摘　　要：目前,胶东金矿成矿流体研究主要集中在成矿流体的来源及其成矿过程研究,但是对于其侵位前的物化状态及分异演化研究尚浅。该文提出胶东金矿矿集区幔源成矿流体深部演化的一种形成机制,并认为胶东金矿幔源成矿流体在侵位前发生了富集作用。正是由于幔源成矿流体的富集作用才使得胶东地区形成现在规模、品位的金矿。胶东金矿幔源成矿流体的侵位机制主要受华北东部构造转折体制制约。根据胶东地区金矿幔源成矿流体分异演化特征、构造特征及现有深部探测实例表明:胶东地区在1000m以下极有可能存在另一个大型金矿带。At present, study on the ore - forming fluid of Jiaodong gold deposit is focused on the sources and miner- alization processes, but the study on physical and chemical state and differential evolution before its emplacement is not enouth. In this paper, a it has been put forward. It is set of the formation mechanism of the mantle ore - forming fluid of Jiaodong gold depos- regarded that enrichment has happened before emplacement. Enrichment of the mantle ore fluids has formed such scale and degree of Jiaodong gold deposit. Emplacement mechanism is mainly controlled by tectonic regime inversion of the North Eastern tectonic of the mantle ore - forming fluid of Jiaodong gold deposit. According to the differential evolution features, structural features, and deep exploration of existing examples of mantle ore -forming fluid of Jiaodong gold deposit, it is showed that：there is another gold belt under 1000m in Jia- odong area.
