Name:
First described by Gerasimovskiy and Kazakova (1962) from two pegmatites on the left and right banks of the Tyul'bnyunuai River, Lovozero massif, Kola, Russia. It was named betalomonosovite for its similarity to lomonosovite. Around the same time the name metalomonosovite was also used because the mineral was assumed to contain sodium metaphosphate. The status has been much discussed because of difficulties obtaining valid results on structure and chemical analyses. The poor quality of the crystals was related to an extensive cation and anion disorder present in the structure, including H2O (Sokolova et al. 2015). As a result it was discredited by IMA in 2013 (removed from the IMA list). Later Sokolova et al. (2015) succeeded in refining the structure. Based on their work, betalomonosovite was reapproved by IMA in 2015 (IMA 14-J) (Sokolova et al. 2015). It was renamed to paralomonosovite in 2022 by the IMA.
Samples from Pyalkimporr Mountain, Lovozero Massif were used in the study of Sokolova et al. 2015).

Isostructural with:
A Na-poor OH-bearing analogue of lomonosovite.
Paralomonosovite is a Group-IV TS-block mineral (Ti + Mg + Mn = 4 apfu). The crystal structure of paralomonosovite is an alternation of TS and I blocks of the composition Na4Ti4(Si2O7)2O2(OF) and Na2D4[PO3(OH)][PO2(OH)2], respectively (Sokolova et al. 2015).

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.
