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代混合花岗岩内。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。
The large scale gold deposit of Laozuoshan comprises of three mineralized belts i.e.,the eastern,the middle and the western belts.The orebodies in the eastern belt occur in Damahe Group of Xindong Formation,The orebodies in the middle belt occur in skarn rocks in the contact between migmatitic granite and migmatite of Proterozoic Era. The formation of the gold deposit had undergone the process of migmatization,ductile sheering and magmatic hydrothermal superimposition.
