Eveite is a very rare secondary mineral found encrusting cavities and fractures in deposits containing
iron-manganese oxides and carbonates, associated with hausmannite,
dolomite and calcite.
At the type locality, Långban, Värmland, Sweden, eveite occurs in fissures in a metamorphosed iron–manganese orebody, associated with akrochordite, manganoan hornesite and hausmannite.
At Sterling Hill, New Jersey, USA, eveite occurs in a metamorphosed stratiform zinc orebody, associated with willemite and sarkinite.
