The data to be obtained in this study will be analyzed quantitatively descriptive and strengthened by interviews from the community, then the data obtained will be classified by the percentage technique.
Mise en place de la circulation au Pacifique central equatorial et des assemblages des nannofossiles calcaires au Neogene (Leg DSDP 85); II, Influence de l'emersion de l'isthme de Panama, entre 7 et 2 Ma
Authors: Pujos Annick
Published: March 2020

Four sites were drilled during DSDP Leg 85 in the equatorial Pacific. Calcareous nannofossils from Mio-Pliocene sediments recovered from the central and eastern parts of the high-productivity area were studied in detail. Two main geologic events occurred during the Neogene which modified the water masses circulation in the Pacific Ocean: (1) between 15 and 7 Ma, Antarctic glaciation influenced greatly the Pacific circulation (first part of the study); (2) between 7 and 2 Ma, the progressive uplift of the isthmus of Panama gave rise to a tropical and an equatorial upwelling, which changed the distribution of discoasters and Coccolithus pelagicus, and triggered off the recent Pacific circulation.

Quelques observations sur le bassin fluvio-lacustre eocene du Minervois
Authors: Barrabe Louis
Published: March 2020

During the middle and upper Eocene relatively high land masses were present in the southern part of the Minervois basin, Languedoc, France, with numerous streams which contributed to deposition of fluvial deposits northward. In the northern part of the basin, on the south border of the Montagne Noire, the relief was more subdued, with extensive lakes. The great thicknesses of lacustrine deposits are attributed to subsidence of the basin.

Analyse stratigraphique et structurale du cristallophyllien
Authors: Demay Andre
Published: March 2020

Outlines criteria for interpreting the stratigraphy and structure of regionally metamorphosed terrain, citing examples from various crystalline complexes of France. Parametamorphic rocks exhibit a regular sequence, whereas injection gneisses and migmatites do not, because of the irregularity of the magmatic activity involved in their formation. Granites of deep-seated origin are always accompanied by migmatites, but never by a microgranitic aureole. Interpretation of the effects of orogenic activity or deformation is based on analysis of axial orientations, the grade of metamorphism, and microstructures.

Roches eruptives du bassin de Laval (Mayenne) et des environs de Sable (Sarthe)
Authors: Raguin Eugene , Zvereff R.
Published: March 2020

Although conclusive evidence is lacking, due to the advanced state of alteration of the rocks, the spatial relations of microgranite in Ordovician deposits and rhyolites in Culm (Carboniferous) formations of the Laval basin, France, indicate that intrusion of the one and extrusion of the other were genetically related processes. Basic rocks, considerably altered, interstratified in Culm deposits in the vicinity of Sable are considered lava flows which were emplaced during sedimentation of the Culm beds.

Les conglomerats du Verrucano dans la region de Briancon (Hautes-Alpes) et leurs rapports avec le Carbonifere
Authors: Feys Robert , Greber Ch
Published: March 2020

Concludes that the contact between the Verrucano conglomerate of the Briancon region, France, and underlying Carboniferous deposits is stratigraphic rather than tectonic, on the basis of included reworked Carboniferous pebbles, the superposition of the conglomerate on Carboniferous strata of different ages, the absence of Stephanian beds, the persistence of the detrital facies of the conglomerate, and the existence of an angular unconformity at several localities. Generally assigned to the Permian, the conglomerate exhibits many characteristics similar to those of the basal conglomerate of Triassic quartzites.

Etude de quelques polypiers bajociens du Jura meridional
Authors: Pelletier Marcel
Published: March 2020

A study of the coral faunas of two limestone zones intercalated in the Bajocian (Jurassic) of the southern Jura region, France, one in the Sonninia sowerbyi zone (lower Bajocian) and the other at the top of the Otoites sauzei and in the Witchellia romani zones (middle Bajocian). New species described are Isastrea alloiteaui, Latomeandra thorali, and Periseris pressiatensis. Since no species is found in both lower and middle Bajocian, the stratigraphy can be based on corals, where ammonites are lacking.

Remarques au sujet de la distribution de la schistosite dans les Pyrenees; note preliminaire
Authors: Fourmarier Paul
Published: March 2020

The rocks of the Pyrenees show various types of small-scale deformation such as foliation, microfolding, and schistosity. Static load has played a major role in the development of schistosity; where the load was greater, schistosity is developed into higher stratigraphic zones. In general, the schistosity is symmetrically disposed with respect to the axis of the range, following the general trend of the folding.

Note preliminaire sur un plissement rencontre entre Pirapora (Minas Gerais) et Formosa (Goiaz), Bresil
Authors: Ruellan Francis
Published: March 2020

Extensive folding, rather than a predominance of horizontal Cretaceous strata as heretofore mapped between Pirapora (Minas Gerais) and Formosa (Goiaz), southwest of the Sao Francisco river basin, Brazil, is revealed by the drainage pattern, aerial photographs, and field observations. The formations involved are analogous to those of the Sao Francisco-Bambui and Gerais series, and thus are probably Ordovician and Silurian. They have been folded, presumably in the Taconian or Caledonian orogeny, peneplaned, armored with a protective lateritic crust, uplifted, and intensely dissected, with the result that an Appalachian type of topography was developed.

Les calcaires stratifies a Daviesiella llangollensis de la bande d'Avesnes
Authors: Derville Henry
Published: March 2020

Presents stratigraphic details and (in the second note) describes calcispheres of the Daviesiella llangollensis-bearing limestones of the Avesnes limestone band (Carboniferous), as exposed in the Baldaquin quarry, Avesnes region, France. These stratified limestones overlie massive Productus sublaevis-bearing limestone, are gray or blue, fine-grained, and are characterized by a relatively compact zoned or concretionary texture. The zoning and concretions are clearly of organic (algal) origin. Dolomitization has obliterated the texture at several horizons, but an occasional visible nodule suggests that these layers are also, at least in part, of organic origin.
Les galets perces du Marquesado del Cenete (province de Grenade, Espagne)
Authors: Ceccatty R. de , Roziere G.

The artificial-looking regular conical perforations in many of the slaty pebbles found on the Marquesado del Cenete plain in Granada, Spain, are attributed to the particular nature (foliated) of the rock and local climatic conditions.
Remarques sur les caracteres et l'evolution de la paleogeographie de la zone brianconnaise au Secondaire et au Tertiaire
Authors: Lemoine Marcel
Published: March 2020

Discusses the stratigraphy and paleogeography of the Brianconnais zone in the vicinity of Briancon, France, particularly during the geanticlinal period (upper Triassic to lower Eocene). The geanticline was formed by a pre-Bathonian "pulsation" rather than by marked orogeny; its relief was always very low, and erosion and sedimentation were consequently weak. There were areas, not only at the western margin, but even in the axial and eastern portions of the Brianconnais zone, where sedimentation was continuous from the Callovian (Jurassic) to the upper Cretaceous or later; the stratigraphic breaks usually considered characteristic of the Brianconnais facies are lacking.
Etude petrologique de l'episyenite d'Eup (Haute-Garonne)
Authors: Ravier Jean , Thiebaut Jean
Published: March 2020

The episyenite northeast of Eup, Haute-Garonne, France, intruding the Triassic sedimentary cover on the eastern margin of the Barousse massif, is essentially composed of albite, barkevicite, and epidote, and is considered to have evolved from a berondrite. It is traversed by leucocratic veins, consisting almost exclusively of more or less dipyrized plagioclase, which represent an end stage in which the amphibole has disappeared. Chemical analyses are included.
Existence d'un desert froid au Quaternaire ancien dans la region littorale vendeenne
Authors: Ters Mireille
Published: March 2020

The early Quaternary history of the coastal region of Vendee, France, is reconstructed from study of eolian sands veneering the upper sides of valleys. At the time of the first glacial stage, the region was covered by thick desert sands. That this cold desert was not entirely devoid of vegetation is indicated by fossil soils in the quarries at Pin and Roussiere. Subsequently, most of the eolian material has been reworked into terraces by streams and by the sea.
Stratigraphie de l'Antecambrien au Sahara [with discussion]
Authors: Lelubre Maurice
Published: March 2020

The various Precambrian areas of the Sahara region are very similar geologically. Within the basement complex, the Pharusian unconformity separates two great groups of crystalline rocks. The older group, generally katamorphic, corresponds to the Suggarian cycle; the younger, generally epimorphic, corresponds to the Pharusian cycle. In the latter, several distinct phases can be distinguished which have not as yet been correlated between the different areas. Throughout the region the Precambrian is separated from younger beds by the Tassilian unconformity.

Schistes cristallins et granites en Bretagne meridionale; a propos des "haelleflints"
Authors: Cogne Jean
Published: March 2020

The rocks originally mapped as haelleflints (more or less crushed tuffaceous rhyolite) in southern Brittany, France, are actually mylonites composed of predominantly granitic material. Their presence in the long strip of syntectonic Hercynian granulites traversing the north flank of the Cornouaille anticline indicates that dislocation of greater magnitude than heretofore realized took place.

Essai de paleogeographie de l'Ile-de-France au Sannoisien
Authors: Girard d'Albissin Micheline
Published: March 2020

A detailed stratigraphic study of the Sannoisian (Tertiary) of the Ile-de-France in the Paris basin (France) shows that pronounced relief, shallow waters, and a variable rate of subsidence easily explain the close association of continental, lacustrine, marine, and lagoonal facies in the sequence. The lagoonal regime was predominant in the lower Sannoisian, the lacustrine in the upper; local and temporary marine invasions occurred throughout the whole time interval.
Magnesites (giobertites) des Pyrenees occidentales
Authors: Destombes Jean Paul
Published: March 2020

The magnesite deposits recently discovered in the western Pyrenees exhibit striking similarities to Austrian occurrences. The MgO, probably derived from greenstones, was incorporated in hydrothermal solutions which migrated along deep east- to east-northeast-trending fractures in the Ordovician basement and enriched limestones but not dolomites. Mineralization took place after the middle Triassic, probably before Liassic time, and was related to a post-tectonic phase of the Hercynian orogeny rather than to granite emplacement.

Describes several rock masses rising above the Quaternary plain of the Chad region (French Equatorial Africa) in the vicinity of Fort-Lamy. East of Fort-Lamy, most of them consist of a cupola of normal granite capped by a columnar zone whose interstices are characterized by rhyolitic facies, above which isolated round masses of granite in rhyolite or, in some cases, pure rhyolite occur, the transition frequently taking place within 20 meters. Northwest of Fort-Lamy, the structures are similar but the rock is almost entirely rhyolitic; one of them certainly is the upper part of a volcano.
Les lentilles aquiferes dans le SW de la Dombes et la colline de la Croix-Rousse a Lyon
Authors: Russo Philibert
Published: March 2020

Ground-water aquifers in the southwestern part of the Dombes plateau, France, consist of lenses in Tortonian or Pontian deposits of the Molasse (Tertiary) sequences where they occur between the impermeable crystalline basement and an overlying impermeable layer of Pleistocene glacial clays. The aquifers are dome-shaped masses whose orientation differs, in part, from the general southeast dip of the basement. Ground waters of the Croix-Rousse hill, at Lyons, seem to be of purely local origin.

Borings in the Lons-le-Saunier region, France, show that thrusting of the western border of the Jura massif over the Bresse Tertiary formations took place over a surface which was eroded in the Tertiary and partially covered by conglomerates.
Les trilobites des calcaires a polypiers siliceux (Eifelien) du synclinal de Villefranche-de-Conflent (Pyrenees-Orientales)
Authors: Cavet Pierre , Pillet J.
Published: March 2020

Describes a trilobite fauna (eight species) from the siliceous coral-bearing limestone formation of the Villefranche-de-Conflent basin in the French Pyrenees. The fauna confirms an Eifelian (Devonian) age for the formation. A new subgenus, Longiproetus, is proposed.
Sur un mode tectonique particulier des formations ordoviciennes de la mine de Bentaillou (Ariege)
Authors: Destombes Jean Paul
Published: March 2020

North-south sections across the eastern end of an east-west-trending pericline at different levels in the Bentaillou mine in Ariege, France, show that the Ordovician formations of the mine area have been deformed into a series of vertical segments at depth and that this deep compression diminished upward, with the result that the upper beds did not participate in rotational movements.
Observations sur la chromite du mont Ahito (Togo)
Authors: Gsell Alain , Charrier Jacques
Published: March 2020

The chromite mineralization of Ahito, one of a series of small serpentine massifs in French Togo, is shown to have been emplaced in discontinuous lenticular veins, under pneumatolytic-hydrothermal conditions, along north-south fractures paralleling the main structural trend of the massif.
Revision de l'Albien de la region du Havre; deductions paleogeographiques sur le NW du bassin parisien au Cretace moyen
Authors: Destombes Pierre
Published: March 2020

Revision of the Albian (Cretaceous) ammonite faunas of Le Havre region, France, and stratigraphic comparison of the ammonite zones and subzones with those in sections in adjacent regions show that during the middle and upper Albian and the Vraconian, marine transgressions in Normandy were contemporaneous with emergence in the Boulogne region, and vice versa.
Les phenomenes metamorphiques en Limousin septentrional et leur interpretation dans le cadre du Massif Central
Authors: Chenevoy Maurice
Published: March 2020

The crystalline schists of northern Limousin, France, are polymetamorphic in origin. Two phases of migmatization have been distinguished, of different chemical nature and separated by a long time interval. This double metamorphism is not limited to northern Limousin, but is a general characteristic of other parts of the Central Massif and of the metamorphic terrain of Brittany. The classic scheme of metamorphic zoning of migmatites does not hold; rather than an advancing front of migmatization two distinct processes took place at different times--granitization, consisting essentially of partial or total remobilization of preexisting materials, and regional feldspathization, involving K-metasomatism, both represented by independent facies.
Reflexions sur les bases du Quaternaire marin
Authors: Gigout Marcel
Published: March 2020

Both eustatic changes of level and tectonic deformation are responsible for the present position of Quaternary marine deposits. Variations due to retreat of the glaciers, epeirogenic crustal movements, isostatic adjustment, and other processes are discussed. Although the stable plateau region of Morocco has been subjected to slight epeirogenic deformation and therefore cannot be used, as was hoped, as an absolute record of eustatic fluctuations in the early Quaternary, it nevertheless is a particularly favorable place to study glacioeustatic (climatic) pulsations. Six such pulsations have been identified so far.
Les granites stratoides du pays Betsileo (Madagascar)
Authors: Emberger Andre
Published: March 2020

Outcropping granites in the Precambrian crystalline schists of the Betsileo region, central southwestern Madagascar, frequently occur in interstratified shells. These granites are foliated and grade into coarsely banded migmatitic rocks; their structure is granoblastic. The granitic facies are alkaline, whereas the migmatites are calcalkaline. Chemical comparison with the surrounding gneisses shows that the granitization is the result of alkaline metasomatism of the gneiss. The exchanges affect only 6 to 12 percent of the cations of the standard cell. These granites probably date from the Eocambrian orogeny.
Comparaison des conditions de sedimentation et du comportement tectonique des assises du Trias dans les zones externes et internes des Alpes francaises
Authors: Sarrot-Reynauld Jean
Published: March 2020

Study of the stratigraphic and structural relationships of the Triassic formations in the outer and inner zones of the French Alps shows that structures produced during the final stages of Hercynian tectonic activity exerted considerable influence in the evolution of both zones. Differences in tectonic style can be explained by the fact that in the outer zone the gypsiferous Triassic beds were imprisoned in grabens and prevented from flowing, whereas in the inner zone they were not thus restricted.

L'Edough-Cap-de-Fer (Algerie), ile pliocene [with discussion]
Authors: Lambert Alexis
Published: March 2020

Fossiliferous marine Pliocene deposits outcropping over a large area on the southern flank of the Belelieta hills, in the region south of the Edough massif and bordering the Bone plain, Algeria, are characterized by a coarsely conglomeratic facies. The material forming the deposits was derived from crystalline basement rocks. Together with Pliocene deposits of the Cap-de- Fer region they apparently represent an island in Pliocene time. Violent tidal currents in the narrow channel separating the island from the mainland probably explain slightly aberrant details of sedimentation.
Les gneiss oeilles granitises (migmatises) de la vallee de la Vall, massif de l'Albere
Authors: Guitard Gerard
Published: March 2020

During the field excursions of the Societe Geologique de France in the eastern Pyrenees in September 1958, migmatized augen gneisses of the Vall valley in the Albere massif were observed. The gneisses have been subjected to incomplete, heterogeneous, and diffuse granitization.
Le versant sud des Alberes
Authors: Fontbote Jose Maria , Garcia-Rodrigo B.
Published: March 2020

The geology of the south flank of the Alberes range (Spanish slope of the Pyrenees) is outlined, with special reference to data of significance for the field excursion of the Societe Geologique de France in the eastern Pyrenees in September 1958. Three distinct units are present--a Hercynian complex composed of granitized, metamorphosed, and dislocated lower Paleozoic formations; the post-Hercynian sedimentary series, with Mesozoic and Eocene formations, deformed by Alpine crustal movements; and Pliocene-Quaternary formations.
Contribution a la classification des brachiopodes; le lophophore des collolophides nov. ord
Authors: Termier Henri , Termier G.
Published: March 2020

The articulated brachiopods are divided into three orders on the basis of the shape of the lophophore--helicolophids, with spherical lophophore; taeniolophids, with narrow banded lophophore; and collolophids, in which the lophophore is joined for part of its length to the interior of the brachial valve. In the collolophids, in particular, forms whose visceral space is limited tend to have a folded lophophore. Descriptions of Leptodus nobilis and Gubleria disjuncta n.g. n.sp., oldhaminids belonging to the collolophid order, from Cambodia are appended.
Note sur la geologie des environs d'Arcy-sur-Cure et de Saint-More (Yonne)
Authors: Megnien Francoise
Published: March 2020

The abrupt change in dip of Rauracian (Jurassic) deposits in the vicinity of Arcy-sur-Cure and Saint-More in Yonne, France, is not due to tectonic dislocation but to differences in the dip of the terminal zone of a Rauracian reef and that of the surrounding marls.
Etude hydrogeologique du cours inferieur de la Moselle en France; apercu stratigraphique, tectonique et petrographique; resultats des travaux de sondages du barrage d'Apach
Authors: Laugier Raymond
Published: March 2020

The microfacies of the Voltzia sandstone (Triassic) are described in detail, on the basis of information from borings at the Apach dam site in the lower Moselle valley, France. Marls of Keuper facies are intercalated in the formation, which consists partly of sandy and partly of dolomitic beds (both of which are oolitic). Marine influences are evident. Mineralized ground water and a network of faults present difficulties for the dam project.
Resultats du sondage Murviel 1 de la Compagnie d'exploration petroliere; leur apport a la connaissance tectonique de la region de Montpellier
Authors: Gottis Maurice
Published: March 2020

The section traversed by a borehole in the core of the anticlinorium called the "Montpellier fold" permits analysis of the amount of northward displacement of the Jurassic range of the Montpellier region, France. This, together with information from earlier borings, shows that the Montpellier fold, the Gardiole area, and the Montbazin trough all constitute components of the same element of the sedimentary cover, which slid northward as a unit in very late Eocene time; its dip may be as much as 25 degrees N.

Remarques sur la charniere des Erycinacea et des Cyamiacea
Authors: Chavan Andre
Published: March 2020

A complete revision of the closely related pelecypod superfamilies Erycinacea and Cyamiacea has neither confirmed nor refuted hypotheses concerning their origin and supposed degeneration, but it has revealed the wide range of possible arrangement of the lucinoid type of hinge, from its nepionic expression to its accommodation to the intrusion of tooth 1. These arrangements are manifested in a very different order from that postulated by Douville; they are stable within families and support the divisions recognized by Dall and Cossmann. The Erycinacea and Cyamiacea therefore are not a haphazard grouping of baffling forms, but two rather ancient superfamilies of the heterodonts that can be classified in an orderly manner in spite of their great diversification.

Les problemes de la cartographie internationale des plissements et la feuille d'Algerie-Tunisie de la carte tectonique d'Europe
Authors: Caire Andre , Glangeaud Louis , Mattauer Maurice
Published: March 2020

the major structural units of the Algerian-Tunisian region, from south to north and from lowest upward, are the pre-Saharan units, corresponding to the autochthonous basement and comprising a Paleozoic craton and its cover; the intra-Tellian autochthonous complex; the semirigid Kabylian structure and its cover; the plastic Tell nappes; and the post-nappe Mio-Plio-Quaternary cover. Each of these units is described, the autochthonous, parautochthonous, and allochthonous units of the Tell region, Algeria, are defined, and the evolution of the Alpine orogeny in Algeria is outlined as a guide for the selection of symbols for representing the units on the Algerian Tunisian sheet of the international tectonic map.
