Name:
in allusion to calcium content and relation to murmanite
The Na-Ca ordered analogue of murmanite. Chemically related to, e.g., kolskyite.
One of many species based on sheet-structured HOH heteropolyhedral-octahedral blocks. It has three sheets of the following content:
- the O sheet: NaO6 and TiO6 octahedra forming alternating chains
- the H sheets: disilicate groups + TiO6 octahedra + CaO8 polyhedra
Water is located in 2 sites within the interlayer space.

Based on recorded range of RI values above.
Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

Type Occurrence of Calciomurmanite
Co-Type Localities:
General Appearance of Type Material:
lamellar crystals, up to 0.1 × 0.4 × 0.6 cm, may form fan-shaped aggregates, up to 3.5 cm
Place of Conservation of Type Material:
Type material is deposited in the collections of the Fersman Mineralogical Museum, Russian Academy of Sciences, Moscow, Russia, catalogue number ST4994; cotype material is deposited in the collections of the Bel’kov Museum of Geology and Mineralogy, Kola
Geological Setting of Type Material:
hydrothermal in hyperagpaitic (peralkaline) rocks, resulting from low-temperature alteration (hydration + cation exchange) of a high-temperature phosphate-bearing titanosilicate precursor (possibly lomonosovite and/or beta-lomonosovite); associated minerals are those at the holotype locality (Flora Mt.)
