【Abstract】 A transform fault is essentially a displacement fault whose terminal parts are adjusted by other tectonic types and whose displacement component is absorbed by other structures intersected with the terminal parts at high angles or met at right angles. The main elements of a transform fault are the steep dipping displacement faults and the adjusted structures intersected with the terminal parts at high angles. According to the combination of the tectonic features formed by the two ends of the displacement fault and the structures intersected with the terminal parts, the transform fault can be divided into three types, including the adjusted transform fault of extensional normal fault, the adjusted transform fault of compressive fold and thrust fault, and the compound transform fault. The traditional Altyn fault is the adjusting fault of the compression deformation of the Western Kunlun and Northern Qilian mountains of the northern margin of the Qinghai Tibet Plateau since Cenozoic.更多还原
