Fig. 6. Felsic diorite, showing slight cataclastic texture. Hornblende (brown and green) has a sieve texture of tiny islands of microcline (gray) and quartz (white, gray, and cream). Albite-twinned plagioclase (white and gray) is in upper left. Microcline is less than 1 vol. % of the rock. (Photo magnification is 52.5x)
