青海省东昆仑大格勒沟地区铜多金属矿地质特征及矿床成因

Copper polymetallic deposit geological characteristics and genesis of Dagelegou area in the eastern Kunlun,Qinghai

为了研究青海省东昆仑大格勒沟地区铜多金属矿成因,对该矿区的控矿因素、矿床成因及找矿前景进行了综合分析。结果表明:青海省东昆仑大格勒沟地区铜多金属矿成矿条件优越,成矿类型主要分为构造蚀变岩型金、铜、铅多金属矿和岩浆熔离型镍(伴生钴、铁)矿,成矿时期为印支早期。该研究成果为区域上铜金多金属矿的系统研究及矿区的下一步找矿工作提供了较为可靠的地质依据。

In order to investigate the copper polymetallic ore genesis of the Dagelegou area in the eastern Kunlun, Qinghai, the regional geology and mine geology and ore bodies characteristics, ore characteristics of the Dagelegou area, the ore controlling factors, ore genesis and prospecting poten-tial of the mining area are analyzed comprehensively. The results show that： copper polymetallic ore metallogenic conditions are good at Dagelegou area, East Kunlun, Qinghai. The metallogenic types are mainly tectonic altered gold, copper, lead and polymetallic deposits rock type, and magmatic li-quation type nickel （ cobalt and iron） ore. The mineralization period is the early Indosinian. The re-sults provide a reliable geological basis for the systematic study of the copper gold polymetallic de-posits and the next step of prospecting in the mining area.
