Using CHIME geochronological method, the zircons and monazites from the Caoshan and Lishugou plutons are dated. The PbO-UO2* isochron age and weighted average age of the Lishugou pluton are all (173±10) Ma. For the Caoshan pluton, the zircon PbO-UO2* and monazite PbO-ThO2* isochron ages are (178±8) Ma and (177±3) Ma, and their weighted average ages are (175±6) and (177±3) Ma, respectively.
