| 摘 要： | 皖西霍山戴家院西周-春秋晚期遗址发掘调查中,发现了与构造运动有关的地裂缝,其中充填有粉细砂,初定为地震液化遗迹.从变形物质的定向微观分析中发现了大量显微级地震遗迹标志,如负荷构造,流动构造,截断面,有机质悬浮,等等.这些发现和认识从微观角度验证了遗址所在地区西周-春秋晚期曾发生两次地震事件.上述工作在一定程度上丰富和发展了对我国东部地区史前地震事件的识别和研究方法.

Significance and Microscopic Analyzing of Deformation in Cultural Remains of the Nestern Zhou Dynasty-Late Spring and Autumn Period at Daijiayuan Ruins at Huoshan, Anhui Province |

| Abstract: | In the excavation surveying to Daijiayuan vestige in the Western Zhou Dynasty-Late Spring and Autumn Period at Huoshan in Western Anhui, ground crack related to tectonic movement was found filled in powder fine sand. This phenomena was confirmed initially to seismic liquefaction. A lot of microscopic seismic relics, such as load structure, flow structure, truncation plane, organic matter suspend, and so on, were found during directional microscopic analysis to the deformation. These findings prove that there were two earthquakes in the Western Zhou Dynasty-Late Spring and Autumn Period at the area. The work enriches and develops research methods to identify prehistoric earthquake event in Eastern China area to a certain extent. |
