Fig. 9. Border of large orthoclase megacryst (light gray) near its corner, showing granulated groundmass minerals (left side). Quartz (white); plagioclase (light gray); biotite (brown). Tiny plagioclase inclusions show parallel alignment but some are slightly tilted. Some have an outer, sodic rim. Note that orthoclase grows around granulated groundmass minerals along the edge of the megacryst.
