PETROLOGY OF DOLOMITIC MARBLES FROM KASUMI ROCK, PRINCE OLAV COAST, EAST ANTARCTICA
Dolomitic marble containing primary chlorite, Zn-rich spinel and F-rich clinohumite occurs in the upper amphibolite-facies Kasumi Rock, Prince Olav Coast, East Antarctica. Minerals in the chlorite-bearing dolomitic marble along with another dolomitic marble from the Kasumi Rock were analyzed with an...
