Figure F104. Hole 1109D statically normalized FMS image shows the highly resistive, sandy base of a turbidite unit at 161.5 mbsf that grades upward to more conductive clays at 157 mbsf. The well-defined base of this unit correlates with the lithostratigraphic Unit II/III boundary (see "Lithostratigraphy" in the "Site 1109" chapter). Vertical scale = 1:40.
