龙古矿床是川西可尔因花岗伟晶岩田内近年来新发现的一处中型锂矿床,为了进一步发掘该矿床锂找矿潜力,本文在矿床详查工作的基础上,研究了该矿床代学和阿拉伯两个矿段不同类型花岗伟晶岩的空间分布特征,发现了不同类型伟晶岩围绕可尔因岩体呈三维立体分带的特征,对比分析了代学和阿拉伯两个矿段各类伟晶岩表现出不同的分带结构.据此通过判断伟晶岩类型,依据伟晶岩类型分带结构,定位伟晶岩地质位置,推断锂成矿有利方向,指导矿床进一步找矿,且对可尔因低剥蚀地区稀有金属找矿工作提供了一定的指导意义.
The pegmatite zoning characteristics and prospecting potential analysis of Longgu lithium deposit in Jingchuan County,Sichuan Province
Longgu lithium deposit is a recently discovered medium-sized lithium deposit in the granitic pegmatite field of Keeryin,western Sichuan.To further explore the lithium prospecting potential of this deposit,based on detailed investigation of the deposit,this article studied the spatial distribution characteristics of different types of granite pegmatites in Daixue and Alabo ore sections of the deposit.It was found that different types of pegmatites exhibit a three-dimensional zonal distribution around the Keeryin rock mass.Comparative analysis of the zoning structures of various types of pegmatites in Daixue and Alabo ore sections was conducted.Based on this,lithium ore-favorable directions were inferred by judging the types of pegmatites and locating the geological positions of pegmatites according to their zoning structures.This study provides guidance for further prospecting of the deposit and offers certain guiding significance for the exploration of rare metals in low erosion areas of Keeryin.
