digenesis การใช้

• Under the guidance of the theories of sedimentation , paleontology , stratigraphy , reservoir geology and digenesis , synthetically applying the methods of the conjunction of spot - line - surface , macro - microscopic and field - indoor , there is a comprehensive study for the upper permian series in stratum , rock , sedimentary facies and diagenesis , especial for the type and characteristics of sedimentary facies , in the paper . based on the above , the vertical evolutionary model of the sedimentary environment is explained by the study of the elevation profile and transverse profile and the regional geological characteristics
