Abstract: Based on abundant geological and geochemical data, the salt lake sedimentary characteristics of the Lower Ganchaigou Formation of Oligocene were studied to identify the major rock types and discuss the controlling factors of complex lithofacies, so as to restore the paleo-sedimentary environment and establish the sedimentary models. Salt lake can be divided into two types of sedimentary environments including basin margin and intra-basin, and five types of sedimentary facies zones are developed. The beach slope facies zone, steep slope facies zone and gentle slope facies zone are developed in the basin margin sedimentary environment, and the underwater high facies zone and the profound water facies zone are developed in the intra-basin sedimentary environment. There are three evolutionary stages from the bottom to the top of the upper section of the Lower Ganchaigou Formation:semi-salt lake, salt water lake, and salt lake, corresponding to three lithological associations of carbonate rocks and calcareous sandstone, anhydrite-rich carbonate rocks and mudstones, and thick-bedded salts and thin-bedded carbonates. The distribution of sedimentary lithofacies is controlled by the differences of chemical, biological and physical sedimentation, and the main controlling factors of sedimentation are climate, paleo-geomorphology,and tectonic movement.
