Finding of vanadium-bearing garnet from the Sor Rondane Mountains, East Antarctica
Vanadium-bearing green garnets have been found in the Menipa mountain mass, central part of the Sor Rondane Mountains, East Antarctica. These garnets are the main constituent minerals of granulite-facies metamorphosed graphite-bearing calcareous metapelite. They show three types of mode of occurrenc...
