Halloysite
Halloysite is a hydrous aluminum silicate mineral with the chemical formula Al2Si2O5(OH)4. It belongs to the monoclinic crystal system and is classified as a phyllosilicate in the Strunz classification (9.ED.10). The mineral typically exhibits a white to pale yellow color, a waxy to pearly luster, and a soft, earthy texture. It has a Mohs hardness of approximately 1 to 2 and a low to moderate density. Halloysite is commonly found in weathered igneous and metamorphic rocks, and it is known for its layered, clay-like structure, which gives it a platy or fibrous appearance in some forms.

Etymology
Halloysite is named after Jean Baptiste Julien d'Omalius d'Halloy, a French geologist who first described the mineral. The mineral was later renamed by the International Mineralogical Association.
Geological genesis
Halloysite typically forms through the weathering of aluminum-rich silicate minerals in igneous and metamorphic rocks. It is commonly associated with low-temperature alteration processes and is often found in clay deposits.
