Climatic fluctuations from the Eocene to the Miocene highlight the importance of investigating the paleoenvironment of the latest Eocene to the Middle Miocene Lark Formation in the Danish North Sea. This study investigates immature sedimentary organic matter in the Lark Formation using 54 cuttings samples and one core sample collected from seven wells in the eastern North Sea Basin. Organic petrography and molecular geochemistry analyses were performed to determine the variations in the quantity and origin of allochthonous and autochthonous organic matter. Additionally, the study assesses the impact of climate fluctuations on marine productivity in the eastern North Sea Basin and land plant vegetation at the basin margins during the latest Eocene to the Middle Miocene.

对丹麦北海 Lark 组陆地植物和海藻有机质的有机岩相学和地球化学见解


从始新世到中新世的气候波动凸显了研究丹麦北海最新始新世至中新世中新世 Lark 组的古环境的重要性。本研究使用从北海盆地东部 7 口井收集的 54 个岩屑样本和 1 个岩心样本调查了 Lark 组中未成熟的沉积有机质。进行有机岩相学和分子地球化学分析，以确定异质和原生有机质的数量和来源的变化。此外，该研究还评估了最近始新世至中新世期间气候波动对北海盆地东部海洋生产力和流域边缘陆地植物植被的影响。
