The tectonic response of the Ordos Basin to Indosinian movement mainly occurred in the southwestern part of the basin due to the Late Triassic collisional Qinling orogeny to the south. The orogeny resulted in intense uplift and exhumation of the southwestern section of the Ordos Basin, where the upper and middle parts of the Upper Triassic Yanchang Formation were exhumated and the magnitude of exhumation progressively decreased to the northeast (Liu Chiyang et al., 2008). However, little attention has been paid to the influence of Indosinian movement to the northern Ordos Basin. In this study, stratigraphic observations and new apatite fission track (AFT) data are integrated to characterize the effect of Indosinian movement in the northern Ordos Basin.
