摘要
通过地质勘查工作和综合研究,发现大王顶金矿床金矿体主要产于花岗斑岩体内、或是斑岩体顶、底部外接触带中;有构造破碎蚀变(花岗斑岩)岩型(产出黄铁绢英岩型矿石)及含金硫化物石英脉型矿石)两类矿体。矿床成因类型属岩浆热液金矿床大类中的重熔岩浆热液金矿床。
By the work of geological exploration and the comprehensive study, the gold orebodies of Dawangding gold deposit are maily located in the middle, top or the external contact zone in the bottom of granite-porphyry body. There are two types of ore body which are JuanYing of yellow iron deposit and quartz vein deposit of gold bearing sulfide produced by fractured alteration rock （granite-porphyry）. The type of deposit belongs to remelting magrnatic hydrothermal gold deposit which is the branch of magmatic hydrothermal gold deposit.
