摘要
通过开展1∶5万水系沉积物测量工作,对甘肃肃南红石嘴中梁—白泉门地区的地球化学参数进行计算和分析,结合各地质单元地球化学特征、元素相关性和组合特征、综合异常特征,认为调查区应以Cu、Ag、Sb、Au等矿种重点来开展,并圈定综合异常10处。其中与中酸性侵入岩有关的综合异常3处,与阴沟群有关的综合异常6处,与阴沟群和基性—超基性杂岩有关的综合异常1处。本次工作认为AS6、AS7、AS10综合异常找矿前景良好,并开展了大比例尺的查证工作,取得了一定的找矿成果,为该区下一步找矿工作指明了方向。
        Based on the 1 ∶ 50000 water system sediment, the geochemical parameters of Hongshizuizhongliang-Baiquanmen area of Gansu province were calculated and analyzed, Combined with the geochemical characteristics, element correlation, combination characteristics and comprehensive anomaly characteristics of each geological unit, It is believed that the investigation area should be focused on Cu, Ag, Sb, Au and other minerals, and delineate 10 comprehensive anomalies.There are 3 comprehensive anomalies related to medium-acidic intrusive rocks, 6 comprehensive anomalies related to the formation exposure of the yingou group, and1 comprehensive anomaly related to the yingou group and the basic-ultrabasic complex. This work believes that the comprehensive anomaly prospecting of AS6, AS7 and AS10 has a good prospect, And carried out a large-scale verification work, and achieved certain prospecting results, pointing out the direction for the next prospecting work in this area.
