广西藤县古奔地区化探异常特征和金矿找矿前景预测

Characteristics of Geochemical Anomalies and Prediction of Gold Prospecting Prospects in the Guben Area of Tengxian County,Guangxi

广西藤县古奔地区位于大瑶山成矿带中东部,区域上成矿地质背景良好,金矿点分布较多,已发现和进行开采的金矿床(点)多为中、小型,数量达30多处,矿床类型主要为石英脉型和破碎带蚀变岩。基于前人基础地质工作和矿床研究,与区域上典型金矿的地质特征及矿床成因进行对比,结合本次化探异常特征进行了研究,分析古奔地区已发现未进行开采金矿体的地质特征和成矿预测,提出了该区寻找金矿的找矿前景。

Guben area,Tengxian County,Guangxi is located in the middle east of Dayao Mountains metallogenic belt.The regional metallogenic geological background is good,and there are many gold spots distributed.Most of the gold deposits(spots)that have been discovered and mined are medium and small,with more than 30 in number.The types of deposits are mainly quartz vein type and altered rocks in the broken zone.Based on previous geological work and ore deposit research,a comparison was made with the geological characteristics and genesis of typical gold deposits in the region.Combined with the abnormal characteristics of this geochemical exploration,the geological characteristics and mineralization prediction of discovered and unexplored gold deposits in the Guben area were analyzed,and the prospecting prospects for gold deposits in the area were proposed.
