Formula:
(V,Cr)2Ti2O7
Chemically similar to berdesinskiite, schreyerite, and 'Unnamed (Ti-V oxide)'. Co-described with UM2002-05-O:CrTiV, UM2002-06-O:CrTiV, UM1996-17-O:CrFeNbTiV, and 'Unnamed (Vanadium Titanium Oxide 2)'.
The V analogue of UM2002-05-O:CrTiV with which it forms a series.
As inclusions, up to 10μm in diameter, with berdesinskiite, schreyerite, and olkhonskite, all included in rutile (Koneva, 2002).
Note: not found in Smith & Nickel (2007) "Valid Unnamed Minerals" IMA list.
EPMA data [wt.%]:
TiO2 52.15
Cr2O3 16.40
V2O3 29.32
FeO 0.52
Al2O3 0.68
total 99.07
This corresponds to (V1.22Cr0.67Al0.04Fe0.02)Σ1.95Ti2.04O7.
