  • The Jiayuguan active fault is situated near Jiayuguan City.It is closely related to the Jiayuguan-Wenshushan uplift (which is one of the three uplifts in the Hexi Corridor:the JiayuguanWenshushan uplift in the western part of the Hexi Corridor, Yumushan uplift in the central part of the Hexi Corridor and Dahuangshan uplift in the eastern part of the Hexi Corridor)and is also a component part of the northern Qilian marginal-Hexi Corridor active fault system.The fault strikes N320°W and extends linearly for 20 km.It cuts the pre-Cretaceous, Cretaceous, Neogene and upper Pleistocene.In section, the southwestern block of the fault moves up, while the northeastern block moves down; in plan, it is marked by apparent right-lateral strike-slip motion.Five phases of neotectonic movement took place along the Jiayuguan fault during the latest Pleistocene to Holocene, i.e.at 4.3-4.5, 12.9-14.0, 20.0-23.2, 35.5-45 and 58.1 ka BP.The faulting was dominated by stick-slip movement and shows the distinctive characteristics of paleoearthquakes.
