BSE images of monazite grains from the VP7r orthogneiss. Circles indicate the location of the LA-ICPMS pits (7 µm diameter) and their corresponding 206Pb/238U dates (2σ level). Only consistent dates in both the 208Pb/232Th–206Pb/238U and 206Pb/238U–207Pb/235U systems are shown; dashed circles indicate the location of the other spot analyses. (a), (b) and (c) Monazite I grains in plagioclase pseudomorphs (ps Pl) with reaction microcoronas composed of apatite (Ap), zoisite (Zo) and monazite II (Mnz II; the small crystals could not be analysed).
