The Helvine Group of minerals is a group of four berylosilicates that may be considered a subgroup of the Sodalite Group. Helvine is probably better known by its historical synonym Helvite. The IMA officially recognized name from the 2012 IMA list is Helvine, not "Helvite", although Helvite may be more common in literature. |
