| 摘 要： | 岩石地球化学特征研究表明,阜新-义县盆地义县旋回火山岩属于同源钙碱性火山岩系,岩浆演化序列为基性→中性→中酸性→酸性。火山岩化学成分变化以岩浆结晶分异占主导地位,岩浆分异较好。火山岩形成于大陆边缘活动带,岩浆来源于壳源。

| 关 键 词： | 义县旋回 火山岩 岩浆 钙碱性 结晶分异 壳源 |

| Abstract: | The studies on the lithogeochemical characteristics showed that the rocks of Yixian cycle in Fuxin-Yixian basin belong to a comagmatic calc alkaline volcanic suite,which magma was well differentiated and evaluated from basic to intermediate,to intermediate acid,to acid, the changing of chemical composition mainly was magmatic crystallization differentiation The volcanic rock formed in an active belt on the continental margin,and its magma sourced from the crust |
