柴周缘晶质石墨矿成矿地质特征及找矿潜力分析

Metallogenic characteristics and prospecting potential analysis of the crystalline graphite ores in surrounding area of Qaidam Basin

为加快柴周缘地区石墨矿勘查进程,在系统收集晶质石墨矿资料的基础上,通过野外调研及典型石墨矿床的综合研究,对柴周缘晶质石墨矿的成矿地质特征及找矿潜力进行了分析,总结了石墨矿的成矿规律、地质特征、成因类型及找矿标志,开展了石墨矿床成矿地质条件研究和找矿靶区预测,确定了两个成矿远景区。柴周缘广泛发育的古老变质岩系中晶质石墨矿找矿潜力巨大。

To speed up the exploration process of graphite deposit in surrounding areas of the Qaidam Basin, on the basis of gathering the crystalline graphite deposit documents,an exploratory survey and comprehensive study of the typical deposits was conducted. The metallogenic geological charac-teristics and geological characteristics were analyzed. The metallogenic regularity, mineralization characteristics, genetic type and prospecting criteria of graphite deposit were summarized. The geo-logical characters and ore - forming conditions of graphite deposit were studied and the prediction of prospecting targets was carried out,and two metallogenic prospecting areas were identified. The crystalline graphite ore prospecting potential in the extensive developed ancient metamorphic rocks is great at surrounding areas of the Qaidam Basin.
