Figure F65. Close-up photographs of examples of alteration veins and their crosscutting relationships in gabbros from Hole 1275D. A. Green amphibole-chlorite vein crosscut by a brown clay-carbonate vein (interval 209-1275D-24R-1, 98–114 cm). B. Brown clay, Fe oxyhydroxide-carbonate vein cutting a gabbro (interval 209-1275D-25R-3, 22–33 cm). C. Green amphibole-chlorite vein crosscutting earlier felsic veins in a gabbro (interval 209-1275D-27R-1, 140
