Data for: Pacing of the late Ordovician and Silurian carbon cycle by a ~4.5 Myr orbital cycle

Carbonate carbon isotope and conodont apatite oxygen isotope data compilation from the literature for the Late Ordovician to Early Silurian. This data set was used for spectral analysis to determine any long-term cyclicity in the global carbon-cycle and climate.

本数据集为晚奥陶世（Late Ordovician）至早志留世（Early Silurian）时期文献收录的碳酸盐碳同位素与牙形石磷灰石（conodont apatite）氧同位素数据汇编。该数据集被应用于光谱分析，旨在探明全球碳循环与气候中是否存在长期旋回性。
