TEM data on the orthopyroxene and plagioclase grains. (a) BF STEM image of a region of the rim of orthopyroxene with arrow indicating the zone of partial amorphization. (b) DF STEM image of the amorphous rim on the plagioclase grain, indicated by the arrow. (c) HRTEM image of the highly variable depth and degree of amorphization within the orthopyroxene. (d) HRTEM image of the rim of complete amorphization showing uniform the thickness on the plagioclase.
