Abstract: Vanadium metal,renowned for its excellent physical and chemical properties,is often referred to as the "modern
industrial monosodium glutamate". As the strategic value of vanadium resources becomes increasingly prominent in new energy,
future industries,and emerging sectors,China,as an important global producer and consumer of vanadium ore,has significantly
elevated its emphasis on vanadium. Its strategic positioning has gradually shifted from a traditional metallurgical raw material
to a core mineral resource supporting national energy transition and industrial security. During the "14th Five-Year Plan"
period,vanadium was officially listed as a "strategic mineral resource," highlighting its irreplaceability. Henan Province is an
important vanadium-rich region in China,ranking sixth nationally in terms of resource distribution. It serves as a key source of
raw materials for domestic new-energy batteries,steel alloys,and related fields. The formation and distribution of vanadium deposits
in Henan exhibit distinct spatiotemporal regularity. However,systematic and comprehensive research remains relatively
insufficient due to long-term constraints such as limited geological study,inadequate exploration and utilization,and fluctuations
in international prices. Therefore,based on a comprehensive collection of geological data on vanadium deposits in Henan Prov
ince and incorporating research findings from the past five years,this study systematically summarizes the resource overview,
deposit types,stratigraphic characteristics,and development status of vanadium deposits in the region. It further provides an indepth
analysis of typical deposits regarding their host horizons,orebody characteristics,genetic mechanisms,and metallogenic
patterns. The research indicates that:① The main types of vanadian deposits in Henan are sedimentary and sedimentary-metamorphic,
with metallogenic epochs spanning the Neoarchean,Neoproterozoic,and Early Paleozoic. ② The host strata include
the Zhao'anzhuang Formation of the Taihua Group,the Meiyaogou Formation of the Luanchuan Group,the Xiewan Formation of
the Kuanping Group,and the Shuigoukou Formation of the Cambrian System. Among these,the black rock series of the Shuigoukou
Formation is the most significant vanadium-bearing horizon in Henan,primarily composed of variegated mudstone,carbonaceous
mudstone,siliceous rock interbedded with mudstone,and siliceous rock. ③ The metallogenic environment is mainly
marine sedimentation under suboxic to anoxic conditions. Mineralization was controlled by multiple episodic processes,with oreforming
materials influenced by terrigenous clastic deposition,hydrothermal exhalation,and biological adsorption. ④ Based on
the national three-level metallogenic belt division,two sub-metallogenic belts (Level Ⅳ) and eight ore concentration areas
(Level Ⅴ) have been further delineated. The distribution of sub-metallogenic belts aligns with mineralization intensity,showing
a trend of increasing strength from north to south. ⑤ Through comprehensive analysis of the metallogenic prospects in ore
concentration areas,three prospecting target zones have been preliminarily delineated within the Cambrian Shuigoukou Formation.
Sparse engineering verification indicates relatively high mineralization levels and significant prospecting potential. It is estimated
that one large and two medium-sized vanadium deposits can be identified,with an inferred V2O5 resource of approximately
1. 497 1 million tons. The research outcomes provide a valuable reference for deepening the understanding of metallogenic
patterns,achieving exploration breakthroughs,and promoting high-quality utilization of vanadium resources in Henan
Province.
