      Abstract: Wulashan gold deposit belt,situated in the middle section of the north margin of North China platform,can be divided into 3 mineralization types,i.e.,quartz vein type (I),quartz vein-altered rock type(Ⅱ) and altered rock type(Ⅲ).Each type can be subdivided into 2 sub-types.The origin of the belt is closely related to Dahuabei granite body.The quartz vein type mineralization is located near the contact zone,0.1~0.5km to the granite.The quartz vein-altered rock type is distributed along the outer of the contact zone,1.5~2km to the granite.The altered rock type is 3~6 km to the granite.The type Ⅱ and type Ⅲ are with great potential.Especially,the quartz vein-altered rock sub-type and the complex altered rock sub-type have formed economic lodes.
