通过对织金、金沙地区早寒武世高分辨层序地层分析，认为研究区早寒武世织金、金沙早寒武世高分辨层序地层总体上识别出海平面向上变浅的2个大的沉积序列，织金剖面进一步识别出4个次级层序，金沙剖面进一步识别出5个次级层序。对研究区代表性剖面含磷岩系层序地层的分析，认为生物碎屑滩相最有利海相磷块岩的产出，其次为淹没台地相与生物碎屑滩相的过渡相；研究区海相凝块岩由富磷酸盐析出磷而产出，富磷酸盐的析出受控于海水酸碱环境。

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.
