引言直到1968年,JOIDES 开创深海钻井和取芯方案以前,有机地球化学的研究局限于埋藏深度小于50米深的未成岩的海洋沉积物样品。本工作叙述了五个钻井中的十五块岩样的分析。最深样品的取芯是534米(钻孔3)属中新世;年代最老的样品是从钻孔6(153米)取得的,属始新世。本研究我们试图去分析烃类。脂肪酸,色素(绿包素和卟啉)和氨基酸。对全部沉积样品中的有机碳和某些可抽提的以及不可抽提的残渣(例如:腐殖酸和干酪根)进行了 C~(13)/C~(12)比值的测定。
INTRODUCTION Until 1918, JOIDES pioneered deepwater drilling and coring programs, organic geochemical studies were limited to immature diatomized marine sediment samples buried less than 50 meters deep. This work describes the analysis of fifteen of the five drilling wells. The deepest sample coring is 534 meters (borehole 3) belongs to the Miocene; the oldest sample is obtained from the borehole 6 (153 meters), is Eocene. In this study, we try to analyze hydrocarbons. Fatty acids, pigments (greening and porphyrin), and amino acids. The C 13 / C 12 ratio of organic carbon and some extractable and non-extractable residues (such as humic acid and kerogen) in all the sedimentary samples was determined.
