Investigation of Terraces along the Luoyunshan Piedmont Fault Zone and Its Tectonic Implications
摘要
Abstract
Located at the west of the Linfen basin, the Luoyunshan piedmont fault zone controls the western boundary of the basin. According to the measurements of the terraces in eight gullies along the Luoyunshan fault zone, five levels of terraces, namely T1 ~ T5 have developed in these gullies. The heights of terraces T1, T2, T3, T4 and T5 are about 3m, 8 -10m, about 20m, about 30m and 40 ~ 50m, respectively. The dating data of the terraces and investigation of the faulted landforms show that the Luoyunshan fault zone has experienced much activity since the Late Quaternary. The uplift rate of the terraces was 0. 41mm/a since the Middle-Late Pleistocene, and 0. 75mm/a since the Holocene. The increasing trend of uplift rate of the terraces along the Luoyunshan fault zone from the Middle-Late Pleistocene to Holocene indicates the tendency of gradual tectonic uplift of the fault zone since the late Quaternary. This is in good agreement with the increasing trend of subsidence rate of the Linfen basin from the Late Pleistocene to Holocene.关键词
