基于野外地质调查的赣州宁都地区非矿区花岗伟晶岩型锂辉石矿床成矿潜力分析OA

As an important source of lithium,spodumene minerals play a more and more important role in industrial production and the development of science and technology.As an important carrier of lithium-bearing minerals,granite pegmatite is the primary prerequisite for the analysis of the metallogenic potential of lithium deposits.Based on the field geological survey,combined with the structural and mineral alteration marks summarized by predecessors,the granite pegmatite veins and spodumene minerals exposed in the non-mineral right areas of Jiangjun'ao-Qingtang,Pingbuling-Dongjiapai and Shishang-Huangshi areas in Ningdu area of Ganzhou,Jiangxi Province were investigated and analyzed.36 field geological survey routes show that the granite pegmatite veins in Pingbuling-Dongjiapai area are widely exposed,the veins are wide and extended far away,and fractures are interactively developed.Geochemical analysis shows that the grade of Li element in some dike samples is more than 1%,which can be used as a good occurrence point of lithium deposit.The discovery of spodumene minerals in dikes indicates that the exposed granitic pegmatite dikes in Ningdu area have good ore-forming ability.The field geological survey and Li element grade in Shishang-Huangshi and Jiangjun'ao-Qingtang survey areas show that the metallogenic potential is small or non-metallogenic.
