Data from Black and White Layers

Abstract: This dataset reports carbon and nitrogen isotopic composition and the C/N ratio of the organic material present in the newly discovered occurrence of thick sequences (∼100 m) of Late Oligocene and Early Miocene (∼24.9 to ∼20 Ma) interbedded organic-rich sediments (sapropels) and pelagic (organic poor) carbonates at Sites U1466 and U1468 drilled in the Maldives archipelago during the International Ocean Discovery Program (IODP) Expedition 359.

摘要：本数据集记录了国际大洋发现计划（International Ocean Discovery Program, IODP）第359次科考航次在马尔代夫群岛钻取的U1466与U1468站位中，新发现的渐新世晚期-中新世早期（约24.9至20 Ma）互层富有机质沉积物（腐泥层，sapropels）与远洋（贫有机质）碳酸盐岩厚层序列（约100 m）内赋存有机质的碳、氮同位素组成及碳氮比（C/N）。
