Figure F17. X-ray diffractogram traces of samples from lithologic Unit II. Ill = illite; Clay = nonbasal clay mineral reflection; Qz = quartz; Fsp = feldspar; Hal = halite; Paly = palygorskite; and Z = zeolite. Halite is from seawater. All samples are from monotonous background sediment. Note that the XRD pattern of background sediment from Core 185-1149A-14H is very similar to that of Unit I clays (Fig. F13). Note that individual diffractograms are offset by 500 cps for clarity.
