We obtain some new cognitions of mineralizing rule, effective prospecting method and deep forecasting for the Gejiu super Sn-Cu multi-metal deposit of Yunnan Province by systemic research in recent years.Its primary mineralizing process is repeated compound alteration by hot liquid of magma.Conformation afforded transmit alleyway and deposited space for mineralization.The wall rock condition and combination zoniferous character of mineral element lead to mineralizing multiformity.Ascertainment 3D-distributing of granite, drape and faultage conformation and lithology is the key to mineralization forecasting.It proves an effective prospecting method to combine ascertainment lithology interface and deposited roomage by gravity and magnetic survey, and multifunctional electric survey, speedy ascertainment of mineralization abnormity by geochemistry survey of sap, drill and faultage.The future deep prospecting centers around the following three aspects: (1) interbedded oxidation or nervation mineral deposit in the periphery of diggings, (2) Sn-Cu multi-metal deposit in the interface of granite or basalt and marble, (3) Cu-Sn multi-metal deposit in the alterative granite.
