Overlap sections of the Rutgers and Somerset cores. The colors correspond approximately the colors of the mudstones. The black bars represent normally magnetized rock; the white bars represent reversely magnetized rock. Note that facies of lake highstand deposits tend to be deeper (more gray and black) and that stratigraphic units are thicker in Somerset compared to Rutgers. Modified from Schlische (2002) based on data in Olsen et al. (1996).
