Labuntsovite-Mn

This page is currently not sponsored. Click here to sponsor this page.
Russian mineralogist Aleksander Nikolaevich Labuntsov.
Formula:
Na4K4(Ba,K)2Mn2+(Ti,Nb)8(Si4O12)4(O,OH)8 · 10-12H2O
System:
Monoclinic
Hardness:
6
Name:
Named after the Russian mineralogists Aleksander Nikolaevich Labuntsov and Ekaterina Eutiikkieva Labuntsov-Kostyleva.
Labuntsovite Group.

This is the original labuntsovite. It is now designated labuntsovite-Mn for the dominance of manganese among the divalent cations.
