About Ghoseite Root Name Group
Formula:
â—»[Mn2+Na]Z2+4Z3+]Si8O22W2
The ghoseite minerals belongs to the Sodium-(magnesium-iron-manganese) amphibole subgroup and is defined with
A(Na+K+2Ca) < 0.5 apfu,
B(NaMn)
0.5 apfu< C(Al+Fe3++2Ti) < 1.5 apfu
The root-name mineral, ghoseite is defined with Mg, Al and (OH) as the dominant elements. Minerals in this root name with other dominant elements are named with pre-fixes in accordance with the guidelines establised in the 2012 amphibole nomenclature.

Name:
Ghoseite are named for Subrata Ghose (b. 1932), Emeritus Professor at the University of Washington, Seattle. Ghoseite was established as a new root name in the 2012 amphibole nomenclature (Root-name 11 in the amphibole nomenclature report). Amphibole with this composition was named parvowinchite from 1997 to 2012.
