The geological-geochemical features of the Zhaibei and Pitou Granite Batholith reveal that the emplacement depth is 7.5 km and temperature of the enclosing rock 250 ℃, the initial temperature of the magma 950 ℃. Based on the data mathematic model is established calculating that after emplacement the cooling period from the initial magma temperature to the crystallization is 4.04 Ma at Zhaibei and 3.97 Ma at Pitou; the prolongation period (ΔtL) caused by latent heat release 3.02 Ma and 2.96 Ma,  respectively. In combination with isotopic ages of 173.8 Ma and 182.3 Ma which represent the crystallization age, the emplacement ages at Zhaibei and Pitou are estimated to be 195.2 Ma and 194.4 Ma suggesting that the emplacement of the Zhaibei and Pitou granite Batholith took place in the Indo-Sinian Period.
