ODP 763A pollen and leaf wax n-alkane compound distributions and isotopes@en

The data are measurements of leaf wax n-alkane compound abundance and associated metrics of compound distribution, leaf wax n-alkane compound specific carbon isotope measurements, and pollen abundance from sediments of Ocean Drilling Program core 763A from the Exmouth Plateau off north-west Australia. From these data, aspects of late Cenozoic paleovegetation were reconstructed, with a particular focus on the onset of C4 vegetation expansion in the region.本数据集包含澳大利亚西北海域埃克斯茅斯高原大洋钻探计划（Ocean Drilling Program）763A岩心沉积物的多类分析数据：叶蜡正构烷烃（n-alkane）化合物丰度及化合物分布相关指标、叶蜡正构烷烃化合物特异性碳同位素测定结果，以及沉积物花粉丰度数据。依托上述数据，研究重建了该区域晚新生代古植被的演化特征，重点聚焦于该区域C4植被（C4 vegetation）扩张的起始过程。
