摘　　要：八家子地区自然铜矿化体赋存于中生代侏罗系土城子组(J 3t)凝灰质砂岩、砾岩中,受断裂构造控制,其中碳酸盐化、高岭土化、褐铁矿化及硅化与自然铜矿化关系密切。初步分析认为八家子地区自然铜矿化属于低温热液矿床,多期次成矿,与断裂构造有明显的成因联系。同时指出在中生代侏罗系土城子组(J 3t)凝灰质砂岩、砾岩中寻找断裂是下一步的重要找矿方向。The natural copper mineralized body in Bajiazi area,occurs in tuffaceous sandstone and conglomerate of the Jurassic Tuchengzi Formation(J3t)in Mesozoic,which is controlled by fault structure.Carbonation,Kaolinization,Ferritization and Silicification are closely related to the natural copper mineralization.The preliminary analysis shows that the natural copper mineralization in Bajiazi area belongs to the low temperature hydrothermal deposit,which is multi-stage mineralization and has obvious genetic relationship with the fault structure.At the same time,it is pointed out that the next important prospecting direction is to find faults in the tuffaceous sandstone and conglomerate of the Jurassic Tuchengzi Formation(J3t)in Mesozoic.
