Formula:
(Na,K,Ca)2MnZrSi4O12 · 6H2O
Colour:
Blackish-brown
Somewhat similar to gaidonnayite. Chemically also somehow related to kapustinite and litvinskite.
Brusk-like acicular crystals, in cellular to spherulitic intergrowths.
Reported from sodalite syenite of Mt. Karnasurt, as a product of eudialyte alteration.
Possibly equal to UM1967-14-SiO:HMnNaZr, given as "M35", (Na,X)2(Zr,Mn3+)Si3(O,OH)9•nH2O, a potential "H,Mn-analogue" of gaidonnayite.
