| Abstract: | Using geological and geochemical methods and starting with analysing the data of the change of elements of primary halos from Dachang orefield, the authors place emphasis on discussing the source of ore-forming materials of the deposit and put forward that such ore-forming elements as tin, silver, bismuth, tungsten come mainly from granitic magma, Zinc mainly from strata, and copper, lead,antimony,arsenic, sulphur not only from magma, but also from strata. The intrusion of biotite granite in Yanshanian stage is an important factor of mineralization in Dachang orefield. The granite not only provides part of ore-forming materials, but also initial ore-forming hydrothermal solution or fluid. |
