综合找矿方法在西藏象日锑矿床的应用

西藏措美县象日锑矿是近年来通过区域地质调查新发现的锑矿床,其矿化带受断裂构造控制。文章在简要介绍区域成矿地质背景后,通过综合分析矿区的地质特征、1∶5万水系沉积物地球化学特征、1:1万土壤地球化学特征、物探音频大地电磁测深(AMT)和1:1万激电中梯剖面特征,结合遥感地质特征,取得了较好的应用效果,为该区进一步找矿指明了方向,作者结合对该区地物化遥综合找矿勘查应用,总结出了适用于高原山区浅覆盖-隐伏矿床(体)的勘查流程。

Application of integrated prospecting methods on Xiangri stibnite deposit,Tibet

Xiangri stibnite deposit in Cuomei County of Tibet, newly discovered by regional geological survey in recent years, is controlled by fault structure. This paper briefly introduces the regional metallogenic geological background and comprehensively analyzes the geological characteristics, 1:50000 stream sediment geochemical characteristics, 1:10000 soil geochemical characteristics and geophysical characteristics of audio magnetotelluric sounding (AMT) and 1:10000 induced polarization intermediate gradient (IP) survey profile of the property, these characteristics along with remote sensing characteristics have good application effect on prospecting, and point out the direction for further prospecting work in the area. Therefore, a set of prospecting process that available for shallow-covered-concealed deposits in plateau mountainous areas has been summarized based on the comprehensive prospecting application of geological, geophysical, geochemical and remote sensing prospecting methods.
