The Central Asian Orogenic Belt (CAOB),also referred to as the Altaid collage or the Altaids,is situated among the Siberia,East European,Tarim,and North China cratons (Seng(o)r et al.,1993;Yakubchuk,2004).The CAOB was mainly formed by subduction,terrane accretion,craton collision,and post-collisional extension from the Neoproterozoic to the end of the Paleozoic (Windley et al.,2007;Xiao et al.,2010).The Irtysh-Zaysan Ocean,existed between the Kazakhstan and Siberia blocks during the Devonian and Early Carboniferous (Iwata et al.,1997),with the Altai orogen defining the southern margin of the Siberia block,to the north,and the Zharma-Saur volcanic arc along the northern margin of the Kazakhstan block,to the south (Windley et al.,2007;Chen et al.,2010;Shen et al.,2012).
