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).
1 sty 2024 · In that sense, the identification of water ice in the polar caps, viscous flow forms, and near-surface regolith of Mars, together with associated morphological analogues of Quaternary cryogenic landforms on Earth, offers immense potential to understand planetary environmental evolution in the solar system more broadly.
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...
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.
A defining feature of the Quaternary is the build-up and decay of continental-scale ice sheets in the high middle latitudes of the northern hemisphere and in Europe. The current interglacial period began at the start of the Holocene 11,700 years ago.
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.
