Halloysite is a 1:1 aluminosilicate clay mineral with the empirical formula Al2Si2O5(OH)4. Its main constituents are aluminium (20.90%), silicon (21.76%) and hydrogen (1.56%). Halloysite typically forms by hydrothermal alteration of alumino-silicate minerals.[4] It can occur intermixed with dickite, kaolinite, montmorillonite and other clay minerals. - http://en.wikipedia.org/wiki/Halloysite
