| 摘 要： | 为研究笔石动物群在早一中奥陶世之交全球分布的控制因素,从以下3个方面进行了分析和研究:①分析了穿越扬子地台笔石动物群的分布特征;②在对笔石体形态功能分析的基础上,探讨了水体深度对笔石动物群分布的影响;③根据当时的古地理格局,并参考现今的洋流分布,建立了早一中奥陶世之交的洋流分布图.在以上研究的基础上,对前人以水体深度作...

| Abstract: | In order to study the controlling factors on the global distribution of graptolite fauna during the Lower-Middle Ordovician transitional period,the authors analyze the following data:(1)the distribution characteristics of the graptolite fauna trans-Yangtze platform,i.e.from basin facies to carbonate platform facies,and the transitional belt in between;(2) the influence of water depth on the distribution of graptolite fauna based on the morphological function analysis of the graptolite rhabdosome;(3) the glo... |
