摘　　要：通过对杂岩体岩石地球化学、稀土元素组合、岩石类型、同位素特征分析，认为水泉沟碱性杂岩体与金矿床存有密切成生关系．杂岩体的成岩过程也是Ａｕ活化、迁移、富集的成矿过程．杂岩体的形成时代是海西期—燕山期，其形成是由于多期次岩浆活动并多次同化围岩而成．同时对Ａｕ在岩体中的活动和金成矿模式进行了讨论．huiquangou 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
