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.

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.
