Remarques sur la structure du pays basque
Authors: Lamare Pierre 
Published: March 2020

Abstract
Remarks on the structure of the Basque country, Lower Navarre, France. Refutes three structural interpretations of Leon Bertrand--(1) the existence of a Labourd nappe, (2) reverse overthrusts in the Ispeguy col, and (3) overthrusts or reverse thrusts on the borders of the Saint-Jean-Pied-de-Port Triassic basin--and concludes that the Pyrenean orogeny was much less intense in the Basque region than in neighboring regions.

Le sous-sol de la plaine alluviale du Veron (Indre-et-Loire)
Authors: Lecointre G. , Douville F. 
Published: March 2020

Abstract
The Veron alluvial plain, located above the confluence of the Loire and Vienne rivers, France, is underlain by a series of Cenomanian (Cretaceous) deposits which are not horizontal, but constitute a dome which was subjected to considerable weathering. In the Chouze area, in the central part of the dome, Jurassic limestones occur below the plain. Their fauna (which is described) is composed mainly of numerous pelecypods and ammonites (including one new species).

Notes stratigraphiques et paleontologiques sur la region du Dj. Ouenza (Algerie) (Aptien, Albien, Cenomanien)
Authors: Dubourdieu Georges , Sigal J. 
Published: March 2020

Abstract
Describes the stratigraphic subdivisions and fauna of the Aptian to Cenomanian (Cretaceous) formations of the Ouenza mountain region, Algeria. Correlation of the vertical distribution of foraminifers with successive ammonite zones permitted identification of certain of the foraminifers as index microfossils. Descriptions of the Cenomanian ammonite Flickia rudelli n.sp. and two new species of foraminifers, Epistomina colomi and E. scala, are included.
Notes sur la structure geologique des environs de Texenna (Petite Kabylie, Algerie)
Authors: Durand-Delga Michel 
Published: March 2020

Abstract
North of Texenna, Algeria, Albian-Aptian (Cretaceous) Flysch deposits transgressively overlie Paleozoic crystalline basement rocks of the Little Kabylia massif. South of Texenna crystalline basement rocks are thrust over the Flysch. Dislocation took place prior to deposition of Numidian deposits (probably Oligocene).
La terminaison de l'axe de Vigny et la tectonique du meandre d'Acheres
Authors: Bourcart Jacques , Soyer Robert 
Published: March 2020

Abstract
Study of the stratigraphic and tectonic relations of strata underlying modern alluvial deposits and overlying the Cretaceous of the Acheres meander region in the Seine river valley, France, revealed by a series of borings, shows that the Vigny structural axis terminates at the Seine and that the Acheres meander is located in a synclinal trough.
Relations entre la tectonique et la morphologie de la plaine du Rhin, en Alsace et au grand duche de Bade
Authors: Schlumberger R. A. 
Published: March 2020

Abstract
The morphologic features of the Rhine river plain in Alsace (France) and Baden (Germany), observed during airplane reconnaissance, corroborate and supplement data obtained by geologic investigations, borings, and geophysical prospecting relating to the structure of the Rhine trough and associated surface forms. It is concluded that, below the alluvial deposits of the plain, the terrain is highly folded and faulted and that crustal movements, which produced a regional structure resembling a piano keyboard, continued to the present time.
Sur l'existence et la nature de l'apport chimique dans certaines series cristallophylliennes
Authors: Lapadu-Hargues Pierre 
Published: March 2020

Abstract
Distinguishes seven groups of metamorphic rocks according to chemical composition, ranging from argillaceous schists to granites and granulites, and discusses the physicochemical factors involved in the transformation of the pre-existing rocks during metamorphism, with special reference to the addition of calc-alkaline material from deep-seated magmas, the behavior of component elements, and the migration of ions during alteration.
Les bassins carboniferes du Sud-Oranais (Algerie); le bassin de Colomb-Bechar-Kenadza et le bassin du Guir
Authors: Deleau Paul 
Published: March 2020

Abstract
The Westphalian (middle Carboniferous) strata of the Colomb-Bechar-Kenadza and Guir basins in southern Oran, Algeria, are lagoon deposits formed in continental or marginal paralic basins in which there were frequent marine invasions from the north until middle Westphalian time. The strata were not subjected to Hercynian (Paleozoic) crustal movements until after the lower Stephanian (upper Carboniferous), at which time extensive anticlines were formed, some of which were further dislocated during Tertiary tectonic activity.
Methode simplifiee de diagnose roentgenographique des argiles; application a l'etude des bravaisites (illites); leur evolution geologique
Authors: Riviere Andre 
Published: March 2020

Abstract
Reports the results of x-ray analyses of oriented samples of clays, on the basis of which phyllitic minerals belonging to the kaolinite, montmorillonite, and bravaisite groups could be distinguished from each other and from fibrous clay minerals. Application of x-ray methods to a study of bravaisite (which has priority over illite) shows that bravaisite exhibits a tendency to develop toward a more stable structure (montmorillonite and particularly kaolinite).
Sur la presence de solenopores dans le Bajocien inferieur (Ledonien) du plateau de Langres
Authors: Gardet G. , Mercier J. 
Published: March 2020

Abstract
Solenopores associated with corals were recently discovered in lower Bajocian (Jurassic) strata of the Langres plateau, France. The faunal association is generally typical of younger Jurassic formations and has not previously been found in basal Dogger beds. The algae are assigned to a new variety, lingonensis, of Solenopora jurassica.
La faille de l'Arve au viaduc Sainte-Marie (Les Houches, Haute-Savoie)
Authors: Deicha Georges A. 
Published: March 2020

Abstract
A polished surface covering some 30 square meters of Carboniferous rock exposed in the vicinity of the Sainte-Marie viaduct in the Aiguilles Rouges massif, Haute-Savoie, France, represents a plane of the Arve fault along which renewed movement had taken place. The absence of mineralization along the fault indicates that the recurrent movement was post-Alpine.
La structure du nord-ouest de l'Argentine avec quelques reflexions sur la structure des Andes
Authors: Picard Leo 
Published: March 2020

Abstract
With the exception of a brief period of folding in the upper Tertiary, no tangential orogenic movements have taken place in the Andes of northwest Argentina since the beginning of the Carboniferous. Formation of the ranges of the Andes was due to vertical crustal movements, particularly Plio-Pleistocene epeirogenic uplift.
Contribution a l'etude des schistes, calcschistes et grauwackes d'Angers; III, La faune des schistes bleus des fours a chaux d'Angers
Authors: Pillet Jean 
Published: March 2020

Abstract
The Devonian formations in the eastern end of the Saint-Julien-de-Vouvantes basin in the Angers region, France, consist of a continuous series of lower Siegenian to Emsian beds. The fauna (trilobites and brachiopods) recently discovered in blue shales within the sequence confirms the presence of the middle Siegenian zone.

Nouvelles observations sur les sables alveolaires
Authors: Baudoin Rene 
Published: March 2020

Abstract
The behavior of alveolar sands under foot affords information on their structure. A "sand drawer" designed for taking undisturbed samples, here described in detail, is an aid in making observations of this behavior. The sands are divided into two categories: firm sands, either solid under foot (compact sands) or elastic (containing bubbles below a firm crust 10 cm or more in thickness); and yielding sands, either thixotropic (yielding only when saturated) or lacking in resistance, both wet and dry. Structural characteristics of recent and fossil alveolar sands are discussed, with data on localities where each type may be found. The evolution of alveolar sands is influenced by the presence of the animals inhabiting them. In fossil form they are evidence of the high-tide limit of former seas.
Sur la presence d'inocerames dans un niveau postmaestrichtien pres d'Ain-Fakroun (Algerie)
Authors: Drooger C. W. , Voute C. 
Published: March 2020

Abstract
Study of microfaunas associated with pelecypods belonging to the genus Inoceramus found in Cretaceous deposits near Aien-Fakroun (Algeria) shows that the latter sometimes lived on in Algeria beyond the Maestrichtian. Since similar occurrences have been noted in other localities in north Africa and in Anatolia (Turkey), Inoceramus cannot be used in these regions to define the upper limit of the Maestrichtian. Exact relations between the north African and Anatolian forms have not been worked out, but in all cases they seem to be representatives of the I. regularis group.
Contribution a la stratigraphie du Keuper du Jura
Authors: Bonte Antoine 
Published: March 2020

Abstract
Defines the stratigraphic subdivisions of the Keuper (Triassic) series of the Jura region, France, on the basis of a study of numerous borings and extremely detailed mapping. Special attention is called to a dolomite, averaging 10 m thick, which is an important key zone in the upper Keuper, and to other diagnostic features.
L'orogenese de l'Atlas tunisien
Authors: Castany Gilbert 
Published: March 2020

Abstract
The Atlas mountains of Tunisia have undergone a long and slow evolution. East-west trending structures were developed during Mesozoic deformation. Tertiary (pre-Burdigalian) movements heralded the major Plio-Pleistocene diastrophism, which continued until the end of the Pleistocene and produced folds with northeast-southwest trending axes. In recent Quaternary times, isostatic readjustment has produced depressions, both parallel and at right angles, which are superposed on the old fractures of the basement complex.
Observations sur la structure microscopique de quelques houilles limniques
Authors: Bergounioux Frederic Marie , Doubinger Jeanne 
Published: March 2020

Abstract
Microscopic study of the limnic coals of the Decazeville basin, France, reveals differences between these and paralic coals, which result from the difference in size of their respective depositional basins. Classification of the elements of the limnic coals according to decreasing density is impossible; because of the small dimensions of the lacustrine depositional basins the most diverse elements are found mixed in the limnic coals, giving them a characteristic aspect.
Les galets des cordons littoraux actuels en Norvege meridionale
Authors: Berthois Leopold , Berthois Catherine 
Published: March 2020

Abstract
The gravels of present-day boulder trains of the coasts of southern Norway have been studied and compared with material from the coast of Brittany (France). The former have been derived from Quaternary deposits whose components were subjected to a long previous history, whereas the latter was recently derived from rock. The differences are reflected in the coefficients of dissymmetry and flattening. Moreover, different hydrodynamic conditions influence deposition in the two regions.
Les liogryphees jurassiques de l'est du bassin parisien; II, Liogryphees du Bajocien
Authors: Charles Robert P. , Maubeuge P. L. 
Published: March 2020

Abstract
Describes three species of Liogryphaea from the eastern Paris basin, L. oblonga n.sp., L. lampada, and L. ampla n.sp. All three are limited to the Bajocian, and evolved from L. phaedra.
Decouverte d'un rostre chez Stenodictya lobata Brgt. (paleodictyoptere stenodictyide) et le probleme des protohemipteres
Authors: Laurentiaux Daniel 
Published: March 2020

Abstract
Describes a rostrum in the paleodictyopteran Stenodictya lobata from Carboniferous deposits of the Commentry region, Allier, France, which is structurally similar to that in Eugereon boeckingi. Comparison of the wing venation of Eugereon and Dictyoptilus suggests that the former should be assigned to the Dictyoptiloidea, which were derived from the Stenodictyidae.
Contribution a l'etude vulcanologique et morphologique de l'Islande sud-ouest
Authors: Bout Pierre 
Published: March 2020

Abstract
Volcanologic and geomorphic studies in southwestern Iceland show that (1) the basalt breccias of the palagonite deposits exhibit striking analogies with those of Velay (Haute-Loire, France), and similarly seem to be of directly eruptive origin; (2) the fissured domes of certain basalts are the effect of dilatation during cooling; (3) the topography is controlled not only by volcanism but also by four systems of fractures; (4) present eolian action is due to winds from the north and northeast (glaciers) or south and southeast (Atlantic Ocean); (5) dreikanter basalt blocks are now being formed only on the south coast, those in the interior having been formed earlier in times of more extensive glaciation; (6) polygonal soils were formed by shrinkagefollowing pressures developed by winter ice, the size of the polygons depending on whether segmentation was easy (small polygons) or difficult (large polygons).
Mastodonte de Bourg-Saint-Bernard et erosions miocenes dans le bassin sous-pyreneen
Authors: Astre Gaston 
Published: March 2020

Abstract
The discovery of a mastodon molar at Bourg-Saint-Bernard supports the conclusion that the Stampian deposits of the region were eroded during the Miocene, and therefore that the Miocene in the French Pyrenean basin was deposited unconformably (and sporadically) on the Stampian, in contrast to the normal depositional sequence of the Miocene of Gascony.
Sur la presence d'amas gabbro-dioritiques en bordure des migmatites du versant SW du Canigou (Pyrenees orientales)
Authors: Guitard Gerard 
Published: March 2020

Abstract
Describes gabbro-diorite masses on the southwest slope of the Canigou in the eastern French Pyrenees. Such basic masses are common in the transition zone of the migmatites in this region; they are older than the late miggmatitic granites in the transition zone and are always associated with marble. They are considered contemporaneous with the principal phase of migmatization (brecciation), and are the result of replacement at contacts with the marble. Chemical analyses are included.
Note sur le gisement uranifere de Saegmuehlen, pres Sulzburg (Foret Noire); sa place parmi les gites uraniferes europeens
Authors: Geffroy Jacques , Lenoble Andre 
Published: March 2020

Abstract
Describes a uraniferous locality in an old cobalt mine at Saegmuehlen, near Sulzburg in the Black Forest, Germany. The mineralization, which seems to be related to the granitic massif south of the Black Forest, is in the form of thin veinlets of pitchblende accompanied by loellingite and sulfides of Pb, Cu, Zn, Fe, and Sb in a quartz-carbonate gangue. Among European uraniferous deposits, there appears to be a progressive gradation from the Central Massif type, intragranitic and dominantly epithermal, to the central European type, located at the periphery of granite batholiths and dominantly mesothermal. Both types are related to Hercynian (Paleozoic) mineralization; the former seems to represent a late-stage product, derived from solutions originating deep in batholiths, whereas the latter was derived from more superficial zones.
Microfaunes pelagiques (calpionelles, fissurines) dans le NE de la Berberie
Authors: Colom Guillermo , Castany Gilbert , Durand Delga Michel 
Published: March 2020

Abstract
Describes the principal occurrences of pelagic microfaunas in the northeastern Barbary region--in the Numidian range of northern Constantine, Algeria, and in the eastern Atlas range in southern Tunisia. Study of their geographic and stratigraphic distribution indicates that pelagic Alpine microfaunas freely invaded the region south of the now uplifted Paleozoic massif of the Kabylia region during the latest Jurassic and earliest Cretaceous.

On the basis of paleontologic and sedimentologic data, the boundary between Aptian and Albian (Cretaceous) formations of the Saint-Dizier region, France, is placed between the Gargasian white sand and the Albian green sand.
Sur des empreintes vegetales du Continental intercalaire de Dibella (territoire du Niger)
Authors: Boureau Edouard 
Published: March 2020

Abstract
Describes four new species--Podocarpites? saharianum, Laurophyllum gadilhei, Cinnamomoides faurei, and C. tchadense--from Cretaceous beds in the Continental intercalaire formation near Dibella, French West Africa. This angiosperm flora is of a quite different type than other floras known from the continental sequence of the Sahara.
Gites de cuivre de type pneumatolytique et pegmatitique dans les orthoamphibolites du sud de Madagascar
Authors: Kovenko Vladimir 
Published: March 2020

Abstract
The copper deposits of southern Madagascar are of pegmatitic or, more frequently, pneumatolytic origin. The Besatrana (quartz vein), Andokaolo and Vohitany (pegmatite), and Besakoa (pneumatolytic) deposits are described. The last is the largest, with pyrite, sphalerite, and traces of molybdenum and lead associated with chalcopyrite. All occur in orthoamphibolites interfingering or cutting rocks of the Precambrian Vohibory series. The copper deposits of the Karroo system are probably secondary concentrations.
Contribution a l'etude des spongiaires permiens du Djebel Tebaga (extreme sud tunisien)
Authors: Termier Henri , Termier G. 
Published: March 2020

Abstract
As part of a revision of Permian faunas of the Tebaga massif in southernmost Tunisia, the principal sponges are described. Calcispongia, Demospongia, and Hyalospongia thrived in a very special environment. The species are related to faunas of Sicily, the United States, and the Far East. Many genera represented in the Tebaga fauna have not yet been recorded from beds older than Triassic or even Liassic. Two new genera are created, Polyedra and Tebagaspongia.
Caractere de la deformation alpine dans les schistes cristallins du massif du Mont-Blanc
Authors: Belliere Jacques 
Published: March 2020

Abstract
Field observations and microscope analyses of crystalline rocks of the Mont Blanc massif (France) lend support to the concept that Alpine deformation was continuous in space and regional in scale. The Mont Blanc and Aiguilles Rouges massifs are both part of the same Prealpine basement, which became separated by Alpine deformation. The general structural trend of the Aiguilles Rouges massif is north-south, but that of the Mont Blanc massif more closely corresponds to the Alpine trend. This change in orientation is directly related to mylonization of schistose crystalline basement rocks, under Alpine stresses.
L'ile Bach Long Vi (golfe du Tonkin)
Authors: Saurin Edmond 
Published: March 2020

Abstract
The island of Bach Long Vi in the middle of the Gulf of Tonkin (South China sea) is underlain by late Tertiary continental sandstones, containing lenses of lignitic material, which indicate that submergence of the gulf was relatively recent. The island is bordered by Quaternary marine terraces (at elevations of 2, 4, and 10 meters) and beveled on top, at 55 meters, by a remnant of a more extensive peneplain.

Abstract
Summarizes the stratigraphy of middle Jurassic sections exposed in the Creuse, Gartempe, and Vienne valleys, Poitou region, France, with special reference to the position of Bathonian brackish zones, and describes eleven species of ostracods from beds representing lacustrine to mesohaline environments. The ostracods resemble those of the upper Malm and exhibit advanced evolutionary features. Several new species are represented in the fauna.
Sur la constitution geologique du K2 (8 611 m) dans la chaine du Karakoroum (Himalaya)
Authors: Desio Ardito , Zanettin B. 
Published: March 2020

Abstract
K2 (Mount Godwin Austen) in the Karakoram range, north Kashmir, is composed essentially of a metamorphic series (mainly the "K2 gneiss"), consisting of sediments that were subjected first to regional metamorphism and later to feldspathization as a result of intrusion of the neighboring Baltoro-Panmah granite batholith. The structure is dominantly that of an anticline trending south-southwest-north-northeast and cut by a principal fault passing close to the summit. Two other faults appear to be "grafted" on the main fault.
