Figure F27. The Tmax values generated from Rock-Eval pyrolysis analyses of organic matter for Site 1170. The high variability of values above ~460 mbsf is likely caused by the very low TOC values in these samples. Below 460 mbsf, the Tmax values are indicative of immature organic matter relative to oil generation, although values approach the "oil window" (vertical dotted lines) at the base of the core.
