断层面弯曲上凹、往深处逐渐变平、形似犁形的断层被称为犁形断层(Listric fault),国内有称“铲形断层”、“犁状断层”或“犁式断层”的,也有称“倾斜断层”、“箕形断层”、“箕状断层”的。早在1904年,Suess就提出了犁形断层的概念。Cloos和Mohr等还对犁形断层进有了实验研究。近几年,世界各地广泛开展了人工地震勘探,大量的反射地震资料、地面地质资料和钻井或矿山地下资料,证明了盆地和裂谷中绝大部分断层是犁形断层,或者至少开始时具有犁形断层性质。 The fault surface is concave and concave, and gradually becomes deeper toward the depth. The plow-shaped faults are called Listric faults, and are called “shovel faults”, “plow faults” or “plow faults” in China , Also known as “tilt fault”, “Kei-shaped fault”, “half-cut”. As early as 1904, Suess proposed the concept of a plow fault. Cloos and Mohr et al. Also experimented with plowing faults. In recent years, artificial seismic surveys, a large number of reflected seismic data, surface geological data, and borehole or mine subterranean data have been widely carried out in various parts of the world. It is proved that the vast majority of faults in the basin and rift are plow-shaped faults or, at least initially, Fracture properties.
