青海都兰县按纳格地区金矿地质特征与成矿机理研究

摘要

研究区位于塔里木-柴达木板块柴达木板段南缘昆仑前锋弧东段,东部为鄂拉山晚古生代-三叠纪火山-岩浆弧弧前增生锲,与金属成矿作用关系最为密切的是早古生代和晚古生代-早中生代两个构造-岩浆旋回,产出的金矿床具有造山带金矿特征.对研究区地质特征进行详细分析,进而对矿床成因及找矿标志进行深入研究,对以后的工作具有十分重要的指导意义.%The census area is located in eastern section of Kunlun striker arc in southern margin of Qaidam plate of Tarim-Qaidam plate.Eastern part is Late Paleozoic-Triassic volcanic-magmatic arc in pre-growth.Closely related to early Paleozoic and Late Paleozoic-Early Mesozoic of two tectonic-magmatic cycles, the output of gold deposits are with orogenic features.In this paper, we have studied the geological characteristics in detail, including the ore genesis and prospecting signs, which is of great significance to the future work.
