1.
Through field investigation, the most complete Paleozoic section in northern Tibet was measured in the Zakang area, Xainza County, where the Early Ordovician Arenigian graptolite fauna was discovered.
测制了目前藏北地区最为完整的申扎扎扛古生界剖面,发现了早奥陶世阿雷尼格期的笔石动物群,确定该动物群属于西藏已知层位最低、时代最早的动物群,建立了下奥陶统扎扛组(O1z)。

Correlation with other areas has revealed that the graptolite fauna in this area belongs in a transitional type between the Yangzi area and the Jiangnan area, and that a break of a certain magnitude may have existed in early Early Siluri.
通过与其它地区同期笔石带对比 ,发现本区笔石动物群属扬子区和江南区的过渡类型 ,并且早志留世早期可能存在一定规模的间断。
3.
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。
5) change and succession
