- The Quaternary period has been characterized by several glacial periods, when ice sheets covered vast areas of continents. These glaciations are classified as the Pleistocene and include the present interglacial time-period, the Holocene. The Quaternary began approximately 2.6 million years ago with the onset of Northern Hemisphere glaciation1234. It is part of a larger sequence of glacial and interglacial periods known as the Quaternary glaciation4. Quaternary geology studies the processes and deposits that developed during this period5.Learn more:✕This summary was generated using AI based on multiple online sources.

During and between these glacial periods, rapid changes in climate and sea level have occurred, and environments worldwide have been altered.www.britannica.com/science/QuaternaryThe Quaternary covers the time span of glaciations classified as the Pleistocene, and includes the present interglacial time-period, the Holocene. This places the start of the Quaternary at the onset of Northern Hemisphere glaciation approximately 2.6 million years ago (mya).en.wikipedia.org/wiki/QuaternaryThat phase is known as the Quaternary glaciation, and was marked by more or less extensive glaciation. They first appeared with a dominant frequency of 41,000 years, but after the Mid-Pleistocene Transition that changed to high-amplitude cycles, with an average period of 100,000 years.en.wikipedia.org/wiki/Timeline_of_glaciationThe LGP is part of a larger sequence of glacial and interglacial periods known as the Quaternary glaciation which started around 2,588,000 years ago and is ongoing. The definition of the Quaternary as beginning 2.58 million years ago (Mya) is based on the formation of the Arctic ice cap.en.wikipedia.org/wiki/Last_Glacial_PeriodQuaternary geology is the branch of geology that study developments from 2.58 million years ago to the present. In particular, Quaternary geology study the process and deposits that developed during the Quaternary, a period characterized by glacial - interglacial cycles.en.wikipedia.org/wiki/Quaternary_geology
