High-resolution δ18O and δ13C records across the Piacenzian/Gelasian boundary in the Monte San Nicola section (Sicily, Italy)

Level: This elevation is measured with respect to the reference level: the Nicola bed (sapropel layer A5), whose top is typically used as a lithological marker to highlight the Piacenzian/Gelasian boundary.

高程项：本次高程测量以参考基准面尼古拉层（Nicola bed，即腐泥层A5）为参照；该层顶面通常被用作岩性标志层，用以标示皮亚琴阶与格拉斯阶的地质分界。
