摘　　要：作者依据获得的直接证据 (首次发现的含矿喷气岩等 )和间接证据 (组构标型、矿物标型及同位素标型等 ) ,并应用活动论的观点确认天宝山岩块、早二叠世庙岭组、红叶桥组是主要的含矿层 ,每一岩浆单元晚期的中小斑岩是含矿岩。其中的成矿物质在火山喷气、岩浆爆破和断裂构造的热动力驱动下活化并参与成矿 ,这样就使富含成矿物质层 (岩 )真正变成矿源。On the basis of the direct data (discovered gas-bearing exhalite for the first time) and indirect data (typomorphic fabric, typomorphic mineral and typomorphic isotope) and the theory of the continental activity, it is confirmed that the Tianbaoshan block, early Permian period Miaoling Formation, Hongyeqiao Formation are primary ore-bearing bed, which the late-staged mid-small porphyry of each magmatic unit is the ore-bearing rock. Among them the metallogenic materials were actived and mineralized by the volcanic exhalation, magmatic explosion and thermal drive of faulted structure, so, making the rich mineral-bearing strata (rocks) come real metallogenic resources.
