阿拉善左旗达拉金夏尔地区地球化学特征研究

Study on Geochemical Characteristics of Dalajinshaer Area in Alxa Left Banner

为了查明阿拉善左旗达拉金夏尔地区金及多金属赋存状况,笔者单位在该区开展了1∶5万路线地质调查、1∶2.5万土壤地球化学测量,1∶1万地球化学剖面测量等工作,大致查明了该区的地球化学特征,笔者通过分析地球化学异常特征和组合异常,圈定了异常找矿靶区2处,为下步在该区开展工作奠定了基础。

In order to find out the occurrence of gold and polymetallic in the Dalajinshaer area of Alxa Left Banner,the author carried out a 1 ∶ 50000 route Geological survey,a 1 ∶ 25000 soil geochemical survey,a 1 ∶ 10000 geochemical profile survey and other work in the area,and roughly identified the Terraforming characteristics of the area.The author delineated two abnormal ore prospecting targets by analyzing the characteristics of geochemical anomalies and combined anomalies,This has laid the foundation for further work in the area.
