摘要
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,出露三叠系地层,断裂、褶皱构造较发育,岩浆岩广泛分布,以燕山晚期二云二长花岗岩为主,是花岗伟晶岩脉的母岩。成因类型为伟晶岩矿床。含锂辉石花岗伟晶岩基本上全脉锂矿化,矿体形态简单和伟晶岩脉基本一致。矿体由北西向-南东横穿整个矿区。区内发现的锂辉石矿体主要表现为细晶、中晶结构特征,矿石构造以块状构造为典型特征,矿体围岩蚀变以锂云母化、白云母化、黑云母化为主要特征。
Spodumene quarries in songpan ganzi orogenic belt,balyanlkalla orogenic belt in his rehabilitation of the southern tip of syncline,outcropped Triassic strata,fracture and fold structure,magmatic rocks are widely distributed,mainly two Yunerchang late yanshanian granite,granite is giant crystal dike rocks.Genetic types of pegmatite deposit.Lithium pyroxene granite pegmatite basically all lithium mineralization of arteries and veins,orebody shape simple and wei jing dike are basically identical.Orebody from north west-south east across the entire mining area.Area of spodumene ore body found mainly for fine grain,microtek structure characteristics.Ore structure block structure as the typical characteristics.Ore wall rock alterations to the lithium mica,white mica,black mica into main features.
