根据成岩作用现象及划分标志，本区侏罗系地层可划归于埋藏成岩阶段的早成岩B亚期，晚成岩A亚期及表生成岩期。
It is evidently concluded that Jurassic rocks in this area have undergone burial diagenesis, and can be classified as B sub-period of eogenetic, A sub-period of telogenetic and epidiagentic stages.
其中建设性成岩作用主要是表生岩溶作用、埋藏溶解作用，破坏性成岩作用主要为各期的充填作用，对孔隙破坏性最大的胶结物是亮晶方解石。
The constructive diagenesis are mainly epigenic karstification and burial dissolution. The destructive diagenesis are filler in each periods, the most devastating cement to porous is sparry calcite.
