Fig. 17. Wartlike myrmekite with tiny quartz vermicules (black) in plagioclase (white) extends into microcline (grid-twinned; dark gray). Plagioclase of the myrmekite is optically continuous with the quartz-free plagioclase (white). Microcline also has a serrate contact against the plagioclase (light gray; left side). Hornblende (light tan; bottom); biotite (red brown; right corner). Colored curved strand is a paper wood tissue in the thin section glue. Bryan Meadow granodiorite, east of Elbert Lake.
