Shanxi Formation is a set of paralic continental deposit,of which,fluvial,swamp and lacustrine facies alternatively presented regularly.

山西组为一套近海型的沉积,其中河流、沼泽及湖泊有规律地交替。

These basins were generally filled with upward fining and deepening sedimentary sequence that comprises nonmarine to marine, shallow marine to deep marine depositional systems.

盆地内堆积了从到海，从浅水到深水的各种积体系，组成向上变细和变深的充填序列。

Nonmarine sequence stratigraphy is used to analyze Jurassic depositional sequences in Tu-ha basin, and three sequences and one supersequence are divided in this paper.
