| 摘 要： | 对内蒙地轴及其南缘(冀北部分)侏罗系煤系的岩性特征及其中所含植物化石进行了研究,并将它们与内蒙古早—中侏罗世含煤地层进行了对比,认为下花园组下部是内蒙古五当沟组在冀北的延伸,应称为五当沟组,上部煤系应为召沟组在冀北的延伸,因此应改称召沟组。

| Abstract: | This article reports plant fossils and lithostratigraphic data from Jurassic coal measures in the Inner Mongolia axis and its southern margin.These fossils can be compared with plant fossils from early-middle Jurassic coal strata in the Inner Mongolia area. We recognize a stratigraphic unit in the early-middle Jurassic Xiahuayuan Formation and regard it as a lateral equivalent of the Wudanggou Formation in Inner Mongolia.The coal measures overlying this unit is regarded as a lateral equivalent of the Zhaogo... |
