Abstract: The Zhazixi tungsten-antimony deposit in Hunan Province is a large antimony deposit which has associated tungsten mine in Western Hunan.The study on its metallogenic structure is still less，which restricts the further prospecting.The regularity of tectonic ore-controlling and the sequence of tectonic evolution of this area have been summarized through regional ore-controlling structure analysis， field structure and ore body geological survey， compilation and mapping of exploration data over the years， occurrence statistics of geological bodies and composition analysis of ore bodies. The results show that ore deposits distribution is main controlled by the positive structure.The type of ore-controlling structure in mining area is "cross" type. Antimony orebody has superiority trend in NWW and NNW trending，tungsten orebody has superiority trend in NEE trending. Antimony orebody has the lateral trending in SE， and the tungsten orebody is in NE. Subsidiary fractures of F3 in the hanging wall is the host structure for antimony orebody. Antimony and tungsten formed in different structure-mineralizing stages and formation of tungsten is earlier. Mineralization center is in the south of the mining area.The deformation-metallogenic sequence in mining area can be summed up as follows: NE trending anticlinorium of the regional tectonics uplifted in Caledonian； NEE trending coaxial superimposed fold in the cover and basement formed in the first stage of Indo-Chinese epoch； NE trending tungsten orebody formed in the second stage of Indo-Chinese epoch； NNW-NWW trending antimony orebody formed in the third stage of Indo-Chinese epoch； NEE trending ore-breaking structure formed in Himalayan Epoch. Based on the study of geological characteristics， structural ore-controlling regularity and vertical mineralization zoning regularity of the deposit，it is considered that the deep part of the mining area has good prospecting prospects and two prospecting target areas are obtained:No.1 prospecting target area is located in the SE of No.9 antimony orebody， between No.2 and No.6 exploration lines and the vertical elevation is from -750 m to -900 m； No.2 prospecting target area is located in the NE of No.13 tungsten orebody，between W10 to W12 exploration lines and the vertical elevation is from -270 m to -370 m.
