Power-spectrum analysis of two 'varved' argillites in the Huronian Cobalt Series (Precambrian) of Canada



Power-spectrum analysis of two 'varved' argillites in the Huronian Cobalt Series (Precambrian) of Canada



Journal of Sedimentary Petrology 35(4): 877-886



Thickness of varve couplets were measured at two outcrops and the distribution of thicknesses analysed by power- (variance-) spectrum statistics. No significant periodicity was found relating varve thickness to the sun-spot cycle or other cycles.
