The Simulation Geologic Features and Forming Mechanism of the Salt Diapiric Structure of the Wensu Canyon in Xinjiang

Abstract

Based on the regional geological surveying and the contrary with the resemble salt diapiric structure at home and abroad, this paper indicates that the Ochirbat salt diapiric structure in the Canyon of Xinjiang Wensu County has typical and integral spatial pattern and huge body. By analyzing its forming mechanism and its evolution stages, we conclude that plasticity of the plastic salt deposited for a long time becomes very bigger under the different gravity pressures supported such as different deposition and compaction and goes over top-storey, and flows out along its surface through a few stages of the salt-pillow, saltanticline, salt diapiric, overcrowd and strength, which took place in the course of the Himalayas tectonic movement. All in all, the Ochirbat salt diapiric structure in the Canyon of Xinjiang Wensu County has unique and scientific characteristic whether from the space form or mechanism of formation. There are very precious values of remains protection and geological expedition in the fields of science and investigation. In addition, the salt diapiric structure is a better geological structure in which there is plenty of oil and has very important economic development value.
