摘要
卡尔却卡铜多金属矿床位于东昆仑祁漫塔格成矿带,为该区近年来发现的最重要矿床之一。本文通过对卡尔却卡铜多金属矿床地质特征及同位素地球化学特征的详细剖析,并结合其成岩成矿时代,认为卡尔却卡铜矿为广义斑岩型矿床,即以侵入体为中心的斑岩型-矽卡岩型矿床,外围赋存于沉积岩内的矽卡岩-热液型矿床和远离岩体的断层破碎带内的浅成低温热液矿床组成的斑岩矿床成矿系。
Kaerqueka copper polymetallic deposit,which was found recently in Qimantage metallogenic belt of East Kunlun of Qinghai province,is one of the most important deposits in its area.An analysis on geological and isotopic-geochemical characteristics of Kaerqueka copper polymetallic deposit and its diagenetic and mineralogenetic age suggests that Kaerqueka copper deposit is a generalized porphyry deposit,namely aporphyry metallogenic system which consists of intrusive body-centered porphyry-skarn type deposits,peripheral sedimentary rock-hosted skarn-hydrothermal deposits and epithermal deposits that lies inside fault fracture zone from which rock bodies are far away.
