When and how the collision between India-Asia occurred continue to be debated. We report new paleomagnetic data (Ds = 158.8°, Is 7.8°, ks 81.3, α95 5.1°, N 11 sites) from limestone of Zongpu Formation Member I in Tingri, which indicate that Tethyan Himalaya was situated at 3.9 ± 2.6°S during 62-59 Ma. This implies Greater India ∼900 km did not break off India, left a ∼2,000 Neo-Tethys Ocean cha...

Abstract In Egypt, Wadi Qena Middle Eastern Desert, Paleogene successions exposed at Hawashiya and Abu Had sections from north to south were measured comprehensively investigated for their foraminiferal content. The Dakhla, Tarawan, Esna formations make up the sections. studied are subdivided into six biozones; they five zones of Late Paleocene ( Igorina albeari subzone (P3b), G. Globanomalina ...

The Eocene Peñicas (Almería) and Harania (Málaga) stratigraphic sections from the Malaguide Complex (Betic Cordillera, South Spain) belonging to Mesomediterranean Microplate westernmost Tethys (about-35°N 0° 5°E according coordinates) have been studied. cover Cuisian middle Lutetian deposits, which show several lithofacies representing shallow marine platform realms. Based on fossiliferous asse...

Using the Max Planck Institute for Meteorology Earth System Model, we investigate the forcing of forests and the feedback triggered by forests in the pre-industrial climate and in the early Eocene climate (about 54 to 52 million years ago). Other than the interglacial, pre-industrial climate, the early Eocene climate was characterised by high 5 temperatures which led to almost ice-free poles. W...

The Eocene is the initial stage of Cenozoic global cooling. Compared with abundant marine records, continental records are scarce. Throughout Eocene, a series continuous deposition gypsum and volcanic tuff-bearing red clastic sediments have developed in Nangqian Basin (NB). In this work, representative were collected from NB, lipid biomarkers compound-specific carbon isotopes n -alkanes analyze...

Yuomys are medium-sized Hystricomorpha rodents. They known for coming from areas of low elevation in China during the middle and late Eocene. Two new were discovered a locality near Xueshuo village Litang County, Sichuan Province. The lies Gemusi pull-apart basin formed Fault System (LTFS) Hengduan Mountains. current average is about 4200 m. One two larger shows clear lophodont unilateral hypso...
