About Manganiandrosite-(La)Hide

06097420016454501954739.jpg
Andros Island, Greece
Formula:
(Mn2+La)(Mn3+AlMn2+)O[Si2O7][SiO4](OH)
Colour:
Brown-red
Lustre:
Vitreous
Specific Gravity:
>4.03
Crystal System:
Monoclinic
Name:
Originally named androsite-(La) in 1996 after its discovery locality on Andros Island, Greece. It was renamed by the Epidotes Subcommittee of the CNMMN in 2006. The prefix indicates a predominance of Mn3+ at the M1 site. The suffix/modifier indicates the dominant cation at the A2 site, which for the allanite subgroup is always a REE and in this case is lanthanum.
A member of the Allanite Subgroup of the Epidote Group.
Manganiakasakaite-(La)-Manganiandrosite-(La) Series.
