  • Sedimentary environments of Tertiary saline lake and clastic depositional system in Luntai fracture-uplift of Tabei uplift, Tarim basin are studied in detail. In the study area, the depositional patterns were dominated by a rid and semi-arid climate. Two suits of reservoir and seal, respectively Suweiyi Fm. of Pa-leogene and Jidik Fm. of Neogene developed in such conditions, so that their sedimentary and reservoir characteristics had close correlation with the saline deposits, especially the widely distributed anhydrite in this area.

The sedimentary charac-teristics are summarized in this paper based on the relationship between different structures in anhydrite and environments as the breakthrough point, simultaneously combined with element geochemistry. Five kinds of sedimentary facies were recognized as alluvial fan, sandsheet , ephemeral saline lake, perennial saline lake, ephemeral river and flooded plain, among which the key reservoir sandsheet was subdivided into common, finesorted and gypsificated ones.

Abstract: Sedimentary environments of Tertiary saline lake and clastic depositional system in Luntai fracture-uplift of Tabei uplift, Tarim basin are studied in detail. In the study area, the depositional patterns were dominated by a rid and semi-arid climate. Two suits of reservoir and seal, respectively Suweiyi Fm. of Pa-leogene and Jidik Fm. of Neogene developed in such conditions, so that their sedimentary and reservoir characteristics had close correlation with the saline deposits, especially the widely distributed anhydrite in this area. Anhydrite was classified into ten sorts according to its occurrence. The sedimentary charac-teristics are summarized in this paper based on the relationship between different structures in anhydrite and environments as the breakthrough point, simultaneously combined with element geochemistry. Five kinds of sedimentary facies were recognized as alluvial fan, sandsheet , ephemeral saline lake, perennial saline lake, ephemeral river and flooded plain, among which the key reservoir sandsheet was subdivided into common, finesorted and gypsificated ones. In conclusion, the author summarized the depositional model of Suweiyi Fm.
