Figure F57. Subvertical anastomosing amphibole vein network in Sample 176-735B-92R-1 (Piece 3A, 10-15 cm). The vein network cuts strongly developed crystal-plastic deformation. Although this style of vein network is relatively common in the upper sections of core recovered during Leg 118, it is rare in gabbroic rocks recovered from below 500 mbsf.
