UM1990-73-SiO:KMnNaZn
Invalid as an unnamed mineral
This page is currently not sponsored. Click here to sponsor this page.
Formula:
K(KNa0.5◻0.5)(Mn1.5Na0.5)Zn3[Si12O30]
NOTE: as this is not an IMA-approved species, the formula shown here is a charge-balanced derivation of the original given formula: (K,Na)2Zn3Mn1.5Si12O30 and is consistent with the original description; other site occupancy arrangements are possible. The formula suggested here ostensibly reduces to the end-member dusmatovite formula.
Colour:
colourless
Specific Gravity:
2.92 (Calculated)
Crystal System:
Hexagonal
Member of:
Said to be a possible K-analogue of shibkovite, which is not true as shibkovite is both K-dominant and also contains Ca. Rather, the suggested composition appears similar or potentially identical to dusmatovite.
Milarite-type structure.
Found within pegmatitic quartz boulders; forms fine-grained aggregates, up to 2 cm in diameter; associates: reedmergnerite, microcline, eudialyte.
