【摘要】 古遗址、古墓地发掘过程中的自然变形研究是反演或充实历史和史前变形历史记录的重要工作内容之一.近期我省地震部门会同省文物考古部门,对皖西霍山戴家院考古现场进行专题发掘调查,发现了与构造运动有关的地裂缝,其中充填有砂线、砂脉.初步研究显示包括两期变形,且均显示高速变形特征,代表两次地震事件.发生时代约相当于西周晚期和春秋中晚期,前者规模较大,含砂裂缝长轴方向平行于近侧的地震活动断裂方向.本次发现及初步分析填补了东部地区西周到春秋期自然变形事件研究空白.更多还原

【Abstract】 The stuudy of natural deformation vestige during the disentombing to the ruins and tumulus is one of the important tasks in inverting or substantiating history and prehistoric deformation records.Recently,the Earthquake Administration cooperates with department of cultural relics and archaeology to explore and investigate Daijiayuan vestige at Huoshan in western Anhui.We found the sand line and sand vein filled in the crack.It may relate with tectonic movement.It shows 2 times of tectonic deformation from the preliminary research,and it shows the characteristic with high rate.They represent 2 earthquake events.It is about equivalent to the later period of Xizhou Dynasty and in the middle-later period of Chunqiu Dynasty in era,the former is larger in scale,with the long axis direction of crack of sand parallel to the direction of the seismic fracture in the near side.This discovery and initial study is the first one about the natural deformation in East China from Xizhou Dynasty to Chunqiu Dynasty.更多还原
