Abstract:At present, study on the oreforming fluid of Jiaodong gold deposit is focused on the sources and mineralization processes, but the study on physical and chemical state and differential evolution before its emplacement is not enouth. In this paper, a set of the formation mechanism of the mantle oreforming fluid of Jiaodong gold deposit has been put forward. It is 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 oreforming fluid of Jiaodong gold deposit. According to the differential evolution features, structural features, and deep exploration of existing examples of mantle oreforming fluid of Jiaodong gold deposit, it is showed that:there is another gold belt under 1000m in Jiaodong area.
