Paper Abstract

Computing of periodicities in Mars sediment time series has been successful following a spectral analysis method that first was elaborated and tested on terrestrial deposits. In this paper the terrestrial method will first be explained on basis of fossil soil stratigraphic sequences mainly obtained from loess deposits on the Loess Plateau of China and the smaller Loess Belt of Northern France and Belgium. The computation method is called ExSpect: an Expert Spectral Analysis programme for cyclicity calculation. ExSpect was used for timespans and cyclicities of geological proxydata sets/time series behaving like acoustic signals. In applying this method on sediment time series of Mars image sediment sections a large cycle of 400Ka and two smaller ones of 4Ka and 9Ka (in Mars years) are computed like on Earth.
