| 摘 要： | 复州湾地区石炭纪早期发展史及地层研究有待深入。本文通过有关岩石和化石内容,讨论了传统本溪组的一些问题,认为本溪组应改称本溪群,它代表自奥陶系石灰岩侵蚀面至砾状灰岩顶面一段沉积地层,砾状灰岩顶面标志——平行不整合面,据岩性组合本溪群分为上下两部分(有待建组)。化石资料修正了本溪组时代相当莫斯科期的观点,提出该区本溪群延续时限自早石炭世晚期(相当纳谬尔A期)或更早至莫斯科期中期(Profusulinella带上限),在区域上本溪群是一个明显的穿时单位。

| Abstract: | The paper systematically discusses the problems relating to the traditional Benxi Formation. Based on lithologie features and fossils discovered in Fuzhouwan area, the authors consider that the name of Benxi Formation is not suitable for defining a series of sediments, and propose to replace it by the Benxi Group and to divide it into two parts:upper and lower. On the other hand, the authors infer from the fossils in it that the time of the Benxi Group in studied area ranges from late Early Carboniferous(Namurian A)or earlier, to Middle Moscovian(upper limit of Profusulinella biozone), and has its own characteristic. The results will be helpful to the research of the geologic history of Early Carboniferous Period on the North China Platform, especially in East Liaoning. |
