Upper Jurassic–Lower Cretaceous stratigraphy in south-eastern Tibet: a comparison with the western Himalayas

Testing the validity of Nd isotopes as a provenance tool in southern Tibet for constraining the initial India–Asia collision

“…Rilang Formation in Gyangze (Hu et al, 2008), and the Tianba Flysch near Kangmar (Zhu et al, 2004). Similar Lower Cretaceous volcaniclastic rocks have been documented widely in the western Himalaya, including Zanskar and Kumaon in India (Garzanti, 1991) and the Thakkhola Graben in northern Nepal (e.g., Garzanti, 1999).…”

“…2). The northern zone (Gyangze-Saga areas) is mainly dominated by Mesozoic to Paleogene deep-water sedimentary deposits of the outer shelf, continental slope, and rise (Hu et al, 2008).…”

“…2);(2) the Gucuo section, Tingri (GPS N28°46 0 56'', E86°19 0 13''), following the stratigraphy ofHu et al (2008Hu et al ( , 2010 (Fig. 2); and (3) the Chuangde section (GPS N28°57 0 56'', E89°44 0 20''), following the stratigraphy ofLi et al (2005) andHu et al (2008) (Fig.…”

“…The stratigraphy in the Tingri area is fromWang et al (2002),Zhu et al (2005), andHu et al (2010). The stratigraphy in the Gyangze area is fromLi et al (2005) andHu et al (2008).…”

Nannofossil biostratigraphy of the Lower Cretaceous Shadui Formation (Northern Tethyan Himalayas, Southern Tibet)

“…The line of subdivision has been placed along the Gyrong-Kangmar thrust (Ratschbacher et al 1994), or alternatively along the Gamba-Tingri fault (Wang et al 1996). The Southern Tethyan Himalayas are characterized by shallow shelf sedimentary rocks of the Paleozoic, Mesozoic and Cenozoic (up to Eocene) age (Yang & Wu 1962;Xu et al 1990;Willems et al 1996), while the Northern Tethyan Himalayas are represented by sediments deposited on the continental slope and in the adjacent deep oceanic basin (Searle et al 1987;Liu & Einsele 1994;Jadoul et al 1998;Hu et al 2008). The Bangbu section tectonically belongs to the deeper, Northern Tethyan Himalayas (see Fig.…”
