摘      要：Dahuabei pluton in the Wulashan area,Inner Mongolia,is an alkaline and peraluminous granitic ***-ICPMS U-Pb dating of zircons indicates that this pluton crystallized at 330±10 *** pluton did not experience apparent zircon *** consistent temperatures between Zr saturation(765℃) and the average zircon-rutile Ti equilibrium(780℃),together with zircon ages and their CL images,indicated that there were no inherited zircons in this *** the simulation of the dry-system crystallization process of magma cooling at 200 MPa and 1100-709℃,the phase diagram and composition evolution tendency of different phases were *** magma reached its liquidus at 1069℃.Sanidine was the first crystallized phase;at 709℃the residual magma was less than 4%,and the range of 1069-719℃should be the most suitable approach to the real *** is shown that at least some part of the pluton underwent such isobaric equilibrium crystallization processes during its crystallization.
