摘要: 1982至1983年在云南腾冲一已知水热区及其毗邻约 60km2 范围内采集了131个土壤样品。样品分析结果表明锂和铷的异常能圈定两个已知水热区,且与若干已知热田地球化学指示元素的异常相当一致,从而进一步肯定了这一地区的开发前景。与此同时,对区内水样中的钠钾含量也进行了测定并做出解译。锂铷和已知地球化学指标之间的相关分析表明它们之间确存有某种内在联系,同时可看出盐湖与古地热系统之间的一些联系。最后得出结论:土壤中的锂铷可作为圈定热田的地球化学指标;地热系统不仅能作为能源资源而且也应视作矿产资源。

Abstract: Li and Rb values in 131 soil samples collected from 1982 to 1983 within an area of 60 km2 in the known hydrothermal active areas and their vicinity in Tengchong, Yunnan Province have been determined. The Li and Rb anomali es delineate two known hydrothermal active areas, rather consistent with the anomalies of the known geochemical indicator elements, including Hg As Sb Bi and B, and further confirm their prospects. At the same time Na and K values in hot waters of this field have also been determined and interpreted.Correlation analyses of Li, Rb and the known geochemical indicators are made. There exists a certain linkage between fossil geothermal systems and salt lakes. It is concluded that the presence of Li and Rb in soil could well be used to delineate geothermal fields, and geothermal systems could be exploited not only as energy resources, but also as mineral resources.
