The influence of SST on the distribution of graptolite fauna was consequently analyzed based on the study of graptolite sequence of Dawan Formation at Huanghuachang section and the data of the distribution of graptolite fauna on South China.
本文通过对宜昌黄花场剖面和宜昌陈家河剖面大湾组83件样品和陈家河剖面红花园组2件样品的碳氧同位素测试数据,分析了奥陶纪大坪期海水表面温度的变化;并以宜昌黄花场剖面大湾组笔石序列为基础,结合华南地区笔石动物群的分布情况,分析了海水表面温度的变化对笔石动物群地理分布的影响,提出温度变化仅是影响笔石动物群地理分布的间接因素,前人的纬度分带学说值得进一步探讨。
