Figure F38. Plot of downhole distribution of main alteration colors representing overall color of each lithologic unit (units defined by the igneous petrology group). Circles are located at center depth for each unit. The color of both clasts and cement is reported for some units, especially those where volcanic clasts are surrounded by a volcanic matrix. Gray shading represents sedimentary units, pink and green shading represent basalts that were altered under oxidized and reduced conditions, respectively.
