NICKEL SULFIDES IN PYROXENITE FROM LANGHOVDE, LUTZOW-HOLM BAY, EAST ANTARCTICA
Nickel sulfides occur as minute grains in a pyroxenite xenolith enclosed in a garnet-biotite gneiss from Langhovde, Lutzow-Holm Bay, East Antarctica. They include pentlandite, millerite, violarite and Ni-bearing pyrite in the decreasing order of appearance. The Ni/Fe ratio in pentlandite is high and...
