The International Commission on Stratigraphy(ICS)aims to define precisely aglobal standard set of time-correlative units(systems,series,and stages)and provides the International Chronostratigraphic Chart,which is considered as an international standard for expressing geological knowledge.The official website of the ICS provides the stratigraphic information service for the ICS,especially maintaining the updates and release of the International Chronostratigraphic Chart.The ICS chart is subject to revision due to three major reasons,new GSSP was ratified,numerical age was revised,or the subdivision of a chronostratigraphic unit was changed and formally approved.Since 2013,the ICS chart is more occasionally revised,1~2times each year,to demonstrate the latest achievements of the chronostratigraphic research.The Chinese stratigraphers devoted themselves to the international chronostratigraphic research and the introduction and translation of the ICS chart.Here we release the Chinese version of the latest ICS chart,the"2015/01"version.
