摘要
黑龙江老柞山大型金矿床由东、中、西矿带组成,东矿带矿体产于兴东群大马河组中,中矿带矿体产于元古代混合花岗岩与混合岩接触带矽卡岩中,西矿带矿体产于元古带混合花岗岩内。金矿床的形成经历了混合岩化作用,韧性剪切作用及岩浆热液叠加的成矿过程。
Heilongjiang Laozuoshan large gold deposits consist of the east central and western bell witheast belt ore produced in Xingdong Dama Creek group, central bell ore produced in proterozoic granite and migmatite mixed skarn contact zone, and western belf produced in proterozoic mixed gran ite. The formation of gold deposits experienced the mineralization process of migmatization, ductile shearing and magmatic hydrothermal superimposition.
