摘要 The Southern Great Xing'an Range,Northeast China,is located in the eastern part of the Central Asian Orogenic Belt.It is considered to be one of the most important metallogenic belts,commonly hosting a series of skarn.porphyry and magmatic hydrothermal Pb-Zn-Ag-Cu Mo-Sn polymetallic deposits(Fig.1).Complex tectonic events have occurred in this region,including the closure of the Palco-Asian Ocean in the Late Palaeozoic,the opening and closure of the Mongol Okhotsk Ocean and the subduction of the Paleo-Pacific Ocean in the Mesozoic.
