Owing to Yanshanian and Himalayan movement, a series of down faulted basins were formed in Late Cretaceous-Paleogene, when Paleocene halite of salt lake deposition was formed in Shashi Formation of Jiangling Depression. The understanding of paleoclimate has important significance for the study of the evolutionary phase of salt lake, the halite origin and the prediction of geological stages and strata of potash salts.
