摘要
大田银场矿区银多金属矿产于燕山早期第三阶段第一次侵入的二长花岗岩体中,受燕山早期北东东向断裂构造控制,矿体呈脉状、透镜状产出,区内矽卡岩化发育地段是矿体富集部位,矽卡岩化与印支-燕山期推覆构造关系密切,属于中-低温热液充填-交代型银多金属矿床。
Silver polymetallic deposits lies in monzonitic granite of early yanshanian stage III for the first time penetrated, and is controlled by the Yanshan early NEE faults. The orebodies are in the vein and lenticular, Silicon skarnization development section is enriched local ore body. Silicon skarnization closely related to indochina- yanshan nappe structure, it belongs tomeso-epithermal hydrothermal filling silver polymetallic deposit.
