DOI: 10.1007/s00410-017-1364-y

Abstract: The microstructures, major- and trace-element compositions of minerals and electron backscattered diffraction (EBSD) maps of high- and low-Cr# [spinel Cr# = Cr3+/(Cr3+ + Al3+)] chromitites and dunites from the Zedang ophiolite in the Yarlung Zangbo Suture (South Tibet) have… read more here.

DOI: 10.1007/s00531-018-1646-2

Abstract: An integrated investigation of Lower Jurassic Jialapu Formation (including U–Pb dating of igneous and detrital zircons, geochemical analysis of igneous rocks, and analysis of detrital modes of sandstone interbeds) in the southern margin of the… read more here.

DOI: 10.1016/j.gr.2021.04.007

Abstract: Abstract The co-existence of Cretaceous adakitic and A-type granitoids in southern Tibet can offer fundamental constraints on subduction of the Neo-Tethyan oceanic plate and associated crustal growth processes, if their petrogenetic relationships are understood. Here,… read more here.

Compositional and geochronological signatures of metamafic dykes from the Sangsang peridotites, South Tibet: Evidence for magma-starved forearc rifting during Neo-Tethyan subduction re-initiation

DOI: 10.1016/j.gsf.2020.02.015

Abstract: Abstract In this study we present new mineral chemistry, whole-rock geochemical and zircon U–Pb geochronological data for 12 metamafic dykes in the mantle sequence of the Sangsang ophiolite in South Tibet (China). Modal analyses of… read more here.

DOI: 10.1016/j.oregeorev.2020.103581

Abstract: Abstract The petrography and compositions of chromitites and peridotites from the Tibetan Luobusa ophiolite, a fragment of Neo-Tethyan forearc lithosphere, are used to study the origin of high-Cr chromite deposits and relevant magmatic evolution in… read more here.
