The Experimental Study of Deep-Penetrating Geochemical Methods in Jiajika Rare Metal Deposits in Western Sichuan

An experimental research was conducted on the No. X03 super-large concealed lithium ore body in Jiajika rare metal orefield to explore the deep-penetrating geochemical method for searching the concealed ore bodies in this area. This article describes the results obtained by soil extraction method and geogas survey. Notable anomalies of water-extractable Li, Rb, Cs in the soil, and Li, Rb, Cs in geogas have been found above the buried orebody. So, both of the methods have the potential to be used for the concealed deposits detection in Jiajika area. Correlation analysis of water-extractable Li, Rb or Cs in the soil and these rare metals in the geogas indicates that probably ore-forming elements are transferred to the earth surface by geogas.
