Based on the study of Luocun rock mass in terms of lithology,lithochemistry,trace element,in-clusion thermometry and isotopic dating,it is indicated that Luocun rock mass is a kind of low-to-moderate temperature supergene acidic porphyry of late Yanshanian.The content of trace elements like Cu,W and Mo in the zonal breccia of rock mass is 12 times higher than that in rocks of the same category such as K. Tulchian rocks,while the content of Mo is 30 times higher.Obviously,the degree of mineralization is rela-tively high in the rock mass and the ore-forming environment is favorable.Luocun rock mass occurs in an ex-tensional tectonic environment and its ore-formation has close relationship with the breccia inside the rock mass.This research has great significance to future prospecting works in this area.
