Figure F4. Lithostratigraphic column for Site 1101 including percent biogenic component compiled from smear-slide data and magnetic susceptibility. Unit I consists of alternating packets of massive and laminated clayey silt. Unit II has 19 foraminifer-bearing beds that occur cyclically and coincide with lows in the magnetic susceptibility curve (see Fig. F8). Unit III is characterized by low biogenic content in its upper part and relatively low magnetic susceptibility. A sharp peak in magnetic susceptibility coincides with a turbidite near the base of the hole.
