Abstract This study presents monazite and rutile U–Pb and hornblende and biotite 40 Ar/ 39 Ar geochronological data for high-grade rocks of the eastern Grenville-aged Rayner orogen at Mount Brown in order to analyse the extent and degree of Pan-African-aged reworking. Monazite from paragneiss yields...
