Zircon U-Pb ages and their implications for the South Liaohe Group in :1589 － 1605 the Liaodong Peninsula ，Northeast China. Acta Petrologica Sinica ，31 (6) Abstract Liaodong Peninsula is located in the southeastern part of Liaoning Province ，the basement rocks of which consist mainly of the Archean Anshan-Fushun Complex in the north (Liaobei-Jinan Block)，Archean Jinzhou Complex in the south (Liaonan Block)， and the Paleoproterozoic Liaohe Group and granitoid intrusions (Jiao-Liao-Ji Belt)in between. The Paleoproterozoic Liaohe Group is divided by the Qinglongshan-Zaoerling shear zone into two parts ，the South Liaohe Group and North Liaohe Group ，with more volcanic rocks in the former and more clastic and carbonate rocks in the latter. The South Liaohe Group consists of three rock units ，with a v
