Acidic gneiss (orthopyroxene-mesoperthite-quartz gneiss), being one of the main representative metamorphic rocks, gave an age of 2516±274 Ma with an initial ^<143>Nd/^<144>Nd ratio of 0.50914±0.00021. εNd values normalized to 2516 Ma for individual acidic gneiss range from -3.7 to -7.0. This Sm-Nd whole-rock isochron age indicates a major period of equilibration of the isotopic system on a whole-rock scale at 2516±274 Ma.}, pages = {115--121}, title = {PRELIMINARY RESULT FOR THE Sm-Nd WHOLE-ROCK AGE OF THE METAMORPHIC ROCKS FROM MOUNT PARDOE IN THE NAPIER COMPLEX, EAST ANTARCTICA}, volume = {7}, year = {1994} }
