Abstract:Vanadium is an essential strategic metal widely used in metallurgy, aerospace, and new-energy battery industries. The vanadium deposits are mainly magmatic and sedimentary types in China. Sedimentary vanadium deposits take up 87% of the total reserves in China. Most of the sedimentary vanadium deposits occur in marine carbonaceous shales, which have broad spatial distribution and have many metals as by-products, such as Mo, U, Co,Se, etc.. This type of deposit is considered to have significant resource potential in the future. However, due to its small number of large deposits, low ore grade and high mining cost, the utilization of sedimentary vanadium ores in China has been subdued. Based on previous studies, this paper summarizes the spatial-temporal distribution of sedimentary vanadium deposits in China, and defines three sedimentary vanadium metallogenic belts: the northern margin of the Tarim Platform, the northern margin of the Yangtze Platform and the southeastern margin of the Yangtze Platform. Comprehensive analysis shows that the formation of sedimentary vanadium deposits was jointly controlled by specific strata, lithology, and paleogeographic conditions. Abundant supply of ore-forming materials, suitable paleogeographic and paleoceanic redox conditions, and prosperous biological activities are key factors that lead to the formation of sedimentary vanadium deposits. The Cambrian carbonaceous, silicic muddy shales are widely occurred along the northern and southeastern margin of the Yangtze Platform and considered as a potential area for exploration of sedimentary vanadium deposits in China.
