Comparison of stable carbon isotope values obtained from laser ablation including the multiple serial laser scans and single vertical scan (this study), and the more traditional single bulk sampling method ([32]; this study).

Comparison of stable carbon isotope values obtained from laser ablation including the multiple serial laser scans and single vertical scan (this study), and the more traditional single bulk sampling method ([32]; this study).本研究对两种方法获取的稳定碳同位素值进行对比分析：其一为包含多次连续激光扫描与单次垂直扫描的激光剥蚀（Laser Ablation）法，该方法已在本研究中应用；其二为更为传统的单次整体采样法，相关研究参见文献[32]，本研究亦采用此方法。
