NOMENCLATURE PROPOSALS APPROVED IN OCTOBER 2017

Gatelite supergroup

A new classification and nomenclature scheme has been approved for the minerals of the gatelite supergroup. The supergroup is dived into three groups: gatelite group, västmanlandite group, alnaperbøeite group.

Schoonerite group

A new classification and nomenclature scheme has been approved for the minerals of the schoonerite group. Currently the group includes three mineral species: schoonerite, wilhelmgümbelite, and schmidite.
