| 摘 要： | 在中国阿尔泰山南缘造山带的地质研究工作中发现，在这里存在一套有成生联系的花岗深成岩和火山岩系，它们不是板块汇聚阶段的产物，而是地壳拉张作用阶段的产物，它们形成于被动大陆边缘演化阶段。我们把这种大陆边缘称之为岩浆型波动陆缘，以便与无岩浆活动的大西洋型大陆边缘相区别。

| 关 键 词： | 地壳拉张作用，岩浆型被动陆缘 |

| Abstract: | We found that there were a series of granitoid and volcanic rock,which did not relate to the environment of active continental margin when we study the southern Chinese Altay orogenic belt.They formed in the environment of psssive continental margin and related to extension of continental crust. We call the continental margin Passive Continental Margin with Magmatism in order to differentiate from amagmatic passive continental margin |

| Keywords: | extension process of the crust passive continental margin with magmatism |
