Figure F81. Close-up photographs illustrating the complex nature of gabbroic and pyroxenititic veins that cut peridotite in Hole 1270D. Some gabbroic veins, at the top and bottom of the piece, are near parallel to the foliation in harzburgite, but there are also crosscutting veins at a high angle to the foliation in the center of the piece. The veins that are near parallel to the harzburgite foliation appear to have localized deformation within the piece (interval 209-1270D-3R-1 [Piece 8, 53–76 cm]). A. Cut face. B, C. Two outer edges of the precut core.
