摘　　要：八卦庙金矿床的矿石品位与其石英脉发育程度和破碎程度、共生硫化物的含量成正比,与脉体的厚度、共生硫化物的粒度成反比;节理脉的含金量比顺层脉的含金量高;石英细脉的含金量高于脉旁围岩的含金量数倍至十多倍,但含金石英脉不能单独构成工业矿体.据此,作者首次提出金矿化类型属于细脉浸染型金矿,揉皱石英细(网)脉破碎带是此类金矿的一种重要而直观的找矿标志.Ore grade in Baguamiao gold deposit is in direct proportion to the development and broken degree of quartz vein and to the content of co-existed sulphide,and is in inverse proportion to vein thickness and the grain size of co-existed sulphide. The gold content in joint vein is higher than that in bedding vein. The gold content is several to more than ten times of the content in surrounding rock nearby. Nevertheless industrial ore body isn't alone consisted of gold-quartz vein. In view of the points mentioned above .the authors put forward that the gold mineralization type is of veinlet disseminated gold deposit. Fracture zone with kneaded and folded quartz stockwork veinlet is an important audio-visual indicator for this type of gold deposit.
