| 摘 要： | 在下/中奥陶统界线附近笔石的生物地层学研究基础上,笔者选择了华南地区奥陶系台地相、盆地相和位于二者之间的过渡相等不同沉积相区5条典型地层剖面,开展了华南下/中奥陶统界线附近笔石动物群的图形对比研究,通过这项研究,进一步明确了华南奥陶系下/中奥陶统界线附近笔石动物群的延限和不同相区笔石动物群的精确对比关系,为开展不同相区之间地层的精确对比奠定了基础。

| Abstract: | Based on the biostratigraphic study of graptolites near the Lower/Middle Ordovician boundary,the authors selected five typical stratigraphic section in such Ordovician sedimentary facies of South China as platform facies,basin facies and the transitional facies between the above two facies to conduct graphic correlation of the graptolite faunae near the Lower/Middle Ordovician boundary.The results shed further light on the duration of graptolite faunae near the Lower/Middle Ordovician boundary in South Chin... |

| Keywords: | Lower/Middle Ordovician boundary graptolite different facies graphic correlation |
