Prospecting potential of medium-fine-grained rock-type lithium resources in the Xianghualing orefield,Hunan Province,China
This study aims to explore the distribution characteristics and occurrence patterns of lithium in medium-fine-grained rocks and its paragenetic or associated relationship with minerals such as tungsten,tin,niobium,tantalum,beryllium,and rubidium.Hence,it analyzed the distribution characteristics and diagenetic and metallogenic processes of nonferrous-rare metals in the Xianghual-ing orefield.With the exposed granitic rock masses as the center,this study divided three ore-forming sections of rare metal lithium,i.e.,the Laiziling-Nanjichong,Jianfengling-Xianghuapu,and Tongtianmiao-Yaoshanli ore-forming sections.Moreover,lithium-rich mineralized bodies were discovered in the medium-fine-grained rocks of the former two ore-forming sections.Lithium converges and ac-cumulates in the interior and top of medium-fine-grained granitic rock masses,at the automorphism and alteration positions of high-em-placement apophyses and vein fronts and edges,or in the areas enclosed by silicon-rich quartz veins at the contact zone with silicon-rich surrounding rocks.Dividing these mineralization and alteration sections serves as a crucial approach for exploring medium-fine-grained rock type lithium ore bodies in the Xianghualing orefield.
