Fig. 9. Cataclastically-broken felsic diorite, showing fractured plagioclase crystals (dark gray, light gray; bottom and left) being replaced by microcline (white; center and upper left). Hornblende (brown; upper right) has very minor quartz sieve texture. Unfractured microcline penetrates along fractures (replacing the plagioclase) and surrounds island remnants of plagioclase that are optically continuous with large unreplaced portions of the plagioclase.
