The results of a preliminary organic analysis conducted on sediment samples from Sites 677 and 678, ODP Leg 111, indicate that the lipids are derived mainly from marine organisms, with bacterially-derived lipids. Terrestrial higher plant wax residues exist only in trace amounts. Diagenesis of organic matter by thermal stress is not extensive at either site.
