| 摘 要： | 建立了隐伏区土壤地球化学测量中元素活动态值异常下限（T）的统计计算方法,定义了点对比值（Ci=xi/T）,制定了Ci〉1为异常值的统计识别模式。应用新建立的方法,在森林及土壤覆盖景观的金厂矿区进行了实验和应用。由已知区的实验结果表明,土壤中活动态金异常值分布与已知金矿带完全对应,并且在远景区所圈定的金异常区与地质认识相符,部份异常已经钻探工程验证。

| Abstract: | The calculation method of mobile elements anomaly limit (T) in geochemical soil samples from concealed deposit area was developed. The contrast value( Ci = xi/T) was defined and a statistical identifying mode of the anomaly was established ( singular date was picked out when Ci > 1 ). The method was applied in Jinchang gold deposit area which laid in the forest and black-land zone. The test result showed the mobile in Au anomaly values inosculated ideally with the Au deposits of known. Au anomaly scopes obt... |
