Figure F59. Digital photomicrograph of Sample 179-1105A-4R-4, 57-62 cm, shows recrystallization of plagioclase neoblasts along subgrain boundaries in large plagioclase at the initial stages of neoblast formation in a coarse-grained gabbro. Note plagioclase deformation twins and curvature into the recrystallization zone (cross-polarized light; field of view = 5.5 mm).
