(K,Ba)3(Fe,V,Ce)3Ti14O32
a single analysis corresponds to K2V2Ti6O16
Colour:
opaque in thin section
Hardness:
6
Chemically related to jeppeite and priderite, but the composition is unique if one consider the diadochy substitutions.
Reported as "Unnamed K-V-Ba titanate"; forms anhedral grains (homogenous, but with intra-grain chemical variation), and stellate clusters (at least 0.1 mm in size) of prismatic crystals, in kimberlitic groundmass.
