Abstract: [Objective] The Xinjiang region is rich in mineral resources, including petroleum, natural gas, coal, iron, ect. However, bauxite resources have historically been scarce, with only a few scattered occurrences identified along the southern Tianshan Mountains and the northwestern margin of the Tarim Basin. In 2025, bauxite deposits were discovered in Kalakunlun Orogen. This breakthrough confirmed—for the first time—the presence of industrial-grade bauxite bodies in the Kunlun Orogen, expanding the prospective exploration area for bauxite across Xinjiang Province. The Xinjiang bauxite exhibits strong similarities to deposits commonly found in North and South China: developed on carbonate platforms and are genetically classified as karst-type bauxite. Given the widespread distribution of carbonate platform sediments throughout Xinjiang, the region holds considerable potential for further bauxite development. There is an urgent need to conduct detailed research on this newly discovered deposit to preliminarily clarify the bauxite mineralization processes, elucidate its metallogenic mechanisms, and provide a solid scientific foundation for subsequent bauxite exploration in Xinjiang. [Methods] This study targeted the bauxite occurrence in the Kalakunlun Orogen area, employing an integrated multi-disciplinary approach including sedimentology, stratigraphy, paleontology, mineralogy, and geochemistry. [Results] The findings reveal that bauxite is developed under warm, humid tropical climatic conditions, influenced by regional tectonic evolution and multi-phase sea-level fluctuations driven by global glacial-interglacial cycles. [Conclusion] The bauxite layer preserves a complete regressive-transgressive sedimentary cycle. Regression exposed the carbonate platform, creating conditions conducive to bauxite formation through intense weathering and leaching processes, while subsequent transgression resulted in the deposition of overlying organic-rich carbonaceous mudstone. Sedimentological and geochemical characteristics document frequent sea-level oscillations and climatic change, which established optimal prerequisites for enhanced leaching and metallogenesis in this area. This discovery not only addresses a key regional metallogenic gap but also underscores the broader exploration potential for carbonate-hosted karst bauxite in tectonically active orogenic settings like the Kunlun Orogen.
