显微拉曼光谱对恐龙化石内部成分研究

Study of Dinosaur Fossils by Micro-Raman Spectra

文章对云南省三个不同时期的恐龙化石内部成分进行了研究。拉曼光谱结果表明,三个不同时期恐龙化石内部的主要成分是CaCO3晶体,在早、中侏罗纪化石内部发现有SiO2晶体,而晚侏罗纪化石内部则没有。它表明晚侏罗纪化石的硅化环境条件与早、中侏罗纪化石的硅化环境条件相差较大。实验所获资料可为恐龙化石源地及年代鉴别提供一定的依据。

Dinosaur fossils from three different Jurassic periods were studied by micro-Raman spectroscopy. It was found that the main compound in the inner part of the dinosaur fossils is calcium carbonate (CaCO3) crystal. Within early Jurassic and middle Jurassic there was silicon dioxide crystal, but within late Jurassic there was not. This fact indicated that the environmental conditions for silicon dioxide being formed between late Jurassic, and early Jurassic and middle Jurassic were quite different. The experimental data are valuable for identifying the source site and age of dinosaur fossils from Chuxiong.
