Quaternary geology is the branch of geology that study developments from 2.58 million years ago to the present. [ 1 ] [ 2 ] In particular, Quaternary geology study the process and deposits that developed during the Quaternary , a period characterized by glacial - interglacial cycles.
Quaternary science is the subfield of geology which studies the Quaternary Period commonly known as the ice age. The Quaternary Period is a time period that started around 2.58 million years ago and continues today. [1] [2] This period is divided into two epochs – the Pleistocene Epoch and the Holocene Epoch.
The Quaternary (/ k w ə ˈ t ɜːr n ə r i, ˈ k w ɒ t ər n ɛr i / kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon.

The Quaternary glaciation produced more lakes than all other geologic processes combined. The reason is that a continental glacier completely disrupts the preglacial drainage system . The surface over which the glacier moved was scoured and eroded by the ice, leaving many closed, undrained depressions in the bedrock.
The Quaternary Period, the Cenozoic Era geologic time unit from the end of the Pliocene Epoch, roughly 1.8−1.6 million years ago, to the present day. The Quaternary has 2 geologic/geochronologic subdivisions, the Pleistocene and the Holocene Epochs .
This list is divided first into the geologic eras of the Phanerozoic (the Cenozoic, the Mesozoic, and the Paleozoic) and then into the geologic periods of each era.Each period is marked below the era bar on top of its subdivided epochs and stages.
