| 摘 要： | 据对新疆富蕴吐尔洪及干沟等剖面的孢粉分析,揭示这些剖面沉积时期的气候温和干燥,植被为荒漠草原或稀树草原。孢粉分析结果及14C年龄数据说明,这些沉积物的地质时代属全新世。通过对取自断层两侧沉积物的孢粉分析研究,获知此断层的形成时间不会早于全新世

| Abstract: | The studying sections are situated in the northwest and southeast of the Fuyun county, Xinjiang. Many pollen grains of shrub and herb plant have been found in the sediments from the sections of Tuerhong, Gangou, Kalaxiangeer and Wulunguhe, mainly belong to Ephedra sp., Artemisia sp., Chenopodiaceae and Compositae.On the basis of the analysis results it is believed that the vegetation related to the sediments of the sections is mainly typical one of a desert-steppe and steppe vegetation.The result of sporo-pollen analysis shows that there was a climatic fluctuation during the formation of the sediments of these sections. The prevailing climate was warm and dry.The results of pollen analysis are comparable with the pollen data on the Holoce-ne sediments in many regions of our country. Moveover, the seven samples from these sections for 14C dating give the age value of 2000-7000a. For this reason the four studying sections can be ascribed to the Holocene.Based on palynological data from both sides of the fault in Gangon section, the geological age of the fault formation can be infered to be impassable Holocene. |
