摘　　要：本文通过在河南新密、洛阳和南阳等地的实地考察,发现了一批存在于文化遗址中的自然变形现象,时代涉及新(旧)石器过渡期、东周到北魏时期等。其中在新密李家沟旧石器向新石器过渡期遗址发现三组裂缝,可代表三次构造变形活动。洛阳汉魏故城发现两类裂隙,一类穿切性较好,应为构造裂隙;另一类贯通性差,应为干燥收缩裂隙。南阳东周文化遗址发现两组充填裂隙,一组走向北东,一组走向北西,两组正交,被砂土充填,应为地震液化脉体,显示所在地区东周后有地震活动发生。初步研究表明,这些自然变形现象与当地区域构造方向具有一定的相关性,说明这些遗迹为史前地震事件记录的可能性较大,进一步分析判定这些自然变形现象的形成机制,对河南地震考古工作及历史地震研究的进一步开展具有重要的现实意义。We have found a number of new natural deformation phenomenon through on-the-spot investigation in Henan, Xinmi, Luoyang and Nanyang, whose age relates to the Neolithic-Paleolithic transition period, the Eastern Zhou Dynasty to the Northern Wei period, etc. Three groups of cracks representing three tectonic activities were found in the Lijiagou site of Xinmi city. In Han-Wei Luoyang city, we found two types of cracks, one is structural fissure with clear cross cut relation, and the other is drying shrinkage crack with bad penetrating. Two sets of orthogonal filling cracks were found in the Eastern Zhou dynasty cultural sites in Nanyang, one group towards the northeast and another towards the southeast. They display the earthquake liquefied vein body, indicating earthquake activity after the Eastern Zhou dynasty. Preliminary studies suggest that these sites are most prehistoric records of seismic events. It has an important practical significance to the further research to determine the formation mechanism of these natural deformation phenomenon of the seismic archaeology and historical earthquake of Henan province.
