青海阿达滩沟脑铜多金属矿床地质特征、控矿因素及找矿方向

GEOLOGY, ORE-CONTROLLING FACTORS AND PROSPECTING DIRECTION OF THE ADATANGOUNAO COPPER POLYMETALLIC DEPOSIT IN QINGHAI PROVINCE

摘要: 阿达滩沟脑铜多金属矿床位于祁漫塔格-都兰华力西期铁、钴、铜、铅、锌、锡、硅灰石Ⅲ级成矿带.矿区内发现5条铜铅锌矿化带，共包含7条矿（化）体，为铜矿体及铅锌矿体.矿体主要受断裂构造的控制，具有褐铁矿化、黄铁矿化、绢云母化、硅化、碳酸盐化等蚀变.通过对矿床地质特征的分析研究，探讨了成矿控制因素及其对该区域找矿勘查的意义.

Abstract: The Adatangounao Cu polymetallic deposit is located in the Variscan Qimantage-Dulan Fe-Co-Cu-Pb-Zn-Sn-wollastonite Grade-Ⅲ metallogenic belt. Five Cu-Pb-Zn mineralized belts are discovered, including seven Cu and Pb-Zn orebodies. Mainly controlled by fault structures, the orebodies are characterized by various alterations such as limonitization, pyritization, sericitization, silicification, and carbonatization. The ore-controlling factors and their prospecting significant for the area are discussed by analyzing the geological characteristics of the deposit.
