Figure F39. A–C. Layer of orthopyroxene-bearing olivine gabbro within an anorthositic gabbro (Sample 345-U1415P-14R-1, 16–25 cm [Piece 3]). (A) Dry image; red box (tick mark shows upward direction) indicates location of image in B. (B) Lower contact (dashed red line) between orthopyroxene-bearing olivine gabbro and anorthositic gabbro. Red box indicates location of image in C. (C) Relatively large cluster of intergrown and deformed plagioclase crystals in olivine gabbro. D. Complex plagioclase crystal texture that shows subgrain development that may have captured partial annealing (Sample 345-U1415P-11R-1, 43–44 cm [Piece 6]). B, C, and D are under crossed polars.
