Abstract Palaeoclimatic data (thickness variations in the Elatina Formation periglacial varves in the Flinderes Range, South Australia) with a spatial resolution of about one year and a time period of about 1334 years dated to the Marinoan glaciation, 680 Myears ago (late Precambrian), were studied in order to reveal quasiperiodic variations in climate processes in the past. Seven hidden periodicities, i.e., 12, 22, 24, 26, 104, 157, and 316 years, were revealed with a significance level of amplitudes in the framework of the polyharmonic model from 4σ up to 16σ. It was found that some of the detected periodicities were similar to the current solar activity cyclicity.
