Carlsbergite
Chromium nitride mineral found in meteorites
(repeating unit)H-M symbol: (4/m 3 2/m)
Carlsbergite is a nitride mineral that has the chemical formula CrN,[2] or chromium nitride.
It is named after the Carlsberg Foundation which backed the recovery of the Agpalilik fragment of the Cape York meteorite in which the mineral was first described.[2]
It occurs in meteorites along the grain boundaries of kamacite (nickel-rich native iron) or troilite (FeS: iron sulfide) in the form of tiny plates.[2] It occurs associated with kamacite, taenite, daubreelite, troilite and sphalerite, (Zn,Fe)S.[3]
