Ore concentration area in northwestern Guangxi is one of the important base of nonferrous metals in China,With the good metallogenic conditions, larger ore prospecting potential, high degree research.The paper briefly introduces the geological background and deposit distribution in the ore concentration area.Taking the Nandan-Kunlunguan metallogenic belt is the key,summariaes the deposit types ,the zoning characteristics of wall rock alteration and minwealization.Proposed the output of the ore field and ore deposits, on the one hand,is controlled by the favorable tectonic position ,such as the intersection uplift position of NW and NE tectonic,anticiline core,the turn position of NW fault and fold, the local uplift position of the anticline axis.On the other hand,is controlled by the intrusive tectonic of granite. Surrounding the concealed granite rock,wall rock from inside to outside shows greisenization→skarn,hornfels→feldspathization, tourmalinization, silicification, sericitization, carbonatization→sericite, chlorite, carbonate; mineralization assemblage shows the normal zoning characteristics of high-temperature W-Mo metallization,Zn-Cu-Sn metallization→High-medium temperature Sn polymetallic metallization→Medium -low temperature Pb-Zn metallization→Low temperature Sb-Hg-As metallization.Low temperature W-Sb deposit superimposed on the skarn type Zn-Cu orebodies near the granite body,show the reverse zoning characteristics in the late mineralization.The composition of sulfur, carbon, oxygen isotope and spatial variation rule show that migration direction of ore-forming material is from near to far from granite orebody. It is confirmed that the genesis of deposites in the ore concentration area belong to magmatic hydrothermal origin.Establed metallogenicl model ,based on the properties of ore-bearing rock,the position of orebody output, type and form of ore deposit, reflects directly the metallogenic characteristics of Nandan-Kunlunguan metallogenic belt,which has importantment guiding significance for the regional prospecting practice.
