Allophane
Allophane is an amorphous mineral with the chemical formula Al2O3(SiO2)1.3-2.0·2.5-3.0H2O, indicating a variable composition of aluminum oxide, silicon dioxide, and water. It lacks a defined crystal structure, distinguishing it from crystalline minerals. Allophane typically exhibits a white streak and has a dull, earthy luster. Its hardness is relatively low, and its density is moderate. Classified under the Strunz system as 9.ED.20 and the Dana system as 71.1.5.1, it is considered a member of the hydrous aluminum silicate group. Allophane is commonly found in weathered or altered rock environments.

Etymology
Named after other.
Geological genesis
Allophane is typically formed through the weathering of silicate minerals, particularly in soils and altered volcanic materials. It is commonly associated with secondary processes in low-temperature environments, where aluminum and silicon are mobilized and reprecipitated under conditions of high water content.
