摘　　要：虎头崖多金属矿是青海省祁漫塔格成矿带重要的多金属矿床之一,区域内矿产丰富,矿种多样,主要以铁、铜、铅、锌的多金属为主。本文结合前人研究成果和项目组对虎头崖多金属矿床的现场调查和室内多元信息的综合分析,从虎头崖矿区地层、地质构造、岩浆活动等方面探讨了该矿床的成矿地质条件;重点分析了该矿床的矿体形态产状特征、矿石组成,矿床成因、矿床特征,并分析了成矿作用的分期活动过程和成矿机制;通过综合分析,本文认为可从现有Ⅰ、Ⅱ矿带由北西向南东的侧列方向及平行F1、F2、F3等断裂带追索寻找深部隐伏盲矿体,并可根据物探异常找隐伏岩体,根据化探Cu、Pb、Zn组合异常找隐伏矿化破碎带,我们已探明虎头崖的金属矿产储量在原有基础上有了很大的提高,取得了重大找矿突破。The Hutouya polymetallic deposit is one of the important deposits in the Qimantage polymetallic metallogenetic belt in Qinghai Province,which is dominated by iron,copper,lead,and zinc.Based on previous research and our field investigation and multiple-information analysis to this deposit,we describe the ore-forming geological conditions from strata,geological structure and magmatic activity in the Hutouya region,focusing on the occurrence features of ore bodies,ore composition,deposit genesis and deposit characteristics.We analyze the process of activities of each periods and ore-forming mechanism.We suggest that blind ore bodies at depth should be searched from northwest to southeast of the existing ore belts Ⅰand II as well as in the direction parallel to the faults F1,F2,and F3.And concealed rock bodies should be detected according to geophysical anomalies,and geochemical anomalies of Cu,Pb,and Zn can be used as marks of buried mineralized fracture zones.
