辽宁大板金矿床地质特征及找矿前景

矿床位于辽西台陷北缘，受ＮＥ和ＥＷ向断裂控制，属著名的排山楼金矿外围。前寒武纪斜长角闪岩是主要矿源层。断裂构造为成矿提供空间。金矿化与蚀变带关系密切，蚀变越强金含量越高。属韧性剪切带型金矿，糜棱岩化、斜长角闪质岩石和构造交汇部位是寻找金矿的重要标志。与排山楼金矿对比表明该地区具有找矿前景。

Geological charateristics and prospecting of Daban gold deposit in Fuxin, Liaoning

The deposit is located in the north margin of platform subside in west of Liaoning. It is controlled by NE EW trending faults, belongs to the peripheral deposit of Paishanlou gold deposit. The main source bed is Precambrian plagioamphibolite, and the faulted structure provides the space for the mineralization. Gold mineralization is closely related to the alteration zone. Gold content is higher when the alteration is stronger. The deposit belongs to ductile shear zone type. Mylonitized, plagioamphibolite and crossing area of faults are the important signs for gold exploration. Comparing with Paishanlou gold deposit, it indicates that there is prospective for gold exploration in this area.
