新疆阿舍勒铜矿的发现与电法勘探

ELECTRICAL PROSPECTING IN DISCOVERY OF COPPER DEPOSIT, ASHELE, XINJIANG

新疆阿舍勒铜矿是一个隐伏的与火山成因有关的大型块状硫化矿床。它的发现是根据地质调查提出的有色金属找矿靶区。通过自然电场法和激发极化法等综合电法勘探发现电异常,经钻探验证,采用地质、物探、钻探、科研综合普查方法密切配合取得的成果。其中电法勘探起到了导向作用。在发现这一隐伏块状硫化矿床的基础上,对矿区及外围进行了瞬变电磁法等电法勘探的新方法、新技术试验研究工作。根据瞬变电磁法获得的成果,结合自然电场法,激发极化法和地质、化探资料进行综合解释推断,提供了可能存在新的隐伏矿床的信息,指出了进一步普查找矿方向,对扩大该区远景具重要意义。

Coupled with geological and geophysical prospectings, drilling and detailed studies, the comprehensive electrical prospectings including natural electric field and polarization were conducted on the prospecting target of nonferrous metal, and took a leading role in the discovery of Ashele copper deposit of Xinjiang, a large - sized blind massive sulphide deposit of volcanic origin. A new method of transient electromagnetization was also applied in the study of this area and lts surroundings. The comprehensive interpretations supply new imformation for seeking more blind deposits orientally, thus making an important significance on the prospect study.
