摘要
卡而却卡北锌多金属矿床位于东昆仑祁漫塔格成矿带西段,成矿时代为中—晚三叠世,为近两年发现的新型矿床(点)。研究区内出露的古元古界金水口岩群;印支期一系列中酸性岩浆岩以及区内发育的一条北西向压扭性断裂构成主要控矿因素。通过研究,区内沿构造方向形成以隐爆角砾岩型铅锌铜矿化为主体,同时伴随矽卡岩型铅锌矿化及低温热液型铜铅锌矿化的岩浆热液成矿系列。隐爆角砾岩中含矿角砾的发现也为研究区内深部寻找斑岩型矿床提供了依据。
Kaerquka zinc polymetallic Deposit is located in western Qimantage mountains. It was found a new type of ore deposits （points） in the past two years. along Jinshuikou rock group of the Paleo-proterozic, including ndo-chinese epoch metallogenic belt in East Kunlun The main ore-controlling factors are intermediate-acid granitoids, a NW trending compression and Compresso-shearing fault. The author thinks that it has formed the cryptoexplosion breccia type Pb-Zn-Cu deposit which was the main body of Magmatic hydrothermal metallogenic stoics. At the same time, it has been formed in the skarn type deposits and low temperature hydrothermal type deposit. It can provide a basis for the deep looking for porphyry deposits which has been found in the mineralized breccia of cryptoexplosive breccias.
