Environments
Carlsbergite occurs as minute platelets and grain boundary precipitates in
kamacite and troilite, and as
similar grains ringing daubréelite in
iron meteorites. Associated minerals include
kamacite, taenite,
daubréelite, troilite and
sphalerite.
(HOM).
Localities
At the type locality, the Cape York meteorite, Cap York, Avannaata, Greenland, carlsbergite occurs as
oriented platelets in kamacite, typically 30 x 5 x 2 microns3,
and as grain-boundary precipitates a few microns in diameter. Also ringing
daubréelite or in association with
sphalerite
(Mindat).
