Figure F60. Color close-up photograph of interval 183-1141A-24R-1 (Piece 2H, 85-101 cm). Subvertical quartz + minor calcite vein with multiple alteration halos. Starting from the vein margin, these halos are dark green, light green, dark red, and light red, grading into dark red-gray basalt (Unit 6). The intensity of alteration in these halos decreases with distance from the vein. This complex pattern is crosscut by late calcite vein. Vesicles with colloform textures are also visible.
