Abstract
The orogenic belt of northern China is characterized by widely develop ed postorogenic I fractionated and A-type granites in the Phanerozoic. The isotopic data display relatively high epsilon(Nd)(t) and Pb-206/P b-204 values and low I-Sr ratio. The low T-DM model ages (<100 Ma) sug gest that the Neo-Proterozoic-Phanerozoic is one of the main stages in the continental growth.
