| 英文摘要 | a group of 2,6,10,15,19-pentamethylicosenes (pmi delta) containing 1-5 unsaturated double bonds has been identified in the sea floor sediments from the gulf of mexico at the green canyon 238 site. these pmi delta compounds are distributed between nc(22) and nc(24) on the mass chromatogram of aliphatic fraction. their delta(13)c values are very much depleted in (13)c and in the range of -86.7% to -115.5%, whereas the delta(13)c values of companion n-alkanes range from -28.4% to -34.6%. these unsaturated pmi delta compounds are typical biomarkers derived from the anaerobic oxidation of methane mediated by methane-oxidizing archaeal bacteria and indicative of the gas seeps or even the occurrence of gas hydrates in the deep sea sediments. |
