山东平邑卓家庄金矿构造控矿因素及其意义

STRUCTURE CONTROLLING ORE FACTORS AND IMPLICATIONS OF ZHUOJIAZHUANG GOLD DEPOSIT,PINGYI,SHANDONG PROVINCE

平邑卓家庄金矿是一隐爆角砾岩筒型金矿床 ,矿区内断裂构造发育且具有多期活动的特点 ,NW向和EW向断裂交汇部位控制了角砾岩筒的产出 ,等距性分布的次级断裂控制了角砾岩筒的等距产出 ,断裂的交线产状代表了角砾岩筒的产状 。

Zhuojiazhuang gold deposit is a type of hydrothermal breccia pipe gold deposit. Fault structures are spread in ore area and characterized by molystage activities. The fault intersection segment of NW- striked fault and NE- striked Fault controlled the occurrence of breccia pipe, second-order faults which distributed isodistantly controlled the equidistant occurrence of breccia pipe. The occurrence of the intersection line of faults represented the occurrence of breccia pipe and is the important evidence of location prognosis of ore body.
