Geochronology ，origin ，sources and tectonic settings of Late Mesozoic two-stage granites in the Ganzhuermiao region ，central and southern Da Hinggan Ｒange ， :1961 － 1981 NE China. Acta Petrologica Sinica ，30 (7) Abstract The Da Hinggan Ｒange (Great Xing ’an Ｒange)is located in the eastern section of the Central Asian Orogenic Belt (CAOB)and also regarded as the middle-western section of the Xing-Meng Orogenic Belt. It experienced strong magmatic activities that produced widespread granitoid intrusions during Late Mesozoic. Those granitoids have been studied intensively ，but few of them have been reported from the Ganzhuermiao region in the middle-southern Da Hinggan Ｒang
