The early history of the Yangtze Block has not been well constrained yet,due to the scarce outcrops of Archean to Paleoproterozoic rocks.In this study,we report an integrated study of zircon U-Pb age,major and trace element data for the association of I- and A-type granites from the Lengshui complex in the central of the Middle Yangtze Block.Zircon U-Pb dating yields a weighted mean 207Pb/206Pb age of 1960 ±19 Ma for I- type granite.This age is interpreted as the formation age of the Lengshui complex.
