MINERALIZED BODY MODEL OF THE TUNGSTEN AND TIN ORE FIELD IN BAIGANHU, EASTERN KUNLUN, XINJIANG

The deposit type of the Baiganhu tungsten and tin ore field belongs to structural controlled high-temperature hydrothermal deposit. The geometric figure of mineralized body depends on the character of the controlled structure and host rock. The host rocks of this deposit include sericite quartz schist, quartz sanidine rock, metamorphism gabbro and granite. The mineralization is mainly the dissemination of the even thin dike.There is few differences between the mineralized rocks and the nonmineralized rocks. The replacement of mineralization phase is faint.The type of the mineral is thin dissemination hydridization and rich thin dikerock. The mineralized body model is established on the understanding of mineral character, mineral law and the data of geometric figure of ore body. In all, the correct recognition of the character of ore body is very important.
