河北省西北部汉诺坝玄武岩区、山东省东部蓬莱-栖霞和中部临朐-沂水玄武岩区、安徽省嘉山至江苏省六合玄武岩区都是我国东部新生代大陆玄武岩带的重要组成部分。本文报道了上述岩区87个样品的全岩氧同位素组成,进而为讨论玄武岩成因及其地幔源区的性质和过程提供氧同位素的约束。 Hannuoba basalts in the northwestern part of Hebei Province, Penglai-Qixia in the east of Shandong Province and Linqu-Yishui basalts in the central part, and Jiashan in Anhui Province to the Luhehe basalt area in Jiangsu Province are all important components of the Cenozoic continental basalt belt in the eastern part of China. This paper reports on the isotopic composition of the whole rock in 87 samples from the above-mentioned rock areas, and then provides oxygen isotope constraints for discussing the genesis of the basalt and the nature and process of its mantle source area.
