Analysis on the Characteristics and Prospecting Potential of the Jiguanzhai Fluorite Deposit in Dayu County,Jiangxi Province
摘要
Abstract
Located in Dayu county,Jiguanzhai is within the Xiangdong-Gannan-Yuedong fluorite ore cluster.This paper analyzes the geological characteristics of the deposits and ore-controlling factors in Dayu Jiguanzhai mining area,and summarizes the prospecting indicators and prospecting potential.The analysis revealed that the study area features well-developed fracture structures,including five NE-striking fault structures(F1-F5).Fluorite ore bodies are predominantly found within the northeast-striking fault structure F2.In addition,the CaF2 grade of the main ore body V1 ranges from 15.25%to 77.64%,with an average value of 39.00%.It is proposed that the coupling sites of"Lithology(Niujiaohe Formation metamorphic feldspar quartz sandstone,metamorphic medium-to-fine-grained feldspar lithic(impure)sandstone),+Structure(NE-striking fault structures)+Magmatic rocks(Late Jurassic Yanshanian biotite granite(or biotite monzogranite))"within the Jiguanzhai fluorite deposit reconnaissance area constitutes a favorable locus for fluorite formation.It is observed that the ore body V1 exhibits a gradual thickening along the dip,with an increasing ore grade trend.The ore body remains unpinched along the southwest-northeast strike,suggesting favorable prospecting potential.The analysis of deposit characteristics and prospecting potential is of substantial guiding value to ore exploration endeavors.关键词
