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.

Key words： Tianjinghu Pb-Au deposit medium-size deposit metallogenic geological characteristics ore-controlling factors Wuhe County of Anhui Province
