摘要
通过东天山地区地球化学勘查中某些方法的试验,研究了一套适宜于戈壁荒漠景观中地球化学勘查的工作方法。(1)查明了盛行风对岩屑异常特征的影响程度;(2)推荐消除风成沙影响的合理采样粒级;(3)利用水溶态铜、金异常指示被运积物掩盖的铜、金矿体;(4)明确了荒漠区盐磐层不会阻碍在残积物覆盖区发现矿致岩屑异常和在运积物覆盖区发现后生晕。
On the basis of method test on some copper/gold mineral deposits in East Tianshan region, the article tackled some technical issues and worked out some working methods suitable for mineral geochemical prospecting in the desert landscape. The major points are shown as follows. （1） It has confirmed the influence of prevailing wind on debris anomalies. （2） It has recommended suitable sampling grain size possible to get rid of eolian sand. （3） it has verified that water extracted copper/gold anomalies can indicate copper/gold ore bodies buried by transported overburden. （4） It has confirmed that salt bed in desert is not a barrier to the finding of debris anomalies related to mineralization in eluvium overburden and to the finding of epigenetic haloes in transported overburden.
