説明
In the Huanggoushan area of the Jilin Province, two types of Mesozoic granites occur : (hornblende)-biotite granite represented by Caoshan, Lishugou and Laotudingzi plutons, and garnetbearing muscovite granite represented by Yaolin pluton. Using CHIME geochronological method, the zircons and monazites from the Caoshan and Lishugou plutons are dated. The CHIME zircon age of the Lishugou pluton is 178±9 Ma. For the Caoshan pluton, the CHIME zircon and monazite ages are 175±8 Ma and 177±6 Ma, respectively. It is concluded that the Mesozoic granitic magmatism in the Huanggoushan area took place at ~175 Ma of Middle Jurassic, not Late Triassic as previously thought. These age data provide some new information about the studies of the igneous activity and geodynamics of eastern China during Jurassic.
