About Nataliakulikite
Formula:
Ca4Ti2(Fe3+,Fe2+)(Si,Fe3+,Al)O11
Colour:
Brown
Lustre:
Sub-Metallic
Hardness:
5½ - 6
Specific Gravity:
4.006 (Calculated)
Crystal System:
Orthorhombic
Name:
For Natalia Artyemovna Kulik (b. 1933) from Novosibirsk, Russia, a well-known Russian mineralogist, a reputed expert in mineralogical descriptions of granitic pegmatites, minerals of radioactive and rare-earth elements and archaeometry.
Somewhat related to shulamitite and sharyginite. Quite a unique stoichiometry as for natural perovskite-structured material. Previously this mineral was described in the Hatrurim larnite rocks as a Si-Fe2+-rich natural analog of synthetic Ca4Ti2Fe3+2O11
