| Abstract: | Firstly, the carbonate rocks of Lower Middle Triassic in Shimen are divided into twenty one types of lithofacies. Then their sedimentary conditions are analysed. Secondly, on the basis of lithofacies analysis, nine kinds of lithofacies associations are established, followed by the discussion of the sedimentary environments of lithofacies associations. Thirdly, four sorts of shallowing upward sedimentary cycles and the characters of the evolution, the major sedimentary stratum of evaporites are summarized. |
