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。
卡爾卻卡銅多金屬礦床位于東昆崙祁漫塔格成礦帶,為該區近年來髮現的最重要礦床之一。本文通過對卡爾卻卡銅多金屬礦床地質特徵及同位素地毬化學特徵的詳細剖析,併結閤其成巖成礦時代,認為卡爾卻卡銅礦為廣義斑巖型礦床,即以侵入體為中心的斑巖型-矽卡巖型礦床,外圍賦存于沉積巖內的矽卡巖-熱液型礦床和遠離巖體的斷層破碎帶內的淺成低溫熱液礦床組成的斑巖礦床成礦繫。

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 min-eralogenetic age suggests that Kaerqueka copper deposit is a generalized porphyry deposit,namely a porphyry metallogenic system which consists of intrusive body-centered porphyry-skarn type deposits,peripheral sedi-mentary rock-hosted skarn-hydrothermal deposits and epithermal deposits that lies inside fault fracture zone from which rock bodies are far away.
