| 摘 要： | 新疆阿拉套山南坡东西向展布的花岗岩石的岩石化学研究表明，本区同时存在Ｉ型和Ｓ型两种类型的花岗岩，其分布受构造环境控制，靠近古板块缝合线为Ｉ型花岗岩分布区、远离古板块缝合线为Ｓ型花岗岩分布区。源岩性质和作用强弱等因素可能是造成岩石化学成分差异的原因。

| Abstract: | The study of major elements of granitoids from the south slope of the Alatao Mountain, Xinjiang, indicates that there are both I-and S-type granites in the studied region. Distribution of the two types of granites is tectonic-controlled. I-type granites are located near the paleo-plate boundary, while S-type granites do away from the suture. Differences in major element compositions of different intrusions may be caused by differences in the source rocks and mixing processes. |
