Diversilite-(Ce)
Diversilite-(Ce) is an IMA-recognized mineral species in the silicate class, with the chemical formula Na₂Ba₆Ce₂Fe²⁺Ti₃Si₁₂O₃₆(OH)₁₀·nH₂O.
It crystallizes in the hexagonal crystal system (space group R-3).
Key properties: Mohs hardness 5; specific gravity 3.68; White streak; Vitreous luster; optically uniaxial.
IMA symbol Dvs-Ce, IMA status: approved, named in 2002.
Found in a complex granitic pegmatite.
It is found associated with Nepheline, sodalite, K-feldspar, natrolite, pectolite, aegirine, shcherbakovite, lamprophyllite, magnesium astrophyllite, delindeite, wadeite, umbite.
The name comes from the Latin diversus for “heterogeneous” and SILIcate, alluding to the compositional diversity, structural complexity and dominant anionic and rare earth compositions of the mineral.
