doi:10.2204/iodp.proc.318.109.2011 Stratigraphic correlation and composite sectionMagnetic susceptibility, GRA density, and NGR data collected from cores from Holes U1361A and U1361B were used to construct a short composite section for Site U1361. The NGR and magnetic susceptibility measurements were primarily used for core to core correlation and to construct the composite section (Figs. F26, F27). The depth offsets that define the composite section for Site U1361 are given in Table T8. Two cores were recovered from Hole U1361B. Core 318-U1361B-1H is severely disturbed. Core 318-U1361B-2H overlaps with Cores 318-U1361A-1H and 2H and covers an interval that is not well represented in the upper, disturbed part of Core 318-U1261A-2H (Figs. F26, F27). Following construction of the composite depth section for Site U1361, a single spliced record was assembled from the aligned core intervals from the two holes (Fig. F27). The composite data show that the cores from Site U1361 provide a continuous sequence from the seafloor to ~19.3 meters composite depth (bottom of Core 318-U1361A-2H). Below this depth, Cores 318-U1361A-3H through 41X were appended to the record (Figs. F26, F27; Table T9). The Site U1361 splice can be used as a guide to sample the sedimentary sequence for the uppermost part of the site. |
