“…The specific gravity of most petroleum oils lies between 0.735 and 0.950 (GRuSE 1928). Several general descriptions of the nature of petroleum and its physical characteristics have been written (BRANNT 1895, GRUSE 1928, PURDY 1958, SPEERS and WHITEHEAD 1969.…”

“…Their occurrence in ancient sediments and petroleums (Johns et al, 1966;Speers and Whitehead, 1969) and their formation in simulated maturation experiments (Ishiwatari and Fukushima, 1979;Rubinstein and Strausz, 1979) suggest that their presence in Section 491-1-5 reflects input from thermally mature sources.…”

We investigated the solvent-extractable hydrocarbons, ketones, alcohols, and carboxylic acids of two Quaternary sediments from the Middle America Trench (Sections 487-2-3 and 491-1-5). These lipids are derived from a mixed input of autochthonous and allochthonous materials, with minor contributions from thermally mature sources. Their compositions are typical of those of immature Quaternary marine sediments, and their lipid distributions show many similarities to those of Japan Trench sediments. INTRODUCTIONThe solvent-extractable lipids of two Quaternary sediments (Sections 487-2-3 and 491-1-5) from the oceanic plate and central slope of the Middle America Trench were investigated by gas chromatography and computerized gas chromatography-mass spectrometry. The sections were chosen to permit the comparison of environments on either side of the trench. This preliminary report describes the lipid compositions of these two samples and interprets them in terms of their input sources, conditions of deposition, and extent of diagenesis. We also make a brief comparison of their lipid distributions with those of Quaternary sediments from the Japan Trench. Table 1 summarizes the lithological characteristics of the samples and includes their weights. Organic carbon determinations were not made for these samples, but the values of adjacent sections are given (site chapters, this volume).

“…Where both pristane and phytane are present in these sediments, pristane is always more abundant (Table 1). The dominance of pristane over phytane is not unexpected because in recent marine sediments phytane is usually present in much smaller amounts than pristane (Blumer and Snyder, 1965), while both pristane and phytane are common in petroleum (Speers and Whitehead, 1969).…”
