Late Permian back-arc basin development in the western Jinshajiang suture zone, Central Qinghai-Tibetan Plateau: evidence from the Yushu mafic-ultramafic rocks

摘要：

　　The Central Qinghai-Tibetan Plateau (CQTP) is mainly characterized by the development of the Palaeo-Tethyan tectonic-magmatic system, which involved complex evolutionary processes of multiple terranes and suture zones, and provides an important window into understanding Palaeo-Tethyan tectonic evolution and mineralization of the Qinghai-Tibetan Plateau and elsewhere.The Jinshajiang Suture Zone (JSZ) is generally considered as an extremely important feature in the CQTP.However, the nature of the JSZ and the way it extends westward remain hotly debated (e.g.Wang et al., 2000;Reid et al., 2005;Metcalfe, 2006;Pullen et al., 2008;Fan et al., 2010;Yang et al.,2012).In this paper, we provide new geochronological, geochemical and isotopic data for the Yushu mafic-ultramafic rocks in the western JSZ that help to constrain the Palaeo-Tethyan tectonic evolution of the CQTP.
