Chemical Th-U-total Pb isochron (CHIME) ages were determined with an electron microprobe analyzer on 14 to 24 monazite grains in three garnet-biotite gneisses collected from separate outcrops in the eastern part of the Sør Rondane Mountains, East Antarctica. On the basis of geologic and petrologic s...
