Gypsum salt rocks of the Paleogene occur in the surface outcrops of western Kuqa depression in Tarim basin. This article pres-ents the overall salt structure, deformation and migration characteristics of the salt sheet, salt wall and salt raft by field trip and remote sens-ing satellite image interpretation. The deformation and migration direction of salt sheet are mainly controlled by gravitational detachment, and its shape is affected by the structural setting. The salt raft is resulted from the gravitational detachment also, and the salt wall is formed by difference loading effect which creates diapir into the surface. At the same time, the weather and topography play an important role in the migration of the gypsum salt rocks, causing the plastic deformation, crawling folds and inner salt folds.
