摘要：

Sm-Nd isotopic compositions of associated amphibolites, TTG gneisses and granitic gneisses from the Archean Kongling Complex of the Yangtze Craton, South China are systematically analyzed. The results show that the amphibolites and TTG gneisses have a similar age of ca. 2 700 Ma, which well agrees with zircon U-Pb dating of previous studies. However, their epsilon(Nd)(t) are different, suggestive of possible dissimilarity in source composition.
