Abstract: Shuiquangou alkali complex, intruding in the metamorphic series of Achean Sanggan group,is located on the south of Shangyi-Chicheng supercrustal fault in the north margin of North China platform. Lithologically,it can be classified into alkali syenite and monzonite.The gold deposits in it are genetically related to the complex. The complex was formed by multistage magmatic activities and assimilation with the wall rocks during Hercynian to Yanshanian stages.The diagenetic process of the complex is also the metallogenic process of Au through mobilizing,migrating and enriching.
