Abstract: Miaoling gold deposit, Songxian County, He'nan Province is located in Xiong'ershan—Waifangshan metallogenic belt along south margin of North China Block. It is medium-low temperature hydrothermal deposit controlled by fragile structure.At present, the reserve resources of mine are seriously insufficient.For making a breakthrough in deep prospectivity and relieving production pressure, this study begins with metallogenic structure. Through analyzing structural features and summarizing the occurrence of the orebody, it is proposed that F8 ore-bearing structural belt is compression-torsion in mechanical property and it's structural extension is stable. The occurrence of ore bodies in the structural belt is closely related to the change of the attitude of the structural belt. The favorable occurrence positions along structural belt trend are located in the parts of trend deflection, branch composite, structural intersection and expansion. The favorable occurrence positions along structural belt tendency are located in the gently inclined section while the dip angle of the structural belt changes from steep to gentle.In addition, the spatial distribution of the ore body has the characteristics of right lateral trending. Combined with the verification of the target area, the results of this study suggest that F8 ore-bearing tectonic belt still has a stable extension and there are obvious mineralization clues in the deep, which can provide guidance for further mineral exploration.
