Initial Characterization of Organic Matter in Cretaceous- Paleogene Sedimentary Rocks, Cape Roberts, Antarctica

该奖项支持了预计在Cape Roberts项目（CRP）期间回收的白垩纪-古近系沉积岩的有机地球化学表征。CRP计划于1995年和1996年在罗斯海的一个快速冰钻井平台上钻4个500米的洞。将对回收的岩心进行描述、整理和取样，用于科学研究。CRP有可能回答关于南极西部裂谷系统的历史、白垩纪和古近纪南极洲大陆冰盖的发育、生物群对气候恶化和航道发展的响应等重要问题。有机地球化学测量与这些问题有关，因此包括在岩心初步表征研究中。这里支持的工作包括全岩碳酸盐碳、总碳、总氮和总硫的测量，选定样品中干酪根元素组成的分析，以及选定样品中溶剂可溶性有机质的气相色谱分析。这些数据将在麦克默多站的克雷瑞科学与工程中心（CSEC）收集，并将作为CRP初始核心表征研究的一部分进行报告。

Kettler OPP 9527070 Abstract This award supports organic geochemical characterization of Cretaceous-Paleogene sedimentary rocks that are expected to be recovered during the Cape Roberts Project (CRP). The CRP proposes to core four 500 m holes from a fast ice drilling platform in the Ross Sea in 1995 and 1996. The core recovered will be described, curated, and sampled for scientific research. The CRP has the potential to answer significant questions regarding the history of the West Antarctic rift system, the development of continental ice sheets in Antarctica during the Cretaceous and Paleogene, and the response of biota to climatic deterioration and the development of seaways. Organic geochemical measurements are relevant to these issues and so are included in the initial core characterization studies. The work supported here includes measurement of whole-rock carbonate carbon, total carbon, total nitrogen, and total sulfur, analysis of the elemental composition of kerogen in selected samples, and gas chromatographic analysis of the solvent-soluble organic matter in selected samples. These data will be collected in the Crary Science and Engineering Center (CSEC) at McMurdo Station and will be reported as part of the initial core characterization study of the CRP.
