甘肃照壁山地区地球化学特征及找矿潜力分析

Analysis of geochemical characteristics and prospecting potential in Zhaobi mountain area of Gansu Province

本文分析了甘肃照壁山地区1/5万水系沉积物测量成果,重新圈定了研究区的综合异常,研究结果表明,照壁山地区具有Au-Ag-Sb-Hg和Au-Ag综合异常,前者各元素套合好、异常浓集中心突出,分带性好,具有较好的找矿潜力,是寻找热液型Au、Ag矿床的有利部位;后者异常分带性差,异常浓集中心不突出,异常面积小,可能是构造运动产生的石英脉引起的异常,不具有找矿意义。

This paper analyzes the results of 1/50,000 water system sediment measurement in Zhaobi mountain area of Gansu province,and re-identified the comprehensive anomaly of the study area,and the results show that there are Au-Ag-Sb-Hg and Au-Ag comprehensive anomalies in the Bishan area,the former elements are fitted well,The abnormal concentration center is prominent,the stripe is good,has the good prospecting potential,is the search for the hydrothermal type Au,the Ag deposit favorable part,the latter the abnormal stripe is poor,the abnormal concentrated concentration heart is not prominent,the abnormal area is small,may be the quartz veins produced by the tectonic movement caused by the abnormality,does not have the prospecting significance.
