About CalciosamarskiteHide

Specific Gravity:
4.48 - 4.74
Crystal System:
In allusion to the composition, containing calcium, and its relationshp to samarskite.
Samarskite Group.

The empirical formula based on Hanson et. al. (1999) is (Ca0.31Y0.17Fe2+0.26U0.19Na0.08REE0.23)1.24(Nb0.79Ta0.07Ti0.04)0.90O4; all species are required for charge balance, and iron is assumed to be ferrous, also to maintain charge balance. The ideal formula, as given above, cannot have any divalent cations in the A position in order to maintain charge neutrality.

Classification of CalciosamarskiteHide

Approved, 'Grandfathered' (first described prior to 1959)

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
D : Metal: Oxygen = 1:2 and similar
B : With medium-sized cations; chains of edge-sharing octahedra
