Notes: Unit names are from Mahoney, Fitton, Wallace, et al., 2001: IA = ooze, IB = chalk, II = limestone, IIA = chert, IIIA = white limestone, IIIB = mottled gray and pinkish white limestone. CC = calcite, Q = quartz and/or opal, ill = illite. Mineral determinations are from Mahoney, Fitton, Wallace, et al., 2001. Numbers in parentheses adjacent to the analyses are one standard deviation; for example, 99.8 (3.0) = 99.8 ± 3.0 wt% and 0.29 (4) = 0.29 ± 0.04 wt%.
