摘要
琅琊山铜矿为一广义上的层控夕卡岩型铜矿床,其关键控矿因素是S形旋扭褶皱构造、蘑菇状岩体形态及特定的赋矿层位。近年来利用人工受控定向钻探新技术在该地区开展的深部找矿,取得了很好找矿成果,证实了石英闪长玢岩体底部接触带的存在且具有良好的含矿性,对本区深部及外围找矿具有重要意义。
The Lanyashan copper deposit is a strata-bound skam copper deposit in broad sense and key ore-control factors are °∞S°±twisted folding structure, mushroom-like rock body and specific ore-host horizon. In recent years, artificially controlled directional drilling technology was applied to deep-seated ore prospecting in the area and brought very good result, proving that existence of contact zone at the bottom of quartz diorite poyphyrite and its good ore-bearing performance are important to ore prospecting in the depth and periphery.
