摘要: 以川西甲基卡稀有金属矿区X03号超大型隐伏锂矿体为研究对象，同时开展土壤金属活动态测量和地气测量，以探索在该区寻找隐伏矿体的深穿透地球化学方法。结果表明，去离子水提取土壤金属活动态和地气测量均能在隐伏矿体上方发现Li、Rb、Cs等成矿元素地球化学异常，且异常与已知隐伏矿体的位置对应良好，能有效指示隐伏矿体，可用于在甲基卡稀有金属矿区寻找隐伏矿体。去离子水提取的活动金属态及地气中Li、Rb、Cs等元素含量的相关性表明，地气对隐伏矿体成矿元素的运移作用是土壤中金属活动态异常形成的主要原因。
Abstract: 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.
