青海格尔木红石山地区水系沉积物测量异常特征及优选找矿靶区

摘要

通过对红石山地区1∶2.5万水系沉积物资料处理,圈定了W、Sn、Bi、Au、As、Sb、Cu、Pb、Zn等异常,揭示了区内异常的分布特征,评价异常的找矿意义,划分了元素组合.结合地质成矿背景,依据化探综合异常及元素组合特征,确定钨、金、铜多金属的3个找矿远景区,其中优选1号综合异常为最佳钨、金找矿靶区.%Rased on data processing of 1: 25 000 stream sediment survey in Hongshishan area, the authors delineated anomalies of such elements as W, Sn, Bi, Au, As, Sb, Cu, Ph and Zn, revealed distribution characteristics of anomalies in this area, evaluated prospecting significance of the anomalies, and determined element associations. According to characteristics of composite anomalies and element associations in combination with ore-forming geological setting, three ore-search prospective areas of W, Au and Cu were delineated, of which the optimized No. 1 composite anomaly seems to be the best ore-prospecting target area for W and Au.
