Abstract: On the base of survey and analysis, combined with feature of metamorphic core complex structure, we studied on the metallogenic regularity and ore-controlled mark for gold deposit in Tongyu ore cluster region of Xiaoqinling mineralized belt.The results show that the metallogenic substances come from Taihua group stratum, and gold deposits are controlled by late magma and structure, displayed clear ore-controlled characteristics of metamorphic core complex structure system and its stripping decollement structure.Fotouya-Shizibao, Dongjiaogou-Fotouya, Yuewangmiao-Wangpaigou district, and anticlinorium pitching end in this region are important exploration targets, needing further geological work, which can provide a model for exploration in old mine area.It has important practice significance for prospecting deep gold deposit in old ore region and making the deep gold exploration in west Xiaoqinling come to a new stage and achieving exploration breakthrough.
