青海省都兰县郭勒纸铜矿区地质特征及找矿前景浅析

Geological Characteristics and Prospecting Potentiality of Guolezhi Copper Deposit in Dulan County of Qinghai Province

摘要:

工作区位于东昆仑山脉中段，布尔汗布达山南坡。区域上断裂构造较为发育，岩浆活动频繁，岩浆热液以及岩浆期后热液活动强烈，为成矿元素的进一步活化、运移、富集创造了条件。该文对区内的成矿地质背景、矿床地质特征，矿石特征、矿床成因及控矿因素进行研究分析，认为该矿床有着较好的找矿前景。同时也确定地层标志、构造标志、蚀变标志为其找矿标志，以指导后续普查工作的有效进行。

Abstract:

The working area is located in the middle part of Dongkunlun，and the southern slope of Burhan Budai mountains. Regional fractures, magmatite activity, and magmatic hydrothermal activities are very strong. It provides the conditions for further activation, migration and enrichment of oreforming elements. In this paper, metallogenic geological background, geological characteristics of the deposit, ore characteristics，origin of the deposit and ore controlling factors have been analyzed. It is considered that the deposit has good ore prospects. At the same time，stratigraphic signs, structure signs, alteration signs have been determined as ore prospecting signs in order to effectively guide survey work in the future.
