WebApr 11, 2024 · These show that weathering of granite is accompanied by Mg loss and formation of secondary Mg-bearing clay minerals, which preferentially adsorb heavy Mg isotope. This is reinforced by the positive relationship between δ 26 Mg values and the content of kaolinite and gibbsite during the early weathering stage. Particularly, the soils … Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (Y-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amo…
