Ekaterina A. Selivanova
Formula:
NaFe3+Ti4(Si2O7)2O4(H2O)4
formerly given as (Na,Ca)3(Ti,Fe)4[Si2O7)2O4(OH)3].7H2O; later redefined (Sokolova et al., 2022)
Colour:
Dark-orange
Lustre:
Vitreous
Hardness:
3
Specific Gravity:
3.15
Crystal System:
Triclinic
Name:
Named in honour of Dr. Ekaterina A. Selivanova (b. 1967, Apatity, Russia), mineralogist from the Kola Science Centre of the Russian Academy of Sciences, for her contribution to the mineralogy of alkaline complexes and the study of layered titanosilicates. She has coauthored descriptions of seventeen new mineral species (as of 2021).
New structure type. Chemically similar minerals include ivanyukite-Na, ivanyukite-Na-C, ivanyukite-Na-T, penkvilksite, and to some extent also tiettaite.

Found in drill cores from 100-130 m below the ground, coming from the Lovozero Eudialyte Complex.

The crystal structure of selivanovaite is closely related to those of murmanite-group minerals and consists of the HOH-layers with the composition [N2M5Si4O18(OH)3] (M = Ti, Nb, Fe and Mn, N = Na, K, Ca, Mn, Mg and Zr) connected by additional N-octahedra with H2O molecules between them.

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.
