Researches to the gold-bearing quality of sedimentary and magmatic rocks show that most of these rocks have more gold content than the average of the upper crust. Further evidences are quoted to support the view that fluids exist in shallow crust have the ability resolve some gold. Moreover, in the convergent compression, deep melting of the lower lithosphere can bring some Au and mineralization materials and move up to upper crust. Regional faults, which formed in geosynclinal and diwa periods, controlled the partial distribution of intrusions and gold mineralization belts, i.e.

区域地层和岩浆岩的含金性表明，岩浆岩和大部分地层均具较高的金异常含量，而进一步的研究表明浅部地壳的流体对地层中的金具一定的溶解和搬运迁移能力；而在汇聚挤压构造体制下由深熔作用生成的岩浆可以从岩石圈深部携带部分金和其它成矿物质并迁移到地表浅部，地槽期和地洼期形成的区域断裂构造共同控制了中新世岩浆的侵入和金成矿带的分布。
