^<40>Ar-^<39>Ar AND K-Ar AGES FOR IGNEOUS AND METAMORPHIC ROCKS FROM THE SØR RONDANE MOUNTAINS, EAST ANTARCTICA
Eight ^<40>Ar-^<39>Ar and six K-Ar ages were determined for igneous and metamorphic rocks collected from the Sør Rondane Mountains, East Antarctica. Biotites from granite and syenite show ^<40>Ar-^<39>Ar ages of about 500 Ma, which are similar to the reported Rb-Sr age. K-Ar...
