Introduction [2] Issued from the Pangea breakup by the end of Paleozoic, Tethys was an oceanic domain having a roughly E-W orientation and separating the continents into two main masses north and south of it, respectively (see a review in the work by Ricou). , Orcutt et al. 1 a; Yin and Harrison, 2000). , 2015), 65–41 Ma (Zhu et al. There are plenty of petroleum resources in the Chinese marine basins, which will be the potential exploration regions of petroleum in the 21st century. It is interpreted as a major component of a continental margin related to the northward subduction of the Neo‐Tethys oceanic slab beneath Eurasia and it is the key in understanding the tectonic framework of southern Tibet prior to the.
