L'hydrogeologie d'une partie de la vallee de la Saoura et du Grand Erg occidental
Authors: Schoeller Henri
Published: June 2020

Although the geologic structure of both banks of the Saoura river, Algeria, is essentially the same, no ground-water aquifers occur on the right bank due to the absence of covering sands such as are present on the left bank where an extensive aquifer occurs in Pliocene limestones overlain by dunes and sands of the western Grand Erg. Formation of the aquifer is due to accumulation of rain waters which have percolated through the desert sands and not to infiltration of waters from intermittent streams descending the slopes of the Atlas mountains.

Contribution a l'etude des sediments argileux
Authors: Riviere Andre
Published: June 2020

The clay minerals produced during weathering of acid rocks by acid waters rich in humic materials generally belong to the kaolin group. Montmorillonites are usually formed by alteration of vitreous rocks. The weathering of most igneous and crystalline rocks, under normal pH conditions, usually results in the formation of minerals belonging to the illite-bravaisite group, which therefore are extremely abundant.

Introduction a l'etude thermodynamique de la petrogenese profonde
Authors: Glangeaud Louis
Published: June 2020

On the basis of the hypotheses that most of the factors involved in the formation of deep-seated rocks (such as velocity of atomic diffusion and reaction, viscosity, and thermal conductivity) are dependent on the degree of order-disorder in the solid or liquid material and that equilibrium disturbances in deep-seated rocks cause an increase or change of the energy component, the thermodynamic processes of deep-seated petrogenesis are discussed in the light of pressure (confining pressure and stress) and temperature variations taking into account the factors of time and space.

Authors: Le Maitre Dorothee
Published: June 2020

Describes Orthoceras coralliforme from Devonian deposits of north Africa (Saoura region, Algeria, and Tafilelt region, Morocco). Because the structure of internal molds resembles that of certain rugose corals, orthoceratids have frequently been erroneously assigned to Arthrophyllum. A satisfactory explanation for the structure has not yet been found.
Les phosphates du Sahara soudanais
Authors: Karpoff Roman , Visse L.
Published: June 2020

Two phosphate beds recently discovered in the Sudan region, French West Africa, represent beds formed in Paleocene or early Eocene time, which have subsequently been partly removed by erosion. They are rich in coprolites and bone debris. Because of a high content of aluminum, iron, and manganese the occurrences are not commercial deposits; the coprolitic elements may warrant exploitation, however.

Reflexions et discussions a la suite des recents travaux sur les feldspaths
Authors: Perrin Rene , Roubault M.
Published: June 2020

Recent investigations on albite and the albite-orthoclase system, particularly those of Bowen and Tuttle, are reviewed. The overall results indicate a low temperature of formation for plutonic rocks and pegmatites, a fact which is difficult to reconcile with the magmatist viewpoint. It is considered unlikely that granites could be so uniform in structure if formed in two such different manners as by crystallization from magma and by granitization. Since indubitable examples of granite formed by recrystallization in the solid state are recognized by all, it is concluded that all granites must be formed in that way.
Sur la geologie quaternaire des iles d'Hyeres
Authors: Bourcart Jacques
Published: June 2020

Observations geologiques dans la region d'Ouro Preto (Minas Gerais, Bresil)
Authors: Brajnikov Boris
Published: June 2020

Mountain ridges of Precambrian sandstone or quartzite in the Ouro Preto region of Brazil follow three principal directions. It is not yet clear whether these formations represent the lower Algonkian Minas series or the middle Algonkian Itacolomi series. The regional structure consists of a crystalline core overlain by phyllites and quartzites. The sedimentary cover has been sheared along with the core and, caught up in movements of isolated blocks of the core, subjected to more or less intense local displacement and folding. The result is a checkerboard of faulted segments. The topography is primarily determined by the structure, with erosion effects of secondary interest.

Lists of sponges from new localities in Ardeche, Savoie, and Poitou, and descriptions of two new species of hexactinellids are included. A table giving the distribution of species among the various localities shows that the Jurassic sponge fauna of France is very homogeneous.
Etude d'un nouveau gisement de plantes fossiles tertiaires et de quelques nouvelles especes decouvertes a Ceyssac
Authors: Grangeon Pierre
Published: June 2020

A description of the Crozas Tertiary flora, found in a cave in volcanic breccia in the valley of the Dolaizon, a small tributary of the Borne river, France. The cave is located about two kilometers from the Ceyssac fossil plant locality. Stratigraphic, paleobotanic, and paleontologic evidence all point to a pre-Villafranchian Tertiary age. The plants indicate a warmer, more humid climate than that of the present.
Sur une pegmatite a amazonite du Tibesti
Authors: Jeremine Elisabeth , Lelubre M. , Sandrea A.
Published: June 2020

An amazonite-bearing pegmatite mapped in the Dohona massif in the northeastern Tibesti mountains, French Equatorial Africa, is composed essentially of quartz with both amazonite and pink microcline, the latter perthitic, and accessory muscovite, topaz, and fluorite. To explain the presence of the two forms of microcline (which show identical composition upon spectral analysis), it is suggested that two phases are represented, one following closely upon the other. In the one, not all the equilibrium conditions for formation of pure microcline were present; the perthitic pink variety formed as a result of the tendency of soda (albite) and iron to exsolve. In the other, more stable phase the homogeneous amazonite crystallized. The sequence of the phases has not been determined.
Observations sur la bordure occidentale de la Bresse, region de Pont-de-Vaux (Ain)
Authors: Russo Philibert
Published: June 2020

Presents data on the distribution of the Pliocene and Quaternary in the western part of the Bresse region, France, obtained from 40 well borings, ranging from 7 to 17 meters in depth, in the vicinity of Pont-de-Vaux. Valleys cut in the Plaisancian (lower Pliocene) blue clays during later Pliocene times are filled with Quaternary deposits. The changes in level causing dissection and filling seem to have been produced by tectonic processes associated with the Alpine crustal movements, which caused subsidence in the west-central part of the region and uplift in the south, rather than by eustaticmovements.

Sur deux especes d'ammonites inedites de d'Orbigny et sur une espece nouvelle du tuffeau de Touraine
Authors: Sornay Jacques
Published: June 2020

Most of the 11 upper Cretaceous ammonites in the d'Orbigny collection, for which no descriptions were published, correspond to forms since described by others, but two seem to represent new forms which should be preserved: Ammonites combesi and A. canthus, belonging to the genera Mammites and Prionotropis, respectively. A related species, P. turoniensis n. sp. from the Touraine region, France, is described from a specimen in the Peron collection.
Structure et evolution de la zone sub-bibanique dans la region de Mansourah-les-Biban (departement de Constantine)
Authors: Caire Andre
Published: June 2020

Discusses and illustrates schematically the evolution of the complex structure of the sub-Bibanic zone in the Mansourah-les-Biban region, which lies between the Biban and Mansourah ranges in Constantine department, Algeria. Older layers have been overturned and thrust southward in successive stages on top of Miocene beds, the whole being further complicated by warping.
Interpretation tectono-physique des caracteres structuraux et paleogeographiques de la Mediterranee occidentale
Authors: Glangeaud Louis
Published: June 2020

The structural evolution of the western Mediterranean region cannot be explained on the basis of any single category of physical processes, such as continental migration or subcrustal convection currents, but by action of several processes, whose individual roles varied with time and place. Four stages are distinguished in the structural evolution--disjunction leading to separation of the "Mediterranean mosaic" into several fragments at the close of the Paleozoic and the beginning of the Mesozoic; monoliminary (autonomous) evolution of the border of certain of these fragments during the Mesozoic; diastrophic activity in middle Eocene to upper Oligocene time, during which the blocks of the mosaic were squeezed between Europe and Africa; Miocene to Plio-Quaternary phases of relaxation, accompanied by isostatic readjustment and subcrustal flow.

Deux applications de criteres geometriques a la determination du mode de genese de filons de pegmatite [with discussion]
Authors: Perrin Rene , Roubault M.
Published: June 2020

Gives two examples, from Finistere (France), of the application of geometric criteria to determination of the origin of pegmatite veins. Both are cases where well-developed networks with parallel borders are nevertheless interpreted as being of replacement origin. Critical comments by various colleagues and authors' rebuttal are appended.
Etude petrographique et mineralogique des sediments meubles de la region de Salles (Gironde)
Authors: Seronie-Vivien Roger
Published: June 2020

A petrographic and mineralogic study of the detrital formations of the Salles region in the Aquitaine basin, France, which include Miocene (Helvetian), Pliocene, and lower and upper Quaternary beds. The sandy formations of each stage are very homogeneous, from the granulometric as well as the mineralogic point of view. Four phases of sedimentation are indicated by statistical study of the heavy minerals; thus the stratigraphy can be defined solely by means of petrographic criteria.
Quelques observations petrographiques sur le NW du massif de Levezou (Aveyron)
Authors: Collomb Pierre
Published: June 2020

The metamorphic series of the northwestern Levezou massif, Aveyron, France, is characterized principally by enrichment in silica and potash. This enrichment (possibly due to concentration of femic elements in small lenses in the migmatites) is not uniform, but is always present, both in the mica schists and paragneisses, which grade into migmatites, and in the greenstones bordering the migmatite massif.

Le contact Jura-Bresse dans la region de Lons-le-Saunier
Authors: Michel Pierre , Appert George , Bonte Antoine , Lavigne Jacques , Lefarrais Andree , Lienhardt Georges , Ricour Jean
Published: June 2020

New information from borings shows that in the region to the west and north of the Lons-le-Saunier basin, France, the Jura border is thrust over the Tertiary of the Bresse region. The age of the movement is post-Pontian, and the amplitude over five kilometers at certain points. The movement occurred along gypsum and salt zones in the lower Keuper and Muschelkalk (Triassic) without disturbing the underlying Triassic, Permian, and Carboniferous beds.

Authors: Stchepinsky Vladimir
Published: June 2020

Outlines the middle and upper Jurassic history of the Morvan-Vosges strait in the region between Neufchateau (Vosges) and Chatillon-sur-Seine (Cote-d'Or), France, as deduced from vertical and horizontal variations in facies. Tectonic activity in the Vosges and Morvan massifs does not seem to have been simultaneous.
Les formations littorales anciennes du Ri pres de Douarnenez (Finistere) [with discussion]
Authors: Giot P. R. , Guilcher Andre
Published: June 2020

A study of a littoral formation, a marine sand cemented by limonite, which occurs in the Ri beach region, near Douarnenez, Finistere, France. The ferritization and consolidation seem to have been caused by the action of local springs and influenced by the position of the formation along the shore. The age is probably Normanian (early Quaternary).

The Entzheim boring, south of Strasbourg in Alsace, France, has provided a complete section through upper Oligocene beds. A meter-by-meter study of the microfauna reveals details on the decreasing salinity of the sea in which these strata were laid down.
Les terrasses quaternaires de la vallee de l'Huveaune (Bouches-du-Rhone)
Authors: Bonifay Eugene
Published: June 2020

Describes the three principal sets of terraces developed in the Huveaune valley, near Marseilles, France, the youngest of which corresponds to the Wuerm (Pleistocene) stage. These terraces were developed during the course of a torrential regime and thus were extremely sensitive to slight climatic variations. They therefore reflect the general paleoclimatologic conditions which obtained in lower Provence at the end of the Quaternary.

Authors: Laporte Jean
Published: June 2020

The metamorphic rocks outcropping around Ersa and Centuri in the northwestern part of Corse cape on Corsica, France, may possibly be the more highly metamorphosed equivalents (including retrograde products) of the other rocks forming the cape.
Flore et stratigraphie du terrain houiller de la region de Lons-le-Saunier (Jura)
Authors: Greber Charles
Published: June 2020

Lists the most characteristic Stephanian plants found in borings in the Carboniferous coal-bearing formations of the Lons-le-Saunier region, France. In some boreholes lower and middle Stephanian floras could be distinguished. The transition between them is gradual because sedimentation was continuous, and no definite boundary could be established. The middle Stephanian is more extensive, as in the coal basins of the Central Massif. Transgression in the region seems to have been toward the north.

Authors: Saint-Seine Roseline de
Published: June 2020

An account of acrothoracic cirripeds from several zones in Liassic, Jurassic, Cretaceous, and Miocene localities of France. It is tentatively concluded that a considerable variation in abundance has taken place. During the Liassic, late Cretaceous, and Miocene, conditions were more favorable for their existence than at present. A description of Zapfella pattei n.g. n.sp. is included.
Colorimetrie de sediments quaternaires et paleoclimats; premiers resultats [with discussion]
Authors: Alimen Henriette
Published: June 2020

Paleoclimatic conclusions are drawn from color variations in Quaternary sediments and fossil soils in the central French Pyrenees. They agree with results of similar observations in different parts of France. During glacial and interglacial fluctuations, the Quaternary climate of France became increasingly cold and reached a maximum in the Wuerm.
