    GEOPHYSICAL AND GEOCHEMICAL CHARACTERISTICS AND GOLD-SILVER POLYMETALLIC METALLOGENIC CONDITIONS IN AHADAWA AREA, QINGHAI PROVINCE

    • 摘要: 研究区位于柴达木盆地东南缘, 大地构造隶属于柴达木盆地北缘蛇绿混杂岩带. 通过对区内成矿地质背景、地球物理和地球化学特征进行综合研究, 并与邻区赛坝沟金矿对比分析, 认为研究区具有优越的成矿地质背景和良好的物化探异常, 与赛坝沟金矿具有相似成矿背景. 区内寻找构造蚀变岩型金多金属矿和热液充填矿床的成矿条件极为有利.

       

      Abstract: The study area is located in the southeast margin of Qaidam Basin, tectonically belonging to the northern Qaidam ophiolite melange zone. Based on the comprehensive study of metallogenic geological setting, geophysical and geochemical characteristics, and comparison with the neighboring Saibagou gold deposit, it is concluded that the study area has advantaged metallogenic background and well geophysical and geochemical anomalies, with similar metallogenic background to Saibagou gold deposit. There are favorable metallogenic conditions for tectonic altered rock type of gold polymetallic deposit and hydrothermal filling deposit prospecting in the area.
