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，从公开文献中汇编得到的碳酸盐碳同位素（carbonate carbon isotope）与牙形石磷灰石氧同位素（conodont apatite oxygen isotope）数据集合。该数据集被应用于频谱分析（spectral analysis），以探究全球碳循环（global carbon-cycle）与气候系统中的长期旋回性。
