Abstract: Recognition of natural deformation during excavating ancient ruins and tomb is an important work of tracing or enriching the history and the historic records about prehistoric deformation.Recently,the earthquake department in cooperation with the cultural relic archaeology department conducted the special excavation research at the archaeological site of Gaixia ruins,Guzhen,Anhui,and discovered fault and cracks,which are demonstrated by preliminary study to be the vestiges of two coeval strata deformation events.The high speed deformation characteristic possibly represents two strong earthquake events,and the time is approximately in the Late Dawenkou culture stage.The crack was formed earlier than the fault.The discovery is the first in the eastern China.This work has filled the gap of research on recognition of natural dislocation event in Late Dawenkou culture stage and may improve the recognition of seismological relics in cultural stratum of human being in eastern China,especially in the transition belt between the north and south of China in the Changjiang-Huaihe area.

摘要： 古遗址、墓地发掘过程中自然变形的识别研究是反演或充实历史或史前地震变形资料的重要工作。地震部门与文物考古部门合作,对安徽固镇垓下遗址考古现场进行了专题发掘研究,发现了断层和裂缝,初步研究显示为同期2次层位变动事件的遗迹,发生时代约相当于大汶口文化晚期,该工作有助于推动中国东部人类文化层中地震遗迹的识别。
