| 释义 |
In the geologic time scale, the Greenlandian is the earliest age or lowest stage of the Holocene epoch or series, part of the Quaternary.[1][2] It is one of three subdivisions of the Holocene. The lower boundary of the Greenlandian Age is the GSSP sample from the North Greenland Ice Core Project in central Greenland (75.1000°N 42.3200°W).[3] The Greenlandian GSSP has been correlated with the end of Younger Dryas (from near-glacial to interglacial) and a “shift in deuterium excess values”.[3] The age began 11,700 years prior to the year 2000.[4] The age was officially ratified by the International Commission on Stratigraphy in July 2018 along with the Meghalayan and the Northgrippian.[1] References1. ^1 {{cite web |last1=International Commission on Stratigraphy |title=ICS chart containing the Quaternary and Cambrian GSSPs and new stages (v 2018/07) is now released! |url=http://www.stratigraphy.org/index.php/ics-news-and-meetings/120-ics-chart-containing-the-quaternary-gssps-and-new-stages-v-2018-07-is-now-released |accessdate=15 July 2018}} {{Geological history|p|m}}{{geochronology-stub}}2. ^{{cite web |last1=Cohen |first1=Kim Mikkel, David A.
