Figure F82. Close-up photograph of a diagonal, planar, pyroxenite vein (Px) cutting harzburgite. The pyroxenite is undeformed and is cut by a subhorizontal gabbroic vein (Gb) (also undeformed) and a second vein that is internally deformed and offsets the pyroxenite vein with a reverse sense of shear (upper left corner of photo). S = the harzburgite crystal-plastic foliation plane (interval 209-1270D-3R-2, 10
