Mammalian fossils from two principal collecting areas in the lower Hanna Formation of the Carbon Basin comprise three faunas, the Grayson Ridge, Halfway Hill, and Sand Creek faunas. The Grayson Ridge and Halfway Hill faunas are diverse, consisting cumulatively of 29 mammalian species, at least two of which are new. The faunas are approximately equivalent in age and are either latest lbrrejonian...

The Andaman and Nicobar ophiolites, in the forearc of western Sunda subduction zone, underwent enigmatic, rapid Cenozoic vertical motions: shallow-water sediments with abundant arc debris characterize middle Paleocene–middle Eocene are under- overlain by significantly deeper sediments. Recent paleomagnetic results revealed a near-equatorial paleolatitude West Burma Block associated at similar l...

[1] Previous workers identified a magnetically anomalous clay layer deposited on the northern United States Atlantic Coastal Plain during the Paleocene-Eocene thermal maximum (PETM). The finding inspired the highly controversial hypothesis that a cometary impact triggered the PETM. Here we present ferromagnetic resonance (FMR), isothermal and anhysteretic remanent magnetization, first-order rev...

Abstract Besides nitrate deposits located in the Atacama Desert of Chile and Mojave California, present work documents, for first time, occurrence potassium as oval-suboval-shaped aggregations associated with Late Maastrichtian-Early Paleocene Dakhla Shale Paleocene-Early Eocene Esna encountered northeastern part Kharga Oasis, particularly at G. Um El-Ghanayem Ghaneima. Consequently, integrated...

The Carboniferous–Palaeogene Wandel Sea Basin of eastern North Greenland (north 80°N, east 40°W) is an important piece in the puzzle Arctic geology. It particularly for understanding how Paleocene–Eocene convergence between Greenland, Canadian and Svalbard relates to compressional tectonics High Arctic, collectively known as Eurekan Orogeny. In this study, we present apatite fission-track analy...

The Yarkand Basin, located in the southwest of Tarim is a northeastern part eastern Paratethys ocean Paleocene, and significant amount evaporites, with gypsum, anhydrite, halite as main types, were developed this area. These evaporites record sedimentary environment at that time. A study was conducted on sulfur isotopic composition gypsum Paleocene Basin to explore origin interpret environment....

2D multi-channel seismic profiles and a 3D survey were utilised together with potential field available well data to study the late Mesozoic-Cenozoic tectono-stratigraphic evolution of northern Lofoten-Vesterålen margin, offshore Norway. The analysis resulted in an updated structural stratigraphic framework, new better refined elements. Distinct along-margin basin segmentation is evident impose...
