%X The Miaoershan granite batholith is a typical multi-episode granite complex in South China. It is on the rock samples of different periods using Rb-Sr (whole-rock and mineral), U-Th-Ph(zircon) and K-Ar determination technigue. The results indicate that it can be divided four episodes: Caledonian(368Ma ), two sub-episodes: first (131 - 192Ma) and second (94-115Ma).
