     The Gumudi anticline is a typical and complex structure unit of superimposed fault-related folds in the piedmont of northern Tianshan Mountains, with strong deformation. Based on the analysis of 2D seismic profile crossing Gumudi anticline, constrained by the surface outcrop and drilling-revealed structural appearances, this paper presents the shallow folds shapes by fault-related folds analysis, speculates the deep structural styles according to the fold-fault quantitative relationship, in geometry, and then develops the reasonable structural model for Gumudi anticline, by which reappears the structural deformation procedures through kinematic recovery of this anti- cline. The study indicates that Gumudi anticline is a nearly east-west trending anticline and its tectonic deformation took place from late Yanshan movement to middle-late Himalayan movement. The eastern part of the shallow structures in Gumudi anticline is a front faulted- extensional anticline, toward the west it transits to nearly two-side symmetrical detachment-like faulted-extensional anticline, and the deep structure is a dual-stacking structure with the roof Xishanyao coal seam of the Middle Jurassic and the floor Lueaogou formation of Permian.
