太白维山火山岩系序列相划分及火山活动特征

太白维山火山岩系为晋东北地区中生代火山断陷盆地产物。通过工作研究，确定陈我内岩系的岩石类型及空间分布；指出了两大岩系为两个岩浆源的产物及各序列相的成因类型；确定了水下火山碎屑涌流相的存在，并提出了对形成岩浆蒸气爆发岩的新认识。

Division of Sequential Facies of Volcanic Rock Series and its Volcanic Activity Features Studying of Taibaiwei Mountain

Volcanic rock sequence of Taibaiwei Mountain in the northeast rigion of Shanxi province is the product of volcanic fault basin of Mesozoic era According to the result of studying We have ascertained the rock type and spatial distribution;the two rock series from two different magmatic sources and their genetic types of each sequential facies;the existence of the volcanic arenite surge facies under water And finally a new viewpoint about the formation of magmatic vapor explosive rocks is suggested
