Figure F55. Digital photomicrograph of Sample 179-1105A-12R-2 (Piece 5, 50-53 cm), shows igneous lamination (approximately horizontal in photo) defined by the preferred dimensional orientation of elongate clinopyroxene and tabular plagioclase. Note albite and Carlsberg growth twins in plagioclase with blunt ends, which most commonly terminate at grain edges (cross-polarized light; field of view = 5.5 m).
