'''Crossite''' is an inosilicate double chain sodic [amphibole](/source/amphibole) and is a rare [silicate mineral](/source/silicate_mineral) belonging to the [riebeckite](/source/riebeckite) group. It is considered an intermediate between the amphiboles [glaucophane](/source/glaucophane) and [magnesioriebeckite](/source/magnesioriebeckite), which form a series.<ref>[http://www.galleries.com/minerals/silicate/riebecki/riebecki.htm RIEBECKITE (Sodium Iron Magnesium Silicate Hydroxide)<!-- Bot generated title -->]</ref> [IMA](/source/International_Mineralogical_Association) status: discredited 1997.

Crossite is named after [Charles Whitman Cross](/source/Charles_Whitman_Cross), an American [USGS](/source/United_States_Geological_Survey) petrologist.
