sample_remark (plg-kspar-hbl-mag-ap-bi gneiss) Howard et al 2011 (AJES): plagioclase-k-feldspar-hornblende-magnetite-apatite-biotite gneiss. Late muscovite seritisation occurs in the matrix, and chlorite overgrows hornblende. Grains of potassium feldspar, plagioclase and hornblende are approximately 500 mm in size. Fine-grained matrix minerals including magnetite, apatite and biotite are roughly equigranular and are approximately 250 mm in size. Hornblende forms in elongate clusters of grains that define the foliation.
