Abstract：The trough-like folds and thrust are well developed in Southeast Guizhou The characteristics and origin of the structure in Southeast Guizhou are studied by analyzing the planar distribution of the folds and the strata, the nature and occurrence of the fault, the detachment beddings and the interpreted and restored seismic cross-sections. The results show that besides the depth of decollement and the denudation difference, the formation of the trough-like folds is also controlled by the distance from the nappe, the occurrence of the thrust, the length scale ratio of flat to ramp, the breakthrough ways of the fault and the multidecollement Combining with the regional tectonic evolution and the nappe distance, the geometry and the kinematics models of the trough-like folds structural style are established in Southeast Guizhou, which are mainly controlled by the minor scale of flat to ramp, various ways of thrust breakthrough and multi-decollement.
