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~(14)C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。 According to the analysis of sporo-pollen in the sections of Fuyun Turpan and Gankou, the climate of the sedimentary facies in these sections is mild and dry, and the vegetation is desert steppe or savanna. The results of sporopollen analysis and ~ (14) C age data indicate that the geologic time of these sediments is Holocene. By analyzing the sporopollen collected from the sediments on both sides of the fault, it was found that the fault did not form earlier than Holocene.
