Provenance of the Upper Cretaceous–Eocene Deep-Water Sandstones in Sangdanlin, Southern Tibet: Constraints on the Timing of Initial India-Asia Collision

Paleogene monsoons across India and South China: Drivers of biotic change

“…The exact timing of first contact between India and Asia remains controversial but it most likely occurred ~55 ± 10 Ma (Beck et al, 1995;Rowley, 1996;Acton, 1999;de Sigoyer et al, 2000;Aitchison et al, 2002;Ding et al, 2005;Leech et al, 2005;Zhu et al, 2005;Garzanti, 2008;Guillot et al, 2008;Copley et al, 2010;Liebke et al, 2010;St-Onge et al, 2010;Cai et al, 2011;Wang et al, 2011;Hu et al, 2012; A C C E P T E D M A N U S C R I P T…”

Petrogenesis of the early Eocene I-type granites in west Yingjiang (SW Yunnan) and its implication for the eastern extension of the Gangdese batholiths

“…Also shown in (a) are the data for granitoid rocks from the Gangdese belt (i.e., Debon et al, 1986;Harris et al, 1988b;Wen et al, 2008a;Huang et al, 2010) and from the Northern magmatic belt (i.e., Zhu et al, 2009b;Zhang et al, 2010b;Huang et al, 2012), and the Nianbo Formation of the Linzizong volcanic rocks in Tibet (i.e., Mo et al, 2008;Xie et al, 2011;Lee et al, 2012). In (b), the pink and gray fields note those from the Gangdese belt and the Northern magmatic belt ( 1987; Searle et al, 1987;Leech et al, 2005;Najman et al, 2010;Wang et al, 2011). In combination with other data from Klootwijk et al (1992), Hodges (2000), Najman et al (2005Najman et al ( , 2010 and Xu et al (2008), it is most likely that the India-Asia collision commenced at~50-55 Ma or later.…”

To address some of the unresolved issues above, this paper presents a set of new zircon U-Pb geochronological, elemental and Sr-Nd-Hf isotopic data for the gneissic granite and leucogranite from the Nabang metamorphic zone in the Yingjiang area (West Yunnan, SW China).…”

Rapid Eocene erosion, sedimentation and burial in the eastern Himalayan syntaxis and its geodynamic significance

“…The Tibetan-Himalayan orogen was largely created by the IndiaAsian collision at~55 Ma as suggested by multidisciplinary lines of both direct and indirect evidence (Allègre et al, 1984;Patriat and Achache, 1984;Rowley, 1996;Zhu et al, 2005;Chen et al, 2010;Najman et al, 2010;Sun et al, 2010Sun et al, , 2012Cai et al, 2011;Clementz et al, 2011;Wang et al, 2011). Exposures of HP metamorphic rocks within the Himalayan orogen provide crucial insights into the collision, continental subduction and exhumation process (Tonarini et al, 1993;Guillot et al, 1997;Ding et al, 2001).…”
