GEOPHYSICAL STUDY OF SEDIMENTARY CYCLES

Analysis on sedimentary cycles is very important in the academic study of stratigraphy,petroleum exploration and exploitation.The principle used to grade cycles and the anatomy of inner cyclic structure are basic matters in the study of cyclicity.Geophysical data,as the representations of lithology and physical properties,embrace much information related to sedimentary cycles.Using geophysical methods to extract corresponding information will greatly promote the quantitative study of sedimentary cycles.Wave process analysis,spectrum analysis,time-frequency analysis and other geophysical methods have been applied to this field.Practice proves that,geophysics study is an effective means of sedimentary cycles research.
