5 cze 2012 · This chapter focuses on the major subdivisions and events in the terrestrial sequences of the Pleistocene and Holocene, with correlations to the marine record. Current proposals for formal subdivision are outlined.
The best-known are those that occurred from the time of the last interglaciation, about 125,000 years ago, to the present. The growth of large ice sheets, ice caps, and long valley glaciers was among the most significant events of the Pleistocene. During times of extensive glaciation, more than 45 million square km.
17 mar 2005 · Together, the Pleistocene and Holocene make up the Quaternary System (chronostratigraphy) and Period (geochronology), which extends from 2.58 million years ago (Ma) to present (Gibbard et al ...
Two major types of subdivisions have been proposed for the Pleistocene Series. A standard subdivision at stage level has been advocated by workers based on sections in elevated shallow-marine sediments in Italy.
