Prior to the Quaternary glaciation, land-based ice formed during at least four earlier geologic periods: the late Paleozoic (360–260 Ma), Andean-Saharan (450–420 Ma), Cryogenian (720–635 Ma) and Huronian (2,400–2,100 Ma).
12 paź 2020 · The latitudinal integration of land ice volume distribution across the Quaternary (Fig. 2b) clearly shows that northern hemisphere land ice was mostly situated north of 65°N before the MPT, and...
Once a continuous high ice-cap ridge is formed, a warmer and/or drier climate than today is required to cause deglaciation. There are three specific conclusions arising from this work: The growth and decay of the Patagonian ice cap illustrates non-linear behaviour due to topographic effects.
This article summarizes the geological and paleoceanographic evidence of the Quaternary ice sheets, with emphasis on the chronology of glacial-interglacial cycles and the geographic distribution of the ice sheets.
1 sty 2022 · The reason why orbital cycles influence the genesis of ice ages in the Quaternary may be explained by the distribution of the planet’s relief and the configuration of the continents in the prelude to the Quaternary.
24 gru 2014 · In these special circumstances, a great cap of ice will form that refrigerates the enclosing waters, which then sink into the depths and gradually fill the ocean basins from below.
