Abstract Tianjinghu Pb-Au deposit, located at the intersection between the EW-trending Bengbu uplift and the NNE-trending Tan-Lu fault zone, is a medium-size Pb-Au symbiotic deposit. The magmatic activity in the area is well developed, and the metallogenic conditions are good. In order to analyze the ore-controlling factors of Tianjinghu Pb-Au deposit, and establish its metallogenic model, the authors summarized the metallogenic geological characteristics and investigated the characteristics of ore-controlling factors such as stratum, structure and magmatic rocks in Tianjinghu Pb-Au mining area and other areas of wuhe, based on recent new results and previous data. The main ore-controlling factors of the deposit are NNE-NE-trending and SN-trending fault structures. The sedimentary-metamorphic rock system of Xigudui Formation is an ore-forming stratum. The intermediate-acidic vein rocks and large-scale rock masses are of great significance to the formation of ore-bearing hydrothermal fluids and the activation and migration of ore-forming materials. Xigudui Formation and Wuhe Group provide space for fault activities and some material sources for gold deposits. This achievement improves the metallogenic and ore-controlling pattern of gold deposits in Wuhe area, and also provides some theoretical basis and reference for the search for the same type of deposits in this area.
