Fig. 14. Left third. Microcline (dark gray) surrounding (a) myrmekite, (b) quartz-bleb clusters in plagioclase in which the boundary between the plagioclase and the microcline is not well defined, and (c) quartz-bleb clusters in the microcline. Quartz (cream, yellow). Middle third. Grid-twinned microcline (light gray) with quartz-bleb clusters in plagioclase with fuzzy borders against the microcline (upper half, near cotton tissue thread). Right third. Microcline (black) with a myrmekite projection (left side) in which the tiny quartz vermicules are not yet well developed by recrystallization. Quartz-bleb clusters with tiny quartz blebs (white) occur in the microcline.
