The Rossing deposit is a world-class leucogranite -type uranium deposit, with airborne radiometric anomalies indicating the presence of multiple mineralization zones in the Rossing area, including SJ, SH, SK, Z17, Z19, and others. In this study, it was discovered that although all these mineralization zones are leucogranite -type uranium deposits, they exhibit significant differences in the mineral composition of the mineralized leucogranite. Uranium minerals during the magmatic stage in the Rossing deposit are primarily represented by euhedral and subhedral magmatic crystalline primary minerals and can be classified into three combinations:①uraninite + zircon + apatite combination, mainly distributed in the Z17, Z19, and SJ areas;②coffinite,uranothorite +sphene+ apatite combination, mainly found in the SH area;③Betafite combination, mainly distributed in the SK and SH areas. Currently, the main mining focus in the Rossing deposit is on the first combination. The different mineral combinations may originate from variations in the crystallization differentiation degree of the mineralized leucogranite. The uranium mineralization in the study area can be divided into three stages: magmatic stage, hydrothermal stage (reducing conditions), and epigenetic leaching stage (oxidizing conditions). The magmatic stage is the primary ore-forming stage, the hydrothermal stage (reducing conditions) is relatively weak, the predominant uranium minerals formed are vein-type uraninite, as well as vein-type pyrite and carbonates. while the epigenetic leaching stage (oxidizing conditions) is stronger in the SH and SJ areas, the main uranium minerals formed are uranophaneSand hematite. The electron probe chemical age of uraninite in the study area is 507 Ma, which is basically consistent with the LA-ICP-MS U-Pb age of uraninite obtained from Zone 18. This indicates that the chemical age of uraninite can represent both mineral crystallization age and magmatic mineralization age, indicating that the effective mineral crystallization age can be obtained from the electron probe chemical age of uraninite in the study area. Uraninite, coffinite, and easily extractable uranium minerals, as well as betafite and sphene, which contain uranium but are difficult to extract, can provide a uranium source for hydrothermal processes. In the SH area, further exploration should focus on finding coffinite,uranothorite +sphene+ apatite combination in mineralized leucogranite. SH area have the potential for exploring hydrothermal-type uranium deposits.
