Figure F12. Diagram showing the variation in various sedimentary components with depth in the sequence at Sites 1039 and 1253 as identified in smear slide analyses during Legs 205 and 170. Plots show only where the component was considered to be abundant (>30%). Sandy beds are only present as minor lithologies and are restricted to lithostratigraphic Units U1 and U2. Diatoms are present throughout the core but are most common in lithostratigraphic Unit U1; conversely, nannofossil abundance is higher in lithostratigraphic Subunits U3A-U3C. Volcanic ash is present throughout the section.
