A method for locating ore bodies by geochemical indexes of pegmatite-type lithium deposits in the Ke'eryin area, western Sichuan, China

Funds: This research is financially supported by the Science and Technology Planning Project of the Sichuan Bureau of Geology and Minerals Resources (Grant SCDKKJXM–2018002) and Sichuan Geology and Mineral Bureau Geochemical Exploration Team Self-funded Scientific Research Special (Grant HT–KY–2022–003)
  • 摘要: 可尔因地区是松潘−甘孜成矿带的大型稀有金属矿集区之一,围绕可尔因岩体分布了大量花岗伟晶岩脉,如何在数百平方千米伟晶岩田中定位稀有金属矿脉一直是该区伟晶岩型锂稀有金属矿找矿难点之一。通过对可尔因岩体二云母花岗岩、伟晶相微斜钠长花岗岩、不同类型伟晶岩及典型矿床开展系统的岩石地球化学分析,总结了可尔因地区伟晶岩地球化学元素空间分布和变化规律,提出了寻找锂矿的特征元素指标、指示指标和品位指标等地球化学指标。特征元素指标包括Li、B、Sn、Rb、Be、Nb、Ta等元素;平面指示指标包括Cs、Tl、F、Zr、Y、ΣREE等元素及TiO2/Ta、Zr/Hf、Ta/Zr、Nb/Ta、K/Na等值;垂向指示指标包括B、U、Zr、Be、Sn、Rb、Sr、Ba、Tl、In等元素。通过特征元素指标及指示指标的值和变化规律,可辅助定位稀有金属矿化伟晶岩位置,指示矿体深部延伸情况。品位指标主要包括铝饱和指数(A/CNK、A/NK)、里特曼指数(σ)、K+Na和K/Na值等,Li品位与铝饱和度呈正相关、与碱度呈负相关,品位指标的变化趋势指示了矿体中锂的富集部位。
