Hematolite occurs in fissures in metamorphosed limestone in iron-manganese
orebodies, associated with allactite, manganosite,
baryte and fluorite
At the type locality, the Moss mine, Filipstad, Värmland, Sweden, hematolite occurs in veinlets or cavities in crystalline limestone of a stratabound manganese-iron ore deposit. Associated minerals include magnetite, jacobsite, manganosite, fluorite, calcite and baryte. Hematolite is known only from this area (Mindat, AM63.150-159).
Hematolite alters to manganite (Mindat).
