About Ferri-ghoseiteHide

Formula:
☐[Mn2+Na][Mg4Fe3+]Si8O22(OH)2
The ghoseite-root name group belongs to the Sodium-(magnesium-iron-manganese) amphibole subgroup and is defined with

A(Na+K+2Ca)< 0.5 apfu,
B(NaMn)
C0,5 apfu<(Al+Fe3++2Ti) > 1.5 apfu

Ferri-ghoseite is defined with:
C2+ position: Mg dominant
C3+ position: Fe dominant
W position: (OH) dominant

Colour:
straw yellow, pale orange
Lustre:
Vitreous
Hardness:
Specific Gravity:
3.12 (Calculated)
Crystal System:
Monoclinic
Name:
Named after Dr Subrata Ghose (1932-2015), Mineral Physics
Professor at the University of Washington, Seattle, and promoter of girls' education in India.
The material from the type locality was originally described by Dunn & Roy (1938) as "tirodite". The description provided did not meet modern standards for describing a new mineral specimen, and the chemical composition of the "tirodite" varies within too wide boundaries to be considered one mineral only (see Bilgrami, 1954). The name was eventually mostly used for manganoan cummingtonites (see Leake 1978) without taking into account the Na and Fe3+/Al content from the original description. In the 1997 amphibole nomenclature (Leake et. al. (1997)), the name tirodite was discredited as a synonym of manganocummingtonite.

The material described by Dunn & Roy (1938) was re-investigated by Oberti and Ghose (1993), and this material was named parvowinchite in the 1997 amphibole nomenclature (Leake et. al. 1997), and introduced as IMA 2003-066 later without any further investigation (Burke and Ferraris, 2003).

The name parvowinchite was discredited in the 2012 amphibole nomenclature, and it has been given the new root-name ghoseite.

Since the name "tirodite" has been used for both for cummingtonite- and ghoseite-group minerals, many of the locality entries for ferri-ghoseite will probably be cummingtonite-group minerals.
