(Appendix) Total and organic carbon and calcium carbonate at DSDP Hole 64-480

Sediment depth is given in mbsf. Interval and depth figures refer to the top of a 10-cm integrated sample interval, with some 20-cm intervals sampled in homogeneous zones.沉积物深度以海底以下米（meters below sea floor，缩写mbsf）为单位。采样间隔与深度数值均以10厘米组合采样段的顶部为基准，部分均质层位采用20厘米的采样间隔进行取样。
