VLF －EM和 EH4在浅覆盖区萤石矿床勘查中的应用--以林西水头萤石矿区为例
Exploration of fluorite deposit by the combination of VLF-EM and EH4 on shallow-covered area-A case study of the Shuitou deposit
摘要
Abstract
To explore the effect of VLF-EM and EH4 for semi-concealed fluorite deposits in the grassland, Shuitou fluorite deposit in Linxi area is selected as the case study.Through the raw data processed and interpre-ted on the basis of the geological fact,the results show that VLF-EMcan rapidly evaluate the shallow (less than 60 m)distribution features of the structures with low resistivity to ore or mineralized bodies.The survey with EH4 can reveal the spread distribution of structural belts in deep space(almost reach 1 000 m).Based on the geological or geochemistry data,the effective combination of VLF-EM and EH4 can be efficient to forecast the location of the buried ore bodies.It has many advantages over traditional models.(1 )The two methods,from shallow to deep,can be compared and complemented one another.(2)It can provide a scientific basis for fur-ther exploration of fluorite deposits.(3)It is one way of exploring the concealed and semi-concealed deposits.关键词
