    青海赛什腾地区石英脉型金矿特征及找矿前景分析

    Characteristics and Prospecting Potential of Quartz Vein-Type Gold Deposits in Saishiteng Area, Qinghai Province

    • 摘要: 赛什腾金矿位于青海省海西州冷湖镇,是复合内生石英脉型金矿床。赛什腾金矿赋存于加里东期石英脉及其接触带和剪切蚀变带中,具有石英脉集中发育、矿化集中、金含量高、水系异常套合好的特征。处在同一构造单元(柴达木北缘结合带)和同一成矿亚带(赛什腾山-阿尔茨托山同-成矿亚带)中的滩涧山蚀变岩型金矿、野骆驼泉构造蚀变岩型-石英脉型金矿床、红柳沟石英脉型金矿床和赛什腾复合内生石英脉型金矿在不同成矿时代、不同位置形成不同类型的金矿床。通过对比研究该地区金矿床的特征,对总结成矿规律和综合找矿具有重要的现实指导意义。

       

      Abstract: Saishiteng gold deposit, located in Leihu Town of Qinghai Province, is a composite endogenetic quartz vein-type gold deposit.Mineralization occurs in Caledonian quartz veins and the contact and shear alteration zones, characterized by intensively developed quartz veins, concentrated mineralization, high gold content and good nesting of drainage anomalous. Though gold deposits of Tanjianshan altered-type, Yeluotuoquan tectonic altered-type, Hongliugou quartz vein-type and Saishiteng composite endogenetic quartz vein-type were in the same tectonic unit (Northern margin Junction of the Qaidam basin) and the same metallogenic sub-belt (the Saishiteng-Alto Mountains metallogenic sub-belt), different types of gold deposits were formed in different ore-forming ages and positions.The comparison of different gold deposits is of practical guiding significance for metallogenic regularities and further comprehensive prospecting.
