In some way, the nature of the geochemical field shows that the deep fluid took part in the energy mineral reservoir formation and mineralization.2、 In zones with the strong tectonic activity and basement faults, the elements combination of petroleum is complex and the material from deep resource can be found in which. The character of elements geochemical and carbon isotope all show that there are deep fluid components in some Energy Minerals. The material source of the water accompanying with petroleum reservoir is complex, and which with multi-sources. The character of elements geochemical shows that the uranium of Dongsheng uran ore comes from the upper crust, the greyish-green gritstone and hoary kaolinised argillaceous siltstone is important for the formation of uranium deposits,and the grey gritstone is great potential to surveying uranium deposits .
