Carbon isotope record of profile Gubbio

The carbon isotope record at Gubbio is a composite of the sections Bottaccione (Top of section: K/T boundary) and Contessa Highway (Height of section: 335 m). Heights at Bottaccione are from Premoli Silva and Sliter (1994). Heights at Contessa are from Chauris et al. (1998) +35 m to account for the +25 m correction by Premoli Silva and Sliter (1994) and the 10 m gap (Gardin et al. 2012) at Bottaccione.

古比奥（Gubbio）的碳同位素记录（carbon isotope record）为Bottaccione剖面（剖面顶部为K/T界线（K/T boundary））与Contessa Highway剖面（剖面总高度335米）的复合数据集。Bottaccione剖面的高程数据引自Premoli Silva与Sliter（1994）。Contessa剖面的高程数据源自Chauris等人（1998）的研究结果，需额外增加35米以抵消Premoli Silva和Sliter（1994）提出的25米校正值，同时弥补Bottaccione剖面存在的10米沉积间断段（Gardin等人2012）。
