摘要: 维拉斯托锌铜多金属矿床受米生庙复背斜南东翼的近东西向“S”型压扭性断裂构造控制，矿体赋存在接触部位的古元古界宝音图组和华力西中期花岗闪长岩体内.通过系统总结矿区地质、矿体地质以及矿床矿石结构构造、矿物及其交生、围岩蚀变、化学成分特征，认为锌铜多金属成矿作用与石英闪长岩侵入岩体关系密切，矿床形成时代为华力西中期，矿床成因类型为岩浆热液型.

Abstract: The Weilasituo Zn-Cu polymetal deposit in Inner Mongolia, occurred in the Paleoproterozoic Baoyintu formation and the Middle Variscan granodiorite body, is controlled by the E-W-trending compresso-shear fault on the southeast wing of the Mishengmiao anticlinorium. With study on the geology of orefield and orebody, the structure of ore, the mineralogy, wallrock alteration and chemical composition, it is concluded that the metallogenesis of the Zn-Cu polymetal deposit is closely related to the quartz diorite intrusion. The deposit is formed in Middle Variscan, genetically belonging to magmatic hydrothermal type.
