Macedonite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
PbTiO3
System:
Tetragonal
Colour:
Black with weak brownish ...
Lustre:
Vitreous
Hardness:
5½ - 6
Name:
After the type locality at Crni Kamen, Macedonia. First described by Radusinović and Markov (1971)
A rare accessory mineral in microcline-quartz syenite pegmatite veins and as inclusions in oxide phases in a metamorphosed Fe-Mn ore body.

Macedonite is an oxide single perovskite with second order Jahn-Teller distortions. The Macedonite from Crni Kamen is the only natural perovskite mineral known to contain significant amounts of Bi2O3 (2.2 wt.%) (Mitchell et al. 2016).
