摘要/Abstract

摘要： 发现于河南省西峡盆地的恐龙蛋化石群产于白垩纪末期的典型红色粘土地层，因此该化石本身可能包含着当时地史时期全球或区域环境灾变记录。利用显微镜观察恐龙蛋的表观特征；利用XRD和XRF研究发现蛋内外粘土的成分极其相似，进而推断西峡恐龙蛋化石蛋腔内的物质源于蛋腔外部；通过扫描电镜/能谱分析发现蛋壳表面存在裂纹现象，同时在蛋体内发现了针铁矿、铜锌氧化物、硫酸钡、氧化硅等颗粒,并对其形成和来源给出了适当的解释。并基于实验结果对K/E转折时期的环境灾变机理进行了初步探讨。

Abstract: The dinosaur egg fossil group found in Xixia Basin, Henan Province occurs in the typical red clay strata in the Late Cretaceous. Therefore, the fossil itself probably recorded the global environment disaster information at that time. We have observed the appearance and surface features of the eggs through microscope. With the help of XRD and XRF methods it is found that the material compositions of the egg’s interior are extremely same as the clay of the egg’s exterior, therefore, we concluded that the material in the interior of the dinosaur eggs found in the Xixia Basin is derived from that of their exterior. We found the cracks on the surface of the dinosaur eggs by SEM. We also found particles of goethite, oxide of copper and zinc, barium sulfate and so on within the eggs, and gave an appropriate explanation on their formation and source. Based on the experimental results the environment disaster mechanism during the K/E transition period has been discussed.

Key words: dinosaur egg fossil, clay, goethite, Red beds, Xixia Basin
