Backscattered electron images (BSE) of monazite in mylonitic garnet gneisses and garnet-bearing micaschists. Numbers are EMP chemical ages from monazite, calculated as weighted means with 2 sigma error (see text) or from single analyses. Locations of microprobe analyses are marked. a Large Ordovician monazite grain in low-strain domain near large garnet porphyroblast in mylonitic garnet gneiss. b Large Ordovician monazite enclosed in garnet porphyroblast in mylonitic garnet gneiss. c Large monazite grain in mylonitic garnet gneiss. Some analyses with Variscan ages reveal partial recrystallization of the monazite. d Reaction site in mylonitic garnet gneiss with Variscan monazite satellites around central apatite. e Ordovician monazite in mylonitic high strain domain in garnet gneiss. f Homogeneous Variscan monazite elongated parallel to the foliation in a micaschist. g Variscan monazite enclosed in micaschist garnet. Monazite may have crystallized along cracks subsequent to garnet. h Homogeneous Variscan monazite with enclosed apatite. i Variscan monazite with partial decomposition along the margin. Decomposed parts give random post-Variscan ages
