In recent years, significant progress has been achieved in the exploration of Huayangchuan uranium polymetallic ore, and the distribution of shallow ore bodies has been mainly identified. However, the deep tectonic development and complex terrain of the Huayangchuan area in the North Qinling Mountains, as well as a lack of early research on the characteristics of the deep tectonics, have restricted the deep prospecting breakthrough in this area. Based on available geological data, a comprehensive analysis has been conducted on the deep structural characteristics of the Huayangchuan uranium polymetallic mining area. The study reveals that the deep extension of the Huayangchuan ductile shear zone provides crucial pathways for the migration and emplacement of uranium sources. Furthermore, the contact of the Huashan rock body on the northern side of the mining area exhibits a gentle gradient, forming a "chair-like" morphology, which favors the enrichment of uranium sources. Based on these findings, it is believed that there is significant potential for uranium ore exploration within at least 1,500 meters of depth in the Huayangchuan uranium mining area.
