Figure F61. Styles of magmatic layering and foliation, Unit II. A. Centimeter-scale modal layering with an olivine-bearing gabbronorite layer (Interval 30; 2.5–6.5 cm) between a troctolite layer (Interval 29; 0.5–2.5 cm) at the top and a second thin troctolite layer (Interval 31; 6.5–9 cm) in turn overlying an olivine-bearing gabbro layer (Interval 32;, 9–63 cm) at the bottom (Sample 345-U1415J-5R-2A, 2.0–17.5 cm [Piece 1]). Also shown is olivine-plagioclase magmatic foliation. B. Centimeter-scale modal layering consisting of a 2 cm thick olivine-bearing gabbro layer (Interval 42; 111–116 cm) within a clinopyroxene oikocryst-bearing troctolite layer (interval 345-U1415J-8R-2, 105.5–121.0 cm [Piece 9]). Also shown is olivine-plagioclase magmatic foliation. C. Olivine-plagioclase magmatic foliation anastomosing around large (up to 2 cm diameter) clinopyroxene oikocrysts in an oikocryst-bearing troctolite (interval 345-U1415J-8R-3, 76.0–91.5 cm [Piece 9]).
