辽宁核电站温坨子厂址东岗断裂活动性研究

A Study on Activity of the Donggang Fault at Wentuozi Site of Liaoning Nuclear Power Plant

本文在综合地质、地貌、地形变、地震、物探和年代测定等资料的基础上,对东岗断裂的活动性进行了全面分析。所得结果表明,东岗断裂在中更新世时期有过两期活动,但自晚更新世(10万年)以来没有活动,故可鉴定为非能动性断裂。

Based on the data of geology, geomorphology, geophysics, crust deformation , seismology , age dating, etc, this paper presents an analysis of activity of the Donggang fault,the research results show that the Donggang fault has two active periods, (i. e. 10 × 104 - 17 × 104years and 24 ×104 - 33 × 104years)in the middle Pleistocene. However,since the late Pleistocene this fault has not moved and is a non-capable one.
