Study on Geological Model of Cycle Stratigraphic Period Identification Based on Wavelet Transform
The strata record abundant geological time information.Milankovitch cycles in the strata can be identified by the unique time ratios of the age difference period,the axis slope period,the short eccentricity period and the long eccentricity period when the strati-graphic age data are lacking or the accuracy is very low.Based on this periodic proportional relation,a sine or cosine periodic function with the same proportional relation is constructed to represent the signal with Milankovitch cycles,and then studying on the Milankovitch cycles.
