The application of debris and soil geochemical measurement methods to the Shaquanzi Cu-Ni deposit, Xinjiang

Publish Date: 10 April 2015

摘要: 在新疆沙泉子铜镍矿上方开展岩屑测量和土壤微细粒全量测量的试验工作,试验结果显示,两种方法圈定的成矿元素地球化学异常具有Cu?Ni?Cr?Co多元素异常组合的特征,且异常分布范围与深部矿体较为一致,表明岩屑测量和土壤微细粒全量测量可以有效地指示铜镍矿体,可作为该区寻找铜镍矿的有效手段。相比较而言,土壤微细粒全量测量效果更好,表现在元素含量更高,异常强度更强,由此便能强化微弱异常,有利于发现和识别弱的矿化信息。

Abstract: Pilot comparative study of detritus and soil geochemical surveys was conducted over the Shaquanzi Cu?Ni deposit of Xinjiang. The results show that there are Cu?Ni?Cr?Co geochemical anomalies delineated by these two methods, and the anomalies are located right over the known orebodies, indicating that the two methods can be used to effectively locate reliable prospecting targets in Gobi desert terrain. A comparison shows that fine?grained soil can yield relatively better results in that it shows higher element concentrations and intensive anomalies over the deposit, which could help identify weak anomalies caused by mineralization in such landscape.
