About Manganbelyankinite
Dmitry S. Belyankin
Formula:
Mn2+(Ti,Nb)5O12 · 9H2O
Mn may be replaced by minor Ca.
Colour:
Brownish black
Lustre:
Resinous
Hardness:
2 - 2½
Specific Gravity:

Name:
Named for being the manganese analogue of belyankinite. The root name belyankinite honors Dmitry Stepanovich Belyankin (11 (23) August 1876, Lamanich, Vologda Province, Russian empire - 20 June 1953, Moscow, Russia), prominent Russian mineralogist and petrographer. He headed, at different times, the Petrographic Institute, the Institute of Geological Sciences, and the Mineralogical Museum at the USSR Academy of Sciences. Also the Kola branch of the USSR Academy of Sciences (Kirovsk). He is considered a founder of technical petrography.
