Composite for five holes of bed-by-bed sections from
cores (left column), bed-by-bed sections from the
interpretation of FMS images and geophysical logs
(middle column), conventional gamma-ray (SGR, solid
lines), and velocity logs (right column). Bold arrows
point to boundaries of stratigraphic intervals
specified in large typeface. Locations of FMS images
in Figures 48 are marked. A.
Hole 931B (FMS depth based on logging pass 2). B.
Hole 935A (FMS depth based on pass 2). C.
Hole 936A (FMS depth based on logging pass
2). D. Hole 944A (FMS depth based on
logging pass 2). E. Hole 946A (FMS
depth based on logging pass 1).
Longitudinal composite of seismic reflection profiles
from the middle to the lower fan along the Amazon
Channel showing distribution of acoustic units. See
Figure 1B for location of profiles. The left end of
the left-hand profile is just downfan of Site 930.
Here, the transparent levee ~0.30.4 s below the
fan surface is the Red Channel-levee System of the
Middle Levee Complex. The amalgamated HARP of the
Upper Levee Complex lies between the Red levee and
the transparent upper levees at the fan surface. The
individual HARPs in this composite unit, each
associated with a different channel-levee system,
merge downfan; individual channel-levee systems
cannot be mapped confidently toward the lower portion
of the fan (right seismic profile). Site 946 is
located at the left end of the right-hand seismic
profile. Here, the Stage 5 highstand carbonate is
represented by a continuous reflection ~0.15 s below
the surface of the fan (Fig. 13A).
