| 摘 要： | 基于大量的岩相学和岩石化学资料，作者认为，熊耳群火山岩的岩石类型主要为橄榄玄粗岩，安粗岩，粗面英安岩和流纹岩，其次为高钾玄武安山岩、橄榄粗安岩，高钾安山和高钾英安岩；火山岩系列主要为橄榄玄粗岩系，其次为高钾钙碱性岩系；熊耳群火山岩可能是大陆边缘弧弧后火山岩或碰撞后弧火山岩。同时，作者在文中列出了４４个代表性火山岩样品的岩石化学资料和９１３个火山岩，次火山－侵入岩样品的平均化学成分资料。

| Abstract: | Based on a large amount of data on petrography and petrochemistry,the authors suggest that the volcanics of Xiong'er Group are dominantly shoshonites,latites,trachydacites and rhyolites,and secondarily are high K basaltic andesites,mugearites,high K andesites and high K dacites;the volcanic rocks are mainly of shoshonite series,and secondarily are of high K calc alkaline series.Xiong'er Group volcanics may belong to the volcanics in the back of continental mariginal arc or those of the post collision arc |
