使用扫描质子微探针及微束ＰＩＸＥ定量分析技术对我国广东南雄盆地晚白垩系地层中的病态恐龙蛋壳化石样品的微米区域内元素成分进行了测定和研究。结果表明，恐龙蛋壳微区内主要由Ｔｉ、Ｖ、Ｃｒ、Ｍｎ、Ｃｏ、Ｎｉ、Ｃｕ、Ｚｎ、Ａｓ、Ｒｂ、Ｓｒ、Ｙ、Ｚｒ、Ｓｂ、Ｂａ和Ｐｂ等微量元素组成，而它们的分布特征则不相同。其中，Ｃｒ、Ｍｎ、Ｎｉ、Ｃｏ、Ｃｕ、Ｚｎ、Ａｓ、Ｒｂ、Ｙ、Ｚｒ和Ｂａ的分布形式基本一致，主要分布在蛋壳的锥体层（近内表层）中；而Ｓｒ元素则主要分布在蛋壳的柱状层（近外表层）中。根据这些微量元素的含量及分布特征，对恐龙灭绝的原因作了初步的探讨
The elemental composition of the pathogenic dinosaur eggshell fossil samples in the microregion of the Late Cretaceous strata in the Nanxiong Basin, Guangdong Province, China were measured and determined by scanning proton microprobe and microbeam PIXE quantitative analysis. The results showed that the dinosaur eggshell mainly consisted of trace elements such as Ti, V, Cr, Mn, Co, Ni, Cu, Zn, As, Rb, Sr, Y, Zr, Sb, Ba and Pb while their Distribution characteristics are not the same. Among them, the distribution of Cr, Mn, Ni, Co, Cu, Zn, As, Rb, Y, Zr and Ba are basically the same and mainly distributed in the pyramidal layer Distributed in the columnar layer of eggshell (near the outer surface). Based on the content and distribution characteristics of these trace elements, the causes of the extinction of dinosaurs were preliminarily discussed
