The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing.
During the 2.5 million years of the Pleistocene, numerous cold phases called glacials (Quaternary ice age), or significant advances of continental ice sheets, in Europe and North America, occurred at intervals of approximately 40,000 to 100,000 years.
In the Southern Hemisphere, the Patagonia Ice Cap developed in the southern Andes, and ice caps and larger valley glaciers formed in the central and northern Andes. Glaciers also developed in New Zealand and on the higher mountains of Africa and Tasmania, including some located on the equator.
Pleistocene Epoch, earlier and major of the two epochs of the Quaternary Period of Earth’s history, an epoch during which a succession of glacial and interglacial climatic cycles occurred. It ended 11,700 years ago. It was preceded by the Pliocene Epoch and followed by the Holocene Epoch.
16 sie 2019 · Our reconstructions illustrate pronounced ice-sheet asymmetry within the last glacial cycle and significant variations in ice-marginal positions between older glacial cycles.
28 lut 2022 · The Pleistocene epoch lasted from about 2.6 million to 11,700 years ago and included the last ice age, when glaciers and giant megafauna dominated the landscape.
14 mar 2024 · A revised stratigraphy the Lower and Middle Pleistocene in southern Poland is presented, based on geological evidence from key sites, better constraints on the number and age of Scandinavian ice sheet advances, and the stratigraphic setting of the interglacial sequences.
