摘　　要：分析了聊城—兰考断裂带形成和地质背景,将断裂带划分为3段,分述各段不同时代构造特征和地震活动等。土壤汞气、氡气测量得出,该区域存在明显的汞气、氡气异常,且异常位置接近,异常区宽度多在90～200m,表明地壳存在着汞气和氡气向上运移通道,证实了隐伏断裂存在,而且具有活动性。The Liaocheng-Lankao fault can be divided into three parts based on an analysis of its geological background.This paper describes the characteristics of geological structure and seismic activity of every part in different geological periods.The results show that there exist obvious mercury and radon anomalies in this area.The anomalies are close to each other,and the widths of the anomaly areas are mostly 90～200 m.All these facts suggest that a buried fault does exist,and the fault is an active fault.

关 键 词：聊城—兰考断裂 地质背景 断裂特征 汞、氡气异常
