About Herderite Group
Member of:
Name:
The group has its name after first described mineral in the group, herderite, originally described from Sauberg Mine, Germany.
The Herderite Group of the Gadolinite Supergroup is defined on the basis of the tetrahedral cation (P5+ or As5+) at the T site . It is, according to the new classification established by IMA in 2016 (IMA 16-A), divided into two subgroups: the Herderite Subgroup and the Drugmanite Subgroup.
