| 中文摘要: |
| 青海省托勒南山附近铁、铜、金等矿产资源丰富,且南部存在多处航磁异常,找矿潜力较大。文章采用地质、物探等多种技术手段对托勒南山附近大白石头沟地区磁异常进行研究,不仅分析了该区主要岩石(地层)的磁性特征及该区磁场特征,而且利用多种技术手段对引起磁异常的钛磁铁矿特征进行了研究。分析归纳了该区钛磁铁矿化带的分布特征及成因,为该区矿产勘查工作提供了依据。 |
| 英文摘要: |
| There are many minerals resources such as iron, copper, gold and other minerals in the area near Tuole Nanshan in Qinghai, in south area of where there are many aeromagnetic anomalies with a large potential for prospecting. In this paper, the magnetic anomalies in the Great White Stone Ditch area are studied by means of geological, geophysical and geochemical exploration technologies. It not only analyzed the magnetic characteristics of the main rock (stratum) and the characteristics of the magnetic field in this area, and also used a variety of technical means to study the characteristics of titanium magnetite which caused the magnetic anomaly. The distribution characteristics and genesis of the magnetite mineralization zone in this area were also analyzed and summarized, which would provide a basis for mineral exploration work in this area. |
