摘　　要：通过对江西余江盆地玄武岩地球化学特征的研究得知,研究区玄武岩主要为基性岩类,局部富集轻稀土等元素,认为中国东南部内陆晚白垩世与沿海一带的构造环境类似,均处于岩石圈伸展环境。According to the research on geochemical features of basalts in the Yujiang Basin of Jiangxi Province,the basalts in the study area are mainly basic rock types and are locally enriched with light rare earth and other elements.The structure environment of the inland Late Cretaceous in southeast China was similar to the coastal area,and both of them were in the lithosphere extension environment.

关 键 词：地球化学 玄武岩系 晚白垩世早期 余江盆地
