     Located in the interior of South China, the Qin-Hang( Qinzhou Bay to Hangzhou Bay) metallogenic belt was formed by the collision between the Yangtze craton and the Cathaysian block in late Neoproterozoic. In this paper, these two kinds of granitic source rocks were compared with each other in such aspects as spatial-temporal distribution, chronology, geochemical, Sr-Nd isotopic characteristics and tectonic settings. The former was derived locally from the remelting of subducted ancient Pacific plate along the Qin-Hang fault zone, whereas the latter was resulted from subducted plate windows in the central part of South China in a continental crustal extension and thinning setting. Abundant mantle materials were involved during the two types of rock-forming and ore-forming processes. Nevertheless, less mantle materials were involved in the formation of Late Jurassic granitoids related to W-Sn deposits.
