| 摘 要： | 法库城子山一带硅灰石矿床分布在吉黑地槽南缘调兵山背斜，赋存于早古生代富拉堡子岩组与岩体接触带附近，属接触变质型矿床。区域上构成了东、西两个硅灰石矿带。矿石类型有： 致密块状硅灰石－ 方解石－ 石英型， 硅灰石－ 石英型， 巨晶硅灰石－ 方解石型等三种类型。其主要围岩蚀变为硅灰石化、硅化、碳酸盐化、绿泥石化及角岩化，局部见矽卡岩化。富硅灰岩－ 三叠世侵入岩－ 构造裂隙系统是主要控矿因素。

| Abstract: | The wollastonite deposit distributing around Chengzishan at Faku county occurred near the contact belt between Fulapuzi petrofabric of Early Paleozoic and intrusive bodies,belonging to contact metamorphic deposits.There are two wollastonite ore belts in the east and west.The ore types in clude compact massive wollastonite calcite quartz type , wollastonite quartz type and megacryst wollas tonite calcite type. The major wall rock alteration is wollastonitization ,silisification ,carbonation ,chlo ritization , and hornfelization , occassionaly skarnization .The main ore controlling factors are wollas tonite rich rocks,Tertiary intrusive rocks and structural fissures system . |
