Figure F54. Digital photomicrograph of Sample 179-1105A-12R-2 (Piece 5, 50-53 cm), shows an igneous lamination defined by the preferred dimensional orientation of elongate clinopyroxene and tabular plagioclase. Lamination is oriented from upper left to lower right corner. Also note core-rim zoning in larger plagioclase (near extinction) and magmatic twins in clinopyroxene (upper left). Also note some plagioclase crystals contain deformation twins, which generally effect most igneous textures in cores from Hole 1105A (cross-polarized light; field of view = 5.5 mm).
