摘要
深部隐伏酸性岩体形成(或侵入)产生的含矿气水热液沿断裂向上运移,在特定地质条件下反复充填交代成矿。地下水渗透或环流则从围岩或先期形成的矿床中溶解出矿质,在有利条件下沉积,形成地下水热液矿床或与先期矿床叠加。
The ore- bearing gas- water thermal fluid formed by the formation （intrusion） of deep blind acid rock body migrates upwards along the fault, forms ore deposit by repeated filling metasomatism under the specific geological condition. The seepage or circulation of underground water solutions and extracts metallogenetic material from wall rock or ore deposit formed early, deposits under the advantageous conditions and forms the underground hydrothermal ore deposit or superimposes on the preexisting ore deposit.
