摘要:
黑海北金矿床位于东昆仑南部（坳褶带/增生楔）Cu-Co-Au成矿亚带内。为确定该矿床地质特征，为探矿增储提供理论指导，通过开展大比例尺地质填图、槽探和钻探工程，查明了矿区及矿床地质特征，探讨了控矿因素、找矿标志和找矿前景。矿区矿体严格受构造控制，尤其以北西西构造为主要控矿因素；已发现矿（化）体均赋存于二长花岗岩内，印支期—燕山期岩浆岩为重要的控矿因素；矿化露头、构造破碎带、化探异常和围岩蚀变为重要找矿标志。该矿床成因类型为与断裂关系密切的岩浆热液型。综合分析认为，矿区成矿地质背景良好、找矿成果显著、深部成矿前景良好，加大勘查力度有望取得重大找矿突破。

Abstract:
Heihaibei Gold Deposit is located in Cu-Co-Au metallogenic subbelt in the south of East Kunlun(depression fold belt/accretionary wedge).In order to find out the geological characteristics to provide theoretical guidance for the exploration,the study carried out large-scale geological mapping,trough exploration and drilling projects in the area,investigated the geological characteristics of the district and the deposit,and discussed the ore-controlling factors,prospecting markers and prospecting prospects.The ore bodies in the district were strictly controlled by the structures,especially the NW structures,were the main ore-controlling factors;the ore(mineralization) bodies discovered occurred in monzogranites,and the Indochina-Yanshanian magmatic rocks were the important ore-controlling factors;mineralization outcrops,structural fracture zones,geochemical anomalies and wall rock alterations were all important prospecting markers.The genetic type of the deposit was a magmatic hydrothermal gold deposit closely related to fault structures.According to comprehensive analysis,it was expected to make a great breakthrough in prospecting by increasing exploration efforts because of the good metallogenic geological background,remarkable prospecting results,good deep metallogenic prospects.
