Abstract
Nd-Sr isotopic compositions of 12 Mesozoic granitoids from Jiangxi Province have been reported. They show low-∈ND(−13.8–−8.3), high-/Sr(0.71069–0.73981) and oldt DM (2087–1635 Ma). Comparison between the Sm-Nd isotopic compositions of the granitoids and those of the basement metamorphic racks suggests that these granitoids were mainly derived from the metasedimentary rocks. There is an east-west trend Mesozoic granitoid zone with low-tDM from S. Jiangxi to S. Fujian. The origin of these granites was preliminarily discussed.
