摘要：
Nd-Sr isotopic compositions of 12 Mesozoic granitoids from Jiangxi Province have been reported. They show loe-ε(-13.8—- 8.3), high-l(0.71069—0.73981) and old t(2087—1635 Ma). Comparison between the Sm-Nd isotopic compositions of the granitoids and those of the basement metamorphic rocks suggests that these granitoids were mainly derived from the metasedimentary rocks. There is an east-west trend Mesozoic granitoid zone with lowtfrom S. Jiangxi to S. Fujian. The origin of these granites was preliminarily discussed.
