Nature, origin, and petroleum source potential of organic matter at DSDP Leg 56-57 Holes@en

As part of a continuing program of organic-geochemistry studies of sediments recovered by the Deep Sea Drilling Project, we have analyzed the types, amounts, and thermal-alteration indices of organic matter in samples collected from the landward wall of the Japan Trench on Legs 56 and 57. The samples were canned aboard ship, enabling us to measure also their gas contents. In addition, we analyzed the heavy C15+ hydrocarbons, NSO compounds, and asphaltenes extracted from selected samples. […]

作为深海钻探计划（Deep Sea Drilling Project）沉积物有机地球化学长期研究项目的组成部分，我们针对第56、57航次自日本海沟陆侧壁采集的样品，分析了其中有机质的类型、含量与热蚀变指数。所有样品均在船上完成罐装封存，这使得我们还可测定样品的气体含量。此外，我们对从选定样品中提取的C15+重烃、NSO化合物以及沥青质进行了分析。[…]
