It occurs together with allophane, quartz, cristobalite, gibbsite, vermiculite and limonite. The mineral gibbsite is named after him. It occurs in association with basaluminite, gibbsite, epsomite, gypsum, celestine, dolomite and goethite. For example, dissolution of albite may result in formation of gibbsite. It is composed mainly of hydrated alumina minerals such as gibbsite [Al(OH) or AlO . Diaspore, along with gibbsite and boehmite, is a major component of the aluminium ore bauxite. Gibbsite and bayerite are monoclinic, whereas doyleite and nordstrandite are triclinic forms. The structure of gibbsite is interesting and analogous to the basic structure of the micas. The tube walls are formed by continuous (gibbsite) sheets and orthosilicate anions ( groups). Minerals formed in laterite nickel deposits include gibbsite. Gibbsite has a typical metal hydroxide structure with hydrogen bonds. Under most conditions, gibbsite is the most chemically stable form of aluminium hydroxide.
