| 摘 要： | 新疆火山活动强烈 ,火山岩类型多 ,出露广泛。依据火山岩特征和时空分布规律 ,新疆火山岩分布区域可以划分两个较大级别的火山岩分区单元 :第一级为火山岩区 ,第二级为火山岩带。全区共划分出 6个火山岩区和 30个火山岩带。火山岩分区的划分对火山岩、地质构造和矿产的研究具有重要的意义和实用价值

| Abstract: | Strong volcanic activities,and diversified and extensively- outcropping volcanics appear in Xin- jiang.According to the characteristics and time- space distribution of volcanics,two relatively high- grade vol- canic divisions are classified,that is,volcanic region the first grade,and volcanic belt the second grade.In total 6volcanic regions and 30 volcanic belts are subdivided in Xinjiang.The subdivision has both scientific and practical significance on studying volcanics,geological structures and minerals. |
