Fig. 3. Albite-twinned plagioclase (white, top) with cataclastically broken border. Veins of microcline (gray-black) penetrate the plagioclase along fractures. Remnants of the original plagioclase crystal extend in a stringer of broken grains from the main crystal through the microcline, and some of these grains have converted to myrmekite. A plagioclase inclusion (cream) in the microcline is bordered by myrmekite.
