Geological Characteristics, Genesis and Resource Utilization of the Wangjiabian Kaolin Deposit in Jiaxian, Shaanxi Province

Ordos is a Mesozoic-Cenozoic sedimentary basin developed on the basis of the Paleozoic North China craton, and is an important multi-energy and mineral resource-rich and concentrated location and production area in China. The lower Jurassic Fuxian Formation is the product of filling in the eroded and dissected surface formed by the Indosinian movement on the Triassic uplift. The Wangjiabian kaolin deposit in Jiaxian, Shaanxi province is hosted in the sandstone-claystone structure of "the fine Fuxian" of the Lower Jurassic Fuxian Formation in the eastern margin of Ordos Basin, with great potential for mineral exploration. However, the geological characteristics, ore deposit genesis, and resource utilization of the deposit are still unclear, which restricts the exploration and development of kaolin deposit in this area. Based on the geological characteristics of this kaolin deposit, this paper conducted tests the chemical composition of SiO₂, Al₂O₃, Fe₂O₃, TiO₂, K₂O, Na₂O, CaO, MgO, MnO, volatile loss, whiteness and other physical properties, as well as the firing shrinkage rate, heat resistance, plasticity index, dry shrinkage rate, firing temperature and other physical properties, discussed the genesis and tectonic setting, summarized the exploration indicators, preliminarily evaluated the quality of the ore stone, and suggestions for resource utilization were proposed.
