in this research, biostratigraphy and paleo-ecological reconstruction of the qom formation deposits in bijegan village, northeast ofdelijan, are discussed. the studied section is situated in the western margin of the urumieh-dokhtar magmatic arc (the intra-arc basin).the qom formation deposits at the studied area are rupelian-chattian in age. larger benthic foraminifers are used for biostratigr...

Abstract. Intrusion of deep saline waters into freshwater aquifers does not only endanger the regional drinking water supply, but also rivers and stagnant their fauna are threatened by salinisation. The upwelling highly mineralised in large parts North German Basin is favoured presence Elsterian glacial erosion windows Lower Oligocene Rupelian Clay, most important hydraulic confining unit this ...

Abstract In contrast to other kinds of biological interactions, symbiosis is a scarcely investigated aspect the fossil record. This largely due taphonomic biases that often frustrate any attempt make strong case two organisms shared an intimate association in life. Among extant marine vertebrates, sea turtles (Cheloniidae and Dermochelyidae) bear broad diverse spectrum epibiotic symbionts, incl...

Changes in sedimentary profiles and stratigraphic architecture over time lake basins are shown to be relevant markers of climate changes terrestrial palaeoenvironments. The the Priabonian (late Eocene)–early Rupelian (early Oligocene) Alès–Saint-Chaptes–Issirac saline system has been reconstructed from sedimentological, biostratigraphic magnetostratigraphic analysis outcrops well cores. As a fu...

Abstract This paper provides an understanding of the sedimentary-tectonic evolution Cenozoic strata El Habt and Ouezzane Tectonic Units (Intrarif, External Rif) in Morocco. New data provide information about depositional architecture enable a correlation Rif Morocco with that Betic Cordillera Spain Tunisian Tell, which new insights for hydrocarbon exploration region regarding possible source, r...
