Fig. 7. Felsic diorite, showing deformed (bent) Carlsbad- and albite-twinned plagioclase crystal (light and dark gray). Other large plagioclase crystals (left side have cataclastically broken grain boundaries. Hornblende crystal (brown, bottom) is adjacent to tiny grains of quartz (clear white). Microcline (light gray) is in earliest stages of replacement of deformed plagioclase and occurs as a few tiny irregular blebs just above the hornblende and quartz in the bottom part of the deformed plagioclase. Microcline is much less than 1 vol. % of the rock. (Photo magnification is 52.5x)
