Figure F13. Spliced records of gamma ray attenuation (GRA) bulk density, magnetic susceptibility, and the color reflectance parameter (L*) shown for the composite section of Site 1220. Lithology changes are clearly visible. High GRA density values centered on 100, 110, and 195 mcd are instrumental artifacts.
