本文对辽宁南票及内蒙古大青山区上石炭统—下二叠统中火山事件沉积物进行了系统的岩矿鉴定。差热、X光、电镜测试及微量、稀土元素定量分析,两剖面自下而上共划分出12期火山事件沉积序列,包括了34～39层火山事件沉积层。由于各层均具有特定的岩石
In this paper, systematical rock and mine identification of volcanic events in the Upper Carboniferous and the Lower Permian in Nantou, Liaoning and Daqingshan area, Inner Mongolia, is carried out. Differential scanning calorimetry, X-ray and electron microscopy, and quantitative analysis of trace and rare earth elements, 12 sections of volcanic sedimentary sequences were divided from bottom to top, including 34 to 39 volcanic sedimentary layers. Because each layer has a specific rock
