摘要
在分析板庙子金矿地层、构造、岩浆岩等控矿因素的基础上,总结区内的找矿标志,建立成矿模式,从而进行靶区预测。研究表明:板庙子金矿区矿体的产出受东西向挤压破碎带控制;Au、Bi元素的成矿主要与辉绿岩、煌斑岩和花岗斑岩岩脉的就位有关,Ag、Zn、Cu、Pb等元素的矿化主要与闪长玢岩和二长花岗斑岩的就位有关。在此基础上,研究区内共圈定靶区4处。
Based on analyzing the strata,tectonics,magmatite and other ore-controlling conditions in Banmiaozi district,the paper concluded the ore-propecting criteria,built the metallogenic model in order to carry out the target prediction.Studies showed that the occurrence of gold orebodies were controlled by the E-W compressive rupture zone.The mineralization of Au and Bi was related to the dolerite,lamprophyre and granite porphyry vein.While,the mineralization of Ag,Zn,Cu and Pb was related to diorite-porphyrite and granite porphyry vein.Finally,the authors delineated four prospecting targets in the district.
