Fig. 4. Representative photo-micrographs of the schists, gneisses, and granodiorite samples of the Cooma metamorphic complex, collected from the outcrops plotted on Fig. 2. All photo-micrographs are at the same scale (20× or 1 mm = 40 μm) and the rocks are as viewed under crossed polars.

(b) RMC-4 andalusite zone schist: quartz, biotite (with halos), muscovite
(c) RMC-5 K-feldspar zone gneiss: quartz, K-feldspar, biotite (with halos), muscovite
(d) RMC-6 K-feldspar zone gneiss: quartz, K-feldspar, biotite (with halos), muscovite
(e) RMC-7 migmatite zone gneiss: quartz, plagioclase, K-feldspar, biotite (with halos) muscovite
(f) RLG-2 Cooma granodiorite: quartz, plagioclase, K-feldspar, biotite (with halos), zircon
(g) RGC-1 Cooma granodiorite: quartz, plagioclase, K-feldspar, biotite (with halos), zircon, muscovite
