摘要
华力西期次火山活动及同熔岩浆侵入活动为马庄山金矿提供了中低温含金热液，前寒武纪结晶基底、石炭系白山组英安质凝灰岩及石英斑岩（次火山岩）为矿源层。横贯矿区的两条北东向主干断裂（Ｆ３１２、Ｆ３１３）为导矿构造，次火山岩内张性断裂及主干断裂派生的张扭性断裂为主要容矿、控矿构造。今后找矿工作中应侧重深部找矿。
The auriferous fluid of middle-low temperature is supplied by the subvolcanic activity of variscian stage and the intrusion activity of syntectic magma.The crystalline basement of Pre cambrian,the dacitic tuff and quartz prophyry(subvolcanic rock)of Baishan Group in carboniferous system are source beds.Two NE major faults(F 312 ,F 313 )crossing gold deposit are structures as passage way for ore fluid.The tensional faults in the subvolcanic rock and the tensional-trosional faults,which are induced faults of major faults,are host structures and ore-control structures.Finding for deep orebodies is the future prospecting targets.
