Figure F32. Tmax values generated from Rock-Eval pyrolysis analyses of organic matter for Site 1171. The high variability of values above ~460 mbsf is likely caused by very low TOC values in these samples. Below 460 mbsf, Tmax values are indicative of immature organic matter relative to oil generation and the presence of bitumen, although values approach the "oil window" (dashed vertical lines) at the base of the core. Lithostratigraphic and preliminary biostratigraphic units are indicated on the right side of the diagram.
