Li isotope data set of Mesozoic basalts in eastern China

Li isotope data set of Mesozoic basalts in eastern China


This data set mainly includes the results of Li isotopic analysis of Mesozoic basalts in eastern China, including the nuominhe and Wudalianchi areas in Northeast China, Changle, Penglai and Shanwang areas in North China, Mingxi, Minqing, Longhai, qiweishan, Fankeng and Qinglongshan areas in South China, Li isotope data were obtained by MC-ICPMS after acid digestion and ion exchange resin separation of whole rock samples, and the accuracy was better than 0.3 ‰. Li isotopic data of basalts will provide important data support for understanding the evolution of mantle in eastern China. The results show that some Mesozoic basalts experienced weathering due to long surface exposure, and some were altered by the influence of external hydrothermal fluid. There is no large fractionation between the mantle source and depleted mantle of Cenozoic basalts, and some low Li isotopic compositions may be due to the metasomatism of the source mantle by sediment derived melts.
