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.
