老君山地区水系沉积物测量地球化学特征及钨矿找矿应用
|
摘要
在1∶5万水系沉积物测量的基础上,对云南老君山地区的地球化学特征进行了初步分析。对元素分布特征、单元素异常特征、元素相关性分析、异常元素组合特征进行了研究。研究发现:W、Sn、Pb、Zn为区内具有一定潜力的找矿指标,划分了5个成矿远景区,并以区内钨矿找矿实例,初步总结了老君山地区寻找钨矿需要注意的问题。
This preliminary study of geochemical features in Laojunshan area was perliminarily based on 1∶ 50,000 stream sediment survey. It is about element distribution characteristics,including element anomalies,element correlation and element anomaly assemblage. The result shows that the study area might be a prospective area for W,Sn,Pb and Zn. Five metallogenetic prospective provinces are optioned synthetically. Finally,some matters will be in need of attention to tungsten prospecting,as is presented.
