摘要
Granitoids of Tekesi Daban have been subdivided into two successions of the Kulesayi succession with age of 347 Ma in the early Carboniferous period and the Qinaersayi succession with age of 291～292 Ma in the Early Permian period. The Kulesayi succession is a metaluminous rock which is different of the latter (peraluminous granitoids). The Kulesayi succession which belongs to the calc-alkalic rock type is formed in the island arc tectonic setting and the Qinaersayi succession which belongs to the alkalic rock type is formed in post-orogenic episode.
