrine, are here associated with foraminifers, showing that they had become adapted to a brackish-water environment like the modern characeans. The marshy emergent coast of that time was comparable to the Cape Hatteras region of today. The charophyte flora is described.
Correlation chronologique des phenomenes geodynamiques dans les Alpes, l'Apennin et l'Atlas nord-africain
Authors: Glangeaud Louis 
Published: June 2020

Abstract
A new concept of the evolution of the entire Alpine system is presented, based on a comparative study of chronodiagrams for the ranges bordering the Mediterranean both in Europe and Africa. The relation of post-paroxysmal (Miocene) nappes and Plio-Quaternary deformation to the main orogeny, the mechanism of the Mediterranean tectorogen, and some seeming anomalies are explained. A selected bibliography is appended.
Stromatorhiza Bakalow, stromatoporoide du Jurassique superieur
Authors: Hudson Robert George Spencer 
Published: June 2020

Abstract
Reexamination of the lectotype of Thamnaraea? granulosa, genotype of Stromatorhiza, shows it to be a stromatoporoid. Astrostylopsis is considered to be a more recent synonym of Stromatorhiza. The genus is established as the type of a new family, the Stromatorhizidae, to which also belong the genus Trupetostromaria and certain Liassic forms classified with the spongiomorphs by LeMaitre.
Note preliminaire sur le niveau marin de 3 m et les series dunaires de l'extreme sud de Madagascar
Authors: Battistini Rene 
Published: June 2020

Abstract
A preliminary report on Quaternary shore lines and dune systems of the extreme southern part of Madagascar. Consolidated beach deposits three meters above present sea level are attributed to a stillstand (here named the Karimbolian) which occurred prior to the pre-Flandrian regression. This three-meter level acts as a marker zone for identifying periods of dune formation. Present knowledge of the Quaternary history of the region is summed up in a table correlating climates, cycles of erosion and continental sedimentation, shore lines, and phases of dune formation.
Essai de correlations stratigraphiques en Grece occidentale
Authors: Aubouin Jean 
Published: June 2020

Abstract
Describes the stratigraphic series of each of the structural elements of western Greece. From west to east these elements comprise the Paxos zone (marginal to the stable Apulian block), the Ionian trough, the Gavrovo fold, the Pindus trough, and the sub-Pelagonian zone (marginal to the Pelagonian ridge). Orogenic activity began in lower Cretaceous time in the fundamentally unstable Pelagonian ridge and progressed westward toward the continental (cratonic) Apulian block. The Pindus trough was a eugeosyncline (with ophiolites), the Ionian trough a miogeosyncline (without ophiolites); the Pelagonian and Gavrovo ridges are sialic.
Quelques problemes de paleogeographie alpine
Authors: Trumpy Rodolphe 
Published: June 2020

Abstract
A criticism of the theory of embryonic precursory folding in the Alps, based on some examples from Helvetic, Pennine, and Prealpine zones in Switzerland and Savoy, France. The importance of Mesozoic flexures and faults is stressed, as well as the absence of any indications of tangential crustal movements before the Cretaceous and the presence of evidence proving the instability of the paleogeographic elements of the Alpine zone. The thick masses of Alpine schists are not mainly "comprehensive series," but deposits accumulated rapidly in a relatively brief period of time. The essential characteristic of the Alpine geosyncline was mobility rather than subsidence.
Une serie subbrianconnaise typique; la serie de Piolit (Hautes-Alpes)
Authors: Latreille Michel 
Published: June 2020

Abstract
Detailed analysis of the Piolit series in the Piolit massif, Hautes-Alpes, France, a typical Subbrianconnais series, shows that in spite of continuous submergence, an important post- Oxfordian, pre-Tithonian (Jurassic) hiatus is present in the sequence. Berriasian strata identified in the sequence represent the first known occurrence in the intra-Alpine domain. The overlying beds are continuous but telescoped at the Infracretaceous-lower Cretaceous boundary. The late Cretaceous-lower Eocene beds correspond to a fine-grained flysch sediment. The Subbrianconnais Piolit series is distinct from the contiguous Ultradauphinois and Brianconnais zones to the west and east respectively.
Esquisse geologique de l'Arabie seoudite
Authors: Karpoff Roman 
Published: June 2020

Abstract
An outline of the geology of Saudi Arabia. The Precambrian basement consists of two distinct series. The Medina series, the older, includes rocks metamorphosed to different stages (sericite schists, gneisses, and migmatites), with numerous lava flows, particularly in the western part. Various granites and dike rocks intrude the Medina but not the Wadi Fatima series lying discordantly above it. The Wadi Fatima is folded and contains three local stromatolitic zones. The Paleozoic is represented in the north by rocks exhibiting a typical Saharan facies. Marine Muschelkalk (Triassic) beds and Jurassic formations (beginning with Toarcian) cover a large area. The most important Cretaceous transgression occurred in the Maestrichtian, when a gulf extended to the Djeddah region. The grabens of central Arabia appear to be related to the formation of the Red Sea depression during Mio-Pliocene time.
La peperite a ciment de diatomite de la montagne d'Andance (massif du Coiron, Ardeche)
Authors: Grangeon Pierre , Michel R. 
Published: June 2020

Abstract
Detailed petrographic study (with a chemical analysis) of the upper Miocene peperite forming the west slope of Andance mountain in the Coiron massif, Ardeche, France. The peperite was formed when a basaltic (basanitoid) lava was intruded into diatomaceous muds of a lava-dammed lake. The ensuing underwater eruption was accompanied by ejection of "intraformational" volcanic bombs.
Un profil des gres vosgiens le long de la vallee de la Meurthe
Authors: Clin Michel , Laugier R. , Millot G. 
Published: June 2020

Abstract
Closely spaced borings for ground water in the Meurthe valley between Baccarat and Luneville, France, show that the dip of the Vosgian sandstones (Triassic) is variable, a fact which is attributed to northeastsouthwest faults rather than to flexures. The water table in the sandstones is well protected from infiltration of saline water from overlying middle Muschelkalk (Triassic) beds; however, a periodic increase in salinity at Chenevieres may be due to leaching of a middle Muschelkalk bed.
Quelques resultats des sondages executes en Savoie par la Regie autonome des Petroles
Authors: Michel Pierre , Caillon G. 
Published: June 2020

Abstract
Presents the results of exploratory borings around two anticlines in Savoy, France (the Age and Gros Foug-Montagne des Princes massifs). Important stratigraphic information and precise structural data were obtained. Three types were distinguished among the oil indications--Molasse (Tertiary), both paraffinic and naphthenic; Urgonian (Cretaceous), slightly naphthenic; and Berriasian (Jurassic), paraffinic.
Micropaleontologie des silex du Grand Pressigny
Authors: Valensi Lionel 
Published: June 2020

Abstract
A description of the petrographic characteristics and microfauna of flints of the Grand Pressigny region, France. Similar flints have also been found as prehistoric implements in widely distant localities. Some of the yellow flints are exceptionally rich in Miliolidae. The microfauna confirms an upper Cretaceous age for the flints.
La "double faille de la Marne" [with discussion]
Authors: Stchepinsky Vladimir 
Published: June 2020

Abstract
Reports the results of a detailed study of the so-called double fault of the Marne, a north-south fault graben extending from the Saulx-Ornain valley region (Marne) in the north to Flammerecourt (Haute-Marne), France, in the south. North of the Paris-Strasbourg highway, the graben becomes a fault-zone depression more than five kilometers wide and convex toward the west. This suggests the presence of a deep Hercynian obstacle and also explains the presence of transverse (or radial) faults in the northern sector.
Nouvelles donnees sur le Jurassique superieur et le Cretace inferieur du Chenoua (Nord-Algerois)
Authors: Durand Delga Michel 
Published: June 2020

Abstract
Reports new data on upper Jurassic and lower Cretaceous formations of the Chenoua promontory in northern Algeria. The tectonic juxtaposition of Cretaceous formations originally deposited in widely separated basins and other structural and stratigraphic relationships are noted.
Sur les caracteres de la sedimentation des geosynclinaux mesozoiques [with discussion]
Authors: Colom Guillermo 
Published: June 2020

Abstract
The microfaunal associations of Jurassic and Cretaceous formations of the Betic cordillera and the Balearic islands, Spain, are planktonic. Of themselves, they have no bathymetric significance, but they occur consistently in deposits containing no detrital material, characterized by limy-marly facies, which is proof that the deposits were laid down in a broad geosyncline. It is therefore possible to recognize Mesozoic geosynclinal formations, in spite of contrary opinions.
Deux trouvailles de ceratites dans le "calcaire coquillier" lorrain
Authors: Maubeuge Pierre L. 
Published: June 2020

Abstract
Describes Progonoceratites saraviensis n.sp. from the basal zone of the Ceratites limestone of the Triassic limestone complex of Lorraine, France, and discusses its paleogeographic and paleoecologic significance. The cephalopod is considered to have been a member of an abundant population which inhabited a marine bottom and which perished catastrophically. The thanatocoenosis constitutes further proof of the rhythmic character of sedimentation of the Triassic limestones.
Etude structurale d'un micropli du synclinal de Saint-Disdier-en-Devoluy (Hautes-Alpes)
Authors: Albissin Micheline d' 
Published: June 2020

Abstract
A microfold has been observed in Tithonian (Jurassic) limestone of the northeastern margin of the Saint-Disdier-en-Devoluy syncline in the French Alps. In the plane perpendicular to its axis, the microfold is characterized by a series of stylolitic joints mainly oriented perpendicularly to the layers in two different planes. Detailed observations of these stylolites and fissures shows that there have been several phases of fissuring and stylolite formation between deposition of the limestone as a horizontal bed and the development of the microfold and that the direction of pressure changed during folding.
Nouvelles observations sur la couverture triasique et son substratum dans la region occidentale des Vosges; les forages de Vittel, Contrexeville et Lamarche; resultats de la campagne de recherche hydrogeologique 1954-1958
Authors: Minoux Georges 
Published: June 2020

Abstract
Describes details of the stratigraphy and ground- water zones of the Permo-Triassic sequence of the western Vosges region, France, on the basis of data from new borings (at Vittel, Contrexeville, and Lamarche) in the area northwest of the Faucilles mountains.
Sur la notion de "types" de gisements metalliferes
Authors: Routhier Pierre 
Published: June 2020

Abstract
Limitations of existing classifications of ore deposits are examined, and a new "natural" classificationis proposed, based on "types." The types are based on the mineralogic and geologic characteristics of the ore deposit itself and of the host rock. Among the characteristics to be determined for the ore deposit itself are its hypogene paragenesis, superficial alteration, and the chemical composition and ore content of both the hypogene and supergene ore. The characteristics to be determined for the host rock relate to the lithology and stratigraphy of the enclosing rocks and the presence of contact alteration, if any; the form of the ore body in relation to the structure of the country rock; the nearby presence of igneous rocks; and age, if determinable. Descriptions can be completed by giving a list of examples of similar deposits with their age, if known, and pertinent genetic hypotheses.
Contribution a l'etude des temoins d'actions pneumatolytiques d'age alpin; resultats d'observations dans les Alpes lepontiennes
Authors: Deicha Georges A. 
Published: June 2020

Abstract
Volatile constituents are found to occur abundantly in the liquid inclusions in quartz of an area south of the Gotthard massif, in the Lepontine Alps between the Greina and Simplon cols, where Mesozoic sediments have been subjected to strong Alpine metamorphism. Comparisons with neighboring regions suggest that processes of recrystallization can be attributed in large part to soaking by volatile-rich fluids. The petrogenetic and tectonic significance of the presence of fluids rich in CO &lt;sub&gt;2&lt;/sub&gt; is discussed.
Schema structural des Alpes maritimes franco-italiennes [with discussion]
Authors: Lanteaume Marcel 
Published: June 2020

Abstract
The structural pattern of the Franco-Italian Maritime Alps is outlined. Autochthonous units include the Argentera-Mercantour massif and a folded sedimentary zone which locally represents the dislocated cover of the massif. The Col de Tende unit is considered parautochthonous. Between the Tende col and the sea is a series of rootless overthrust units which rest either directly, or with an intermediate unit of Nummulitic (Tertiary) schists on the outer margin of the so-called imbricate Ligurian Pennine complex. The paleogeographic development of the region is sketched.
Decouverte d'une roche volcanique (andesite) dans la zone du Flysch des Aiguilles d'Arves
Authors: Barbier Reynold , Michel R. 
Published: June 2020

Abstract
Reports the discovery of a Tertiary andesite flow, probably submarine, at the base of Flysch formations near the Aiguilles d'Arves massif, France. This represents the second known occurrence of volcanic rock in place in the western Alps and clarifies the problem of the origin of the eruptive material in Flysch sandstones.
L'evolution volcano-tectonique du massif du Mont-Dore (Auvergne) pendant le Mio-Pliocene
Authors: Glangeaud Louis , Lemonnier J. C. 
Published: June 2020

Abstract
New surveys based on aerial photographs of the Mont-Dore massif (Auvergne, France) show the position of the network of dikes and their relation to faults, and thus throw light on the evolution of the Bourboule-Mont-Dore caldera and its magmas (trachyandesites). Volcanic-tectonic activity began in the Pontian and terminated in the lower Pliocene. Extrusion of lavas was simultaneous with caldera subsidence, which was contemporaneous with the tectonic processes responsible for orogenic activity in numerous areas borderingthe Alps.
