青海省祁漫塔格地区卡而却卡矿床地质特征及找矿方向

Geological Characteristics and Prospecting Direction of Ka'erqueka Deposit in Qimantage Area,Qinghai Province

卡而却卡矿区位于青海东昆仑祁漫塔格成矿带,矿床多金属规模已达大型。然而近年随着工作程度的不断深入,矿区找矿难度也逐渐增大。综述了卡而却卡矿床地质特征,总结了近两年矿区在金矿找矿当中的新突破,并指出V,VI,XI矿带是今后金多金属矿找矿的重点地段;同时也对该矿床的成因进行了分析,认为该矿床成因具有斑岩型(铜钼矿)—矽卡岩型(铜铅锌)—热液型(金铅矿)成矿系列特征。

The Ka ＇erqueka deposit is located in the qimantagong metallogenic belt in eastern kunlun of Qinghai province,the polymetallic deposits have reached a large scale.However,with the deepening work in recent years,the difficulty of prospecting in mining areas is also increasing.In this paper,the geological characteristics of callika deposit are summarized,and the new breakthrough of mining area in the recent two years is summarized.At the same time,the genesis of the deposit is analyzed,and it is concluded that the genesis of the deposit has the characteristics of porphyry type（copper molybdenum ore）-skarn type（copper,lead and zinc）-hydrothermal type（gold lead ore） series.
