Continental reconstruction and metallogeny of the Circum-Junggar areas and termination of the southern Central Asian Orogenic Belt
Abstract
Continental reconstructions in Central Asia are represented by orogenesis along some large orogenic belts in the Altaid collage (Fig. 1) or Central Asian Orogenic Belt (CAOB), which separate the East European and Siberian cratons to the north from the Tarim and North China cratons to the south (Şengör et al., 1993; Jahn et al., 2004; Windley et al., 2007; Qu et al., 2008; Xiao et al., 2010; Xiao and Santosh, 2014). The Altaid Collage was characterized by complex long tectonic and structural evolution from at least ca. 1.0 Ga to late Paleozoic-early Mesozoic with considerable continental growth (Khain et al., 2002; Jahn et al., 2004; Xiao et al., 2009, 2014; Kröner et al., 2014), followed by Cenozoic intracontinental evolution related to far-field effect of the collision of the Indian Plate to the Eurasian Plate (Cunningham, 2005). Accompanying with these complex geodynamic evolutions, many world-class ore deposits developed (Qin, 2000; Yakubchuk et al., 2001; Goldfarb et al., 2003, 2014).
