Activity of the Northeasten Branch of Fangcheng-Lingshan Fault Zone in Lingshan,Guangxi,China
摘要
Abstract
Seismic activity in northeast branch of Fangcheng-Linshan fault appeared most frequently in Beibu Gulf economic zone.The work of this paper is to identify the deformation characteristics and activity of northeast branch of Fangcheng-Linshan fault,especially the occurrence and its changes in depth,the scales and spreading characteristics of the faults in the key parts.Areal distribution characteristics and activity of the northeast branch of the Fangcheng-Lingshan fault zone in Lingshan was preliminary discusses by remote sensing interpretation,geological and geomorphological survey,as well as shallow seismic reflection and ground prospecting radar（GPR）.The results indicated that the fault was offset by a number of northwest-trending faults,east and west margin of which are Lingshan fault and Shitang fault,respectively.Linshan fault offset the alluvial fan terraces formed in late Pleistocene.The streams were dextral at Linshan fault.Shitang fault presented a fracture zone with 250 m width,where secondary faults were dense.The images of geophysical exploration showed that both of the two branches of Fangcheng-Linshan fault had a relative strong activity since the Late Pleistocene.关键词
