Research of the Late Quaternary Recent Activity of the Middle Segment of Kouquan Fault
摘要
Abstract
Systematic research of the characteristics of late Quaternary activity of the middle part of Kouquan fault has been done through conducting 1:50000 geologic mapping combining with remote sensing interpretation of spot imaging, field validating and chronology research of the research area. Studies suggest that the middle part of Kouquan fault has had strong activity since the late Quaternary which controls the tectonic evolvement of the nearby mountains and Datong basin. The recent activity of this fault has faulted the sandy gravel layers of T1 terrace and the lower part of dark loessial soils over the terrace on the north of Chanfang village. The maximum vertical displacement is over 3m in the area between Xiaoyukou village and Louzikou village, and to the south of Dayukou village and the north of Emaokou village, the displacement decreases to 0. 5m and 0. 25m respectively. Based on the recent faulted landforms and combined with dating, we determined the age of recent activity of the fault in the research area to be between 7. 71ka B.P. to 3. 00 ka B.P. Discussions are made on this in combination with previous research.关键词
