Figure F49. Interval 192-1185B-16R-1, 22-37 cm, showing pervasively altered basalt grading in color from dark yellow-brown (top) to dark brown toward a pillow interior. The sample contains several thin horizontal calcite veins connected by a larger vertical calcite vein. The abundance of crosscutting veins is higher in the more heavily altered dark yellow-brown portion.
