The mining area is primarily underlain by the Halabayigou Formation of the Ordovician Naij Tal Group, with minor exposure of the Meso-Neoproterozoic Wanbaogou Group. The Wanbaogou Group occurs mainly as lenticular bodies in the northern part of the mining area. The outcrops have a surface width of 50–500 m and a length of ~5 km. The overall attitude of the unit dips northward at an angle of 53–77°. Lithologically, it is composed of microcrystalline marble and metasandstone, with contact between them occurring along ductile faults. The Halabayigou Formation is the dominant stratigraphic unit and serves as the ore-bearing sequence. This formation is divided into three lithological members from bottom to top: The Lower Member consists primarily of a carbonate sequence of light-gray limestone with locally well-developed schistosity, with a thickness exceeding 100 m. The Middle Member is the main V-ore-bearing horizon. The lower part comprises a yellowish-brown to gray-black argillaceous–calcareous slate, which has a fault-contact relationship with the underlying Lower Member. The middle part features interbedded thin-layered black carbonaceous and gray-black carbonaceous siliceous slates with occasional thin limestone interlayers. The upper part consists of interbedded dolomitic limestone and argillaceous–calcareous slate. The Upper Member is characterized by an interbedded sequence of argillaceous–calcareous slate and limestone, with thin sandstone layers exposed in the center.
Overall, 37 V ore bodies were identified within the four V mineralization and alteration zones studied. The V ore bodies generally range in length from 98 to 3720 m and in thickness from 0.7 to 15.03 m, with V2O5 grades of 0.5%–2.92%. The ore bodies exhibit simple morphology, layered organization, and significant variations in thickness and grade along the strike and dip, characterized by pinching and swelling. The M1 ore bodies in the HSI V ore zone and the M3-2, M3, and M3-5 ore bodies in the HSIII V ore zone are relatively large in both length and scale, representing the main ore bodies. The V ore bodies are hosted in black carbonaceous and carbonaceous siliceous slates, with the wall rock comprising limestone and argillaceous–calcareous slate. The overall estimated V ore resources in the mining area amount to 15,586 thousand tons, with an average deposit grade of 0.80% and V2O5 content of 126,625 tons, representing a medium-sized deposit.
