Abstract: Based on studying of satellite and aerial photographs, we made field investigations and sampling to the fault which occurred in bredrock area of northern Dabie mountain. The particular emphasis is laid on research of dislocation geomorphology and deformation material, and analysing the time space characteristic of seismological activity. We obtained information of the fault including its active time mode, and relation to earthquakes. It offers an example for research way to active behavior of the fault in bedrock area.

摘要： 在1/20万TM片和1/5万航片解译判读的基础上,对大别山东北部基岩区活动断裂进行野外验证、观测和取样工作,侧重于断错地貌和断裂变形物质微观滑移方式标志的研究,结合地震活动的时空特征分析,获取了断裂活动时代、活动方式及其与地震活动的关系等一系列信息,为探索基岩区断裂活动习性的研究途径提供了一个实例。
