Abstract

Ce isotopic compositions in several terrestrial and extraterrestrial materials were determined in order to investigate the applicability of using Ce as an isotopic tracer to geological processes. Owing to the low abundances of **1**3**8La and **1**3**8Ce in nature, the measurements of **1**3**8Ce/**1**4**0Ce ratios of natural samples have relatively large ( greater than 0. 02%) errors, and the variations in Ce-isotope ratios were barely resolved. A tenuous anticorrelation was observed between epsilon //C//e and epsilon //N//d for terrestrial basalts and granites, indicating that with some improvement in analytical techniques the Ce isotopic composition may prove useful as a tracer for geological processes.
