Abstract
Well-preserved fossil marine organisms generally yield very positive delta(18)(PO(4)(3-)) values which are considered to result from relatively good preservation of the original oxygen-isotope composition of phosphatic material deposited under isotopic equilibrium conditions in oceanic water whose O(18):O(16) ratio was more positive than that of modern oceans.
摘要
保存完好的海洋生物化石通常会产生非常正的δ(18)(PO(4)(3-))值，这些值被认为是由于在海洋水中同位素平衡条件下沉积的磷酸盐物质的原始氧同位素组成得到了较好的保存，而海洋水的O(18):O(16)比值比现代海洋的更偏正。
