Through the analysis of sequence stratigraphy of Zhijin and Jinsha area of early cambrian high resolution, this paper suggests that the study area of the early cambrian in Zhijin, and the early cambrian high resolution identifies the sea level upward of two large sedimentary sequence of shallow stratigraphic sequence in general, Zhijin section further identifies the four secondary sequences, and Jinsha profile further recognizes the five secondary sequence. Analysis of the sequence stratigraphic profile of phosphorus rock in this area represents the bioclastic shoal facies, and the most favorable marine phosphorite output, followed by the submerged platform facies transition shoal phase; marine clot rocks in the study area are produced by phosphorus acid salt of phosphorus, and rich phosphate precipitation is controlled by seawater pH environment.
