应用选择性离子电极快速分析技术的发展,使氟的地球化学测量成为温带和寒带地区的一种有用的勘查工具。本文以昌迪东里萤石矿区(21°05′:80°37′)残积土中氟矿化为例研究了用F作为热带、湿热带地区萤石矿术的指标问题。该矿床由含少量Pb、Zn硫化物矿化的石英-萤石脉组成,它赋存于栋加尔加尔花岗岩(前寒武纪)的陡倾斜断层带中。样品中氟化物总量用一种经改进了的菲克林直流电位法(Di-ect Potentiometry)测定,其含量范围为50-4000ppm。测量结果表明,在热带地区类似的地形条件下,氟可以作为萤石矿床的一种直接指标。
The rapid development of selective ion-selective electrode technology has made fluorochemical geochemical measurements a useful exploration tool in temperate and boreal regions. In this paper, the fluorite mineralization in the residual soil of Chandidoruli fluorite mine (21 ° 05 ’: 80 ° 37’) was studied as an index to use F as an indicator of fluorite mineralization in tropical and wet tropical regions. The deposit consists of a quartz-fluorite veins mineralized with a small amount of Pb and Zn sulphides. It occurs in the steeply sloping belt of the Upgallgar granite (Precambrian). The total amount of fluoride in the sample was determined using a modified Di-ect Potentiometry in the range of 50-4000 ppm. The measurements show that fluorine can be used as a direct indicator of fluorite deposits under similar terrain conditions in the tropics.
