南京市东郊湖山地区的陈家边断层,其规模不大,延伸仅数公里,它以地表出露清楚、各种断层迹象典型而享有盛名,然而对其性质的认识至今却仍无定论。笔者综合了各种野外地质现象,区域地质构造特征和断层岩的组构分析,对陈家边断层的性质及其发育过程进行了初步探讨,并认为它是显示断层效应的一个典型实例。

The Chenjiabian Fault is located in hushang region in the east suburb of Nanjing. it stretchs only for several kilometers, but is very famous for its wonderful outcrops and various typical phenomena of faults, nevertheless, its properties have not been determined up to now based on the comprehensive analysis of the field geological phenomena, charecter of the regional tectonics and fabric of the fault rocks, the author probes into the properties and the developmental process of Chen jabian Fault and proposes this fault is a very typical sample of the fault effects.
