Unraveling the Lhasa‐Qiangtang Collision in Western Tibet: Insights From Geochronological and Paleomagnetic Analyses

“…The marine environment in western Qiangtang started during the Late Triassic‐Early Jurassic and was ceased by the Late Jurassic, with marine rocks unconformably overlain by Upper Cretaceous continental red beds (A. Ma et al., 2017). In contrast, the marine environments in western Lhasa continued to develop until Mid‐Cretaceous (Rao et al., 2020). The arrival of Qiangtang detritus into western Lhasa basins at ∼111–116 Ma marks a minimum age for the initial Lhasa‐Qiangtang collision (S. Li et al., 2019).…”

Stratigraphic and taxonomic considerations on the Late Cretaceous rudist fauna of Aksai Chin (Western Tibet, China) from the De Filippi Collection

“…Rudist faunas from the Himalaya-Karakorum-Tibet range and the Tarim basin are known from the late Aptian and are well-developed into the Maastrichtian (LAN & WEI, 1995;WEN et al, 1998;SCOTT et al, 2010;RAO et al, 2015RAO et al, , 2017RAO et al, , 2020SHA & CESTARI, 2016;RAO, 2019). SCOTT et al (2010) reported 36 genera and 44 species occurring in the region in the Albian-Maastrichtian interval.…”
