摘要
本文依据南京市及其附近区域(活动断层探测目标区范围)所开展的浅层人工地震探测、槽探、钻探,以及第四纪地层划分、新年代学测试数据等多学科资料,综合评价了长江破碎带的最新活动年代、活动性质、断层相关参数及其与地震活动关系方面的最新认识。
Changjiang fault zone, also called Mufushang-Jiaoshan fault, is a famous fault that is located at the southern bank of the Changjiang river around Nanjing downtown area. Striking in about east-west orientation with the north trending, this fault is near 100kra long and is featured by normal fault mode. At both ends of the fault, there occurred earthquakes with magnitude of 5-6 in the past. Based on the analysis from shallow artificial seismic exploration, trough study, drilling exploration and application of dating techniques, this paper provides the most-up-to-date results regarding to the activity of Changjiang fault, such as most recent active time, faulting mode, the related active parameters and relation to the seismic activity.
