Corundum from
Norra Kärr, Gränna, Jönköping, Jönköping County, Sweden


Locality type:Complex
Classification
Species:Corundum
Formula:Al2O3
Comments:Staffan Karlsson reported corundum in 1997. Later XRD analysis by the same author determined that the mineral was in fact andradite.

Adamson (1944, p.221) only mentions normative corundum based on the whole-rock chemical composition of a fenite sample. He has in fact not observed corundum, which is also stated in a letter from 1988.
