Coulsonite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Fe2+V3+2O4
Hardness:
4½ - 5
Member of:
Name:
After Dr. Arthur Lennox Coulson, Geological Survey of India.
Initially described from Bihar, India in 1936 as vanado-magnetite, renamed the following year as coulsonite (these specimens contain up to 4.84% vanadium). Species was redefined in 1962 on Nevada material.
