Figure F60. Digital photomicrograph of Sample 179-1105A-30R-2, 109-113 cm, shows even dispersion of grain sizes in a dynamically recrystallized fine-grained gneissic gabbroic rock. Note highly strained plagioclase (complex undulose extinction and subgrain structure) and well-developed foliation defined by the preferred dimensional orientation of both plagioclase and clinopyroxene. Foliation is oriented upper left to bottom right (cross-polarized light; field of view = 5.5 mm).
