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.
