| 摘 要： | The geochemical characteristics of rare earth elements of A type and Ⅰ type granites were studied in the Sawuer region, Xinjiang. The characteristics of two types granites are different obviously,because the A type and Ⅰ type granites formed at different stage of the post-collisional period. The Sentasi intrusion and Wokensala intrusion are the Ⅰ type granites formed at the late of post-collisional period, and there is extrusion translating to extension stress. The characteristics of rare earth elements show that the fractional crystallization of the Ⅰ type granites is indistinct, and the sources of the Ⅰ type granites come from the mantle. The Kuoyitasi intrusion and Qiaqihai intrusion are the A type granites formed at the end of post-collisional period, and there is extension stress. The characteristics of rare earth elements show that the fractional crystallization of the A type granites is distinct. The sources of the A type granites come from the mantle but interfused by the crust.
