The Sanjiang Tethys tectonic domain is one of the major metallogenic belts in China. The magmatism and metallogeny in this region have been variously attributed to break-off of the subducted slab, delamination of the lower crust or lithosphere, and mantle plume upwelling. Previous seismic studies have identified prominent heterogeneity of velocity structure in the crust and mantle in this region....

A large part of these belong to the late Mesozoic gold deposits in the North China Craton (NCC) that occur along craton margins, as well as within the cratonic interior in reactivated paleo sutures, and show a close spatio-temporal relationship with...
