广东省麻布岗地区1∶5万水系沉积物测量异常评价及找矿方向

摘要

通过对广东省麻布岗地区1∶5万水系沉积物测量数据进行R型因子分析，划分元素组合，圈定出了13个综合异常。从综合异常特征方面分析，确定了7个找矿远景区。在对成矿地质条件、化探异常特征及开展矿产检查工作的基础上，优选出4号和11号综合异常区为找矿靶区。%Through R-type factor analysis of 1 ∶ 50 000 stream sediment survey in Mabugang area, Guangdong Province,13 composite anomalies were delineated. Based on characteristics of composite anomalies and exploration evaluation, the authors confirmed 7 pro-spective areas. According to the geological conditions for mineralization as well as characteristics of anomalies during geochemcial explo-ration and mineral exploration, No. 4 and No. 11composite anomalies are considered to be target areas.
