摘要
The Luoyunshan fault zone is located west of Linfen basin,controlling the western border of the basin.The measurement of the terraces in eight gullies along the Luoyunshan fault zone shows that these gullies has five terraces: T1~T5.The heights of these terraces are about 3m,8~10m,about 20m,about 30m and 40~50m respectively.The dating data of the terraces and the faulted landforms investigation shows that the Luoyunshan fault zone has had many activities since Late Quaternary.Since the Middle-Late Pleistocene an uplift rate of the terraces is 0.41mm/a,and 0.75mm/a since Holocene.An increasing trend of the uplift rate of the terraces along the Luoyunshan fault zone from the Middle-Late Pleistocene to Holocene,reflects the tectonic uplift tendency of the fault zone has gradually increased since the Late Quaternary.This is in good agreement with the sedimentation rate of Linfen basin which also has an increasing trend from the Late Pleistocene to Holocene
