马尔康党坝锂辉石矿位于松潘-甘孜造山带、巴颜喀拉造山带之马尔康复式向斜之南端.矿区出露三叠系地层,断裂、褶皱构造较发育,岩浆岩以燕山晚期二云二长花岗岩为主,是花岗伟晶岩脉的母岩.锂辉石矿体呈大脉状产出,矿石矿物有锂辉石、钽铌铁矿、锰锂矿等,脉石矿物有石英、微斜长石、钠-更长石.矿石结构为细粒-中粒结构,次为交代结构、熔蚀结构.矿石构造以块状构造为主,次为似斑状、浸染状和条带状构造.围岩蚀变主要为锂云母化、白云母化和黑云母化,成因类型为伟晶岩矿床.%Barkam county Dangba spodumene deposit is located in Songpan-Ganzi orogenic belt, the southern tip of the Barkam of the Bayan Har orogenic belt. The mining area outcrops of Triassic strata. Fractures and fold structures are developed. Magmatic rocks contains mostly the late Yanshanian the dimicaceous adamellite, that is parent rocks of granitic pegmatite veins. The orebodies are the large vein outputs. The ore minerals are spodumene, tantalum-niobium-iron ore, lithium manganese ore, and so on. Gangue minerals are quartz, feldspar, albite-oligoclase. The ore structures have fine-grained-medium-grained structure, and then account structure, corrosion structure. Ore constructed to massive structure based, and then porphyritic, disseminated and banded structure. Wall rocks alteration mainly includes lepidolitization, muscovitization and biotitization. Genetic type is pegmatite deposits.
