青海昆仑山口—两湖地区金矿成矿模式
Gold Deposit Metallogenic Model in Kunlun Mountain-Two Lakes Area, Qinghai Province, China

摘要: 昆仑山口—两湖地区成矿条件优越，是青海省金矿的生产地。笔者通过对大场金矿的地质背景、矿体特征、成矿时代、成矿期次、成因类型和控矿因素等多方面进行总结和研究，认为昆仑山口—两湖地区金锑矿床主要产于早—中三叠世昌马河组砂板岩中、受控于甘德-玛多断裂带，指出Au、As、Sb元素在动荡环境中极易活化富集成矿，且在多组断裂交汇处最易富集，进而总结该区金锑矿的成矿规律、分析成矿时空演化过程、建立成矿模式，为今后找矿提供指示意义。Abstract: Kunlun Mountain-two lakes area has superior metallogenic condition, and is the main gold production area. According to the study of geological setting, ore characters, mineralization epoch, metallogenicperiods, genetic types and ore controlling factors of typical deposit, we know thatthe gold mine of Kunlun Mountain-two lakes area was produced in Changmahe Fm. Early-Middle Triassic, and controlled by Gande-Madu fault zone. This paper assures Au, As and Sb are easy activation mineralization in the turbulent environment, and easy enriched in the junction of several faults. On this basis, we summary regional metallogenic regularity and established metallogenic model, and instructive significance for future prospecting.
