Figure F20. A. Smoothed GRA bulk density for Sites 1168, 1170, 1171, and 1172 vs. depth. Data from multiple holes were combined for Sites 1170, 1171, 1172 to produce a complete profile. Stratigraphic boundary depths were taken from "Biostratigraphy" in the individual site chapters. B. Smoothed MST magnetic susceptibility data for Sites 1168, 1170, 1171, and 1172 vs. depth. Data from multiple holes were combined for Sites 1170, 1171, 1172 to produce a complete profile. Stratigraphic boundary depths were taken from biostratigraphy section in the individual site chapters.
