AbstractAbstract
[en] During years 1985-1988 various non-clay geochronometers have been searched for, discovered, and analysed. Biostratigraphic, sedimentologic, chemostratigraphic, magnetostratigraphic and geochronologic studies were undertaken. Independent laboratories working in diverse basins from Europe or the Americas have obtained well documented numerical datings. The obtained data are internally consistent and allow precise estimates for some boundaries; these estimates obtained from radiometric data, generally confirm previous similar exercises including those where glauconies were considered. The dates calculated until now using the sea floor anomaly sequence and relative width interpolation system are not consistent with radiometrically derived intervals of time for the boundaries where enough data are available. Although systematic, differences between the two sorts of estimates are locally small, and a revision of the present application should be considered. According to the recently obtained data, the Cretaceous-Tertiary boundary is 64 to 65 Ma old and the Eocene/Olgocene boundary is located confidently in the interval of time: 33.7 ±0.5 Ma. 46 refs

Au cours des quatre annees 1985-1988, divers geochronometres non argileux, ont ete recherches decouverts et analyses. L'application au calibrage de l'echelle des temps a necessite des etudes biostratigraphiques, sedimentologiques, chimiostratigraphiques, magnetostratigraphiques et geochronologiques. Une serie d'ages numeriques a ete obtenue par divers auteurs dans divers bassins d'Europe et d'Amerique. Ces ages sont coherents et precisent les estimations anterieures etablies d'apres les datations isotopiques incluant les ages sur glauconie. Les estimations d'age proposees jusqu'ici a l'aide d'extrapolations a partir de la sequence magnetique mesuree au fond des oceans ne se trouvent pas confirmees, dans la mesure ou les ages extrapoles sont en dehors des intervalles de temps definis par les datations; cependant, les differences sont localement etonnemment faibles et invitent a reviser le principe d'evaluation de ces estimations. D'apres les datations recentes, la base du Paleogene est assez precisement situee entre 64 et 65 Ma et la limite Eocene/Oligocene dans l'intervalle 33,7 ±0,5 MaOriginal Title

AbstractAbstract
[en] A new benthic foraminifer is described as Glomospirella cantabrica n. sp. from several sections of the upper Aptian Reocín Formation and one occurrence from the lowermost Albian Las Peñosas Formation of Cantabria (northern Spain). It represents a rather large-sized Glomospirella, with up to eight planispiral whorls, observed in lagoonal wackestones and packstones. The upper Aptian (upper Gargasian–Clansayesian) age is indicated by the co-occurrence with other benthic foraminifera, i.e. orbitolinids. Further biostratigraphic data of the Aptian-p.p. Albian shallow-water carbonates of the North Cantabrian Basin is provided. The rareness of dasycladalean green algae in these deposits is also highlighted. The resulting stratigraphic and biostratigraphic scheme is integrated in a framework of depositional sequences of the North Cantabrian Basin and compared with the sequential schemes of other areas of the Basque-Cantabrian Basin and the Iberian Chain. Similitudes suggest that these depositional sequences are related to global sea-level changes. (Author)

AbstractAbstract
[en] The Palo Duro Basin, Permian Basin, Texas is an asymmetric, relatively shallow, intracratonic basin in the southern Texas Panhandle filled mostly by Mississippian, Pennsylvanian, and Permian sedimentary rocks. Although deeper and prolific prolific petroleum-producing basins adjoin it on the north (Anadarko Basin), south (Midland Basin), and east (Hardeman Basin), the Palo Duro Basin has produced remarkably small amounts of oil and gas to date. This is all the more noteworthy because the sedimentary sequence and rock types of the basin are similar to those of the adjacent basins. Analyses of the stratigraphic succession and structural configuration of the Palo Duro Basin suggest that adequate reservoir rocks, top-seals, and geologic structures are present. Most of the structures formed early enough to have trapped hydrocarbons if they were migrating in the rock column. Although additional work is under way to properly address the question of the petroleum source rocks, generation, and migration, the general absence of production in the basin may relate to an overall deficiency in hydrocarbon generation within the basin. Geologic information in this report will form part of the basis for further analysis and conclusions on hydrocarbon potential in the Palo Duro Basin

AbstractAbstract
[en] The Permian megafloras of Uruguay. A synthesis. An analysis of the impression and fossil wood floras from the Permian of Uruguay is given through a series of Tables. These show : (1) the list of taxa, (2) anatomical characters of the woods, (3) data on the microfloral associations, (4) paleoenvironmental information and (5) comparisons with contemporaneous Gondwana floras. The evolutionary degree of the woods is briefly analyzed where they correspond to the so-called ''transition xilotaphofloras'' as they present typical Paleozoic anatomical characters but with secondary xylem of more advanced characteristics.
