Figure 5

FMS images from 985 to 1030 mbsf in Hole 1150B showing alternating beds of silty claystone and diatomaceous siltstone in about 10 m cycle with fine stratifications. The sedimentary cycles can be correlated to natural gamma ray well. See Figure 3 for explanation of FMS display. Note that Caliper 1 (N-S) shows a constant diameter of 25 cm throughout the section, whereas Caliper 2 (E-W) varies from 30 to 35 cm.
