潮州柘林湾黄冈河断裂带第四纪活动特征及地质环境效应
Quaternary activity characteristics and geological environment effects of Huangganghe fault zone in Zhelin Bay,Chaozhou
摘要
Abstract
The Zhelinwan Member of the regional Huangganghe fault zone was formed in the middle Yanshan period and cut through the late Jurassic and early Cretaceous rock mass.Observations indicate that the silicized fragmentation rock exceeds 70 m in width,while the hidden main fault fracture zone spans over 200m,exerting control over the deposition from the late Pleistocene Nansha Member(Qp3ns)to the Delta layer(Qp3sj)(17.5±1.0 ka)in the area.It also shows synsedimentary fault characteristics.Since the Holocene,the differences in lithology,thickness and spatial distribution of sedimentary layers on both sides of the fault have become smaller between 8.8±0.5 ka and 4.0±0.3 ka,which may indicate relatively weakened fault activity.Since 4400 a,there has been a depositional disjunction in the fault zone,and the crust around the fault zone has also shown obvious vertical uplift.关键词
