新疆乌什县卡恰金矿原生晕地球化学异常特征分析

卡恰金矿床属于与火山热液有关的蚀变岩型金矿床,金矿体多呈规模不大的脉状、透镜状、分支脉状等形态分布于构造蚀变带中。文章通过对矿区进行系统的坑道和地表原生晕地球化学取样,分析研究了主要元素的组合、异常特征;对比坑道和地表元素地球化学主要指标变化特征,推测了元素向深部变化的趋势,为矿区深部及外围找矿工作提供了参考依据。

Analysis on characteristics of geochemical anomly in the primary halo of Kaqia gold deposit in Wushi county, Xinjiang

Kaqia gold deposit is a altered rock type deposit related to volcanic hydrothermal fluid. Ore bodies generally occur as vein, lens and dendroid vein in cataclastic alteration zone. Geochemical samples are collected systematically from the primary halo in tunnels and at surface and study are made on combination of elements and anomly characteristics. Characteristics of major geochemical index variation for element in tunnel and at surface are compared. Variation tendency of elements are inferred to depth providing evidence for further ore prospecting in surroundings and to depth of the deposit.
