Effect of Karst Geomorphology on the Sedimentary Mineralization and Geochemical Distribution of Bauxite: An Example from the Xiaoyuan Area in Qingzhen, Guizhou Province

Bauxite, in central Guizhou, is predominantly karst bauxite, but there insufficient research on the effect of paleogeomorphology bauxite development. Xiaoyuan also a and high- low-iron deposits exist study area. This conducts geological modeling using controlled-source audio-frequency magnetotelluric (CSAMT) data drill core data. The effects deposition mineralization are evaluated by assessing paleogeomorphology, conducting mineralogical analysis cores at different locations, determining geochemical distribution characteristics elements horizontal vertical directions. Combined with previous results, we propose two metallogenic processes high-iron bauxite. findings significant for understanding mechanism formation.
