Goethite, hematite, and lepidocrocite were mixed in varying proportions to obtain red, orange, and yellow paint. The combination of aragonite, gypsum, and halotrichite-pickeringite (an alum) formed both the white paint and also the base used to bind the other colors. This mineral assemblage is probably from a local hot-spring deposit. Not only is the paint composition a potential indicator of prehistoric interaction networks and an aid for rock-art classification, but pictograph paint may even prove significant as a cultural and/or temporal index in certain regions"--P.
