Colour:

Colorless or white

Specific Gravity:

3.402 (Calculated)

Name:

Named in honor of Gaius Plinius Secundus (AD 23/24 – 79), called Pliny the Elder. He was a Roman author and naturalist, and a naval and army commander. He wrote Naturalis Historia ("Natural History"), which became a model for encyclopedias.

Pekov et al. (2022) report the discovery of a new apatite-group mineral, pliniusite, ideally Ca5(VO4)3F, the second vanadate mineral of the apatite supergroup, in fumarole exhalations at the Tolbachik volcano (Kamchatka, Russia) and in a pyrometamorphic rock of the Hatrurim Complex (Israel).

Pliniusite, fluorapatite Ca5(PO4)3F, and svabite Ca5(AsO4)3F form an almost continuous ternary solid-solution system with wide variations of T5+ = P, As, and V. The combination of high temperature, low pressure, and high oxidizing potential is favorable for the incorporation of V5+ into calcium apatite-type compounds and in general for the formation of fluorovanadates.
