新生代

2B–f. Instead, they are bounded by the Cenozoic lithification domain to the right, and stream off to lower δ18O values that are readily attributable to later metamorphic alteration.

相反的，这些数据被局限在新生代成岩作用区域左边，氧同位素相对较低的比值可以认为是后期变质交待作用的结果。

On the basis of studies of Cenozoic deposits, lithification is most rapid in sediments in coastal areas where meteoric ground waters mix with marine pore fluids. The process yields a roughly co-variant relationship between δ13C and δ18O in which δ13C decreases as δ18O decreases Fig.

在新生代的沉积中，岩化作用在海岸地区的沉积物中发生的最快，这一地区海洋孔隙流体更多地与大气水发生了混合，这一过程造成了碳氧同位素同步的发生减少。

These data are incompatible with the excursion scenario unless (1) carbonates deposited during a negative δ13C excursion are more susceptible to later δ18O metamorphic alteration in proportion to their negative δ13C value, or (2)δ18O of sea water decreases as δ13C of sea water decreases to produce an array that fortuitously resembles the Cenozoic lithification domain Fig.

这些数据与想象的同位素漂移情况不一致，有两个因素应当考虑在内。1。碳酸盐在δ13C存在负值漂移时沉积更加容易受到后期δ18O变质交代作用的影响，这种影响与δ13C成比例。2。海水δ18O与δ13C的同步减少使得数据出现在图表上的近似新生代成岩作用区域，这种情况属于偶然情况。
