This chart gives an overview of the international chronostratigraphic units,their rank, their names and formal status. These units are approved by the International Commission on Stratigraphy (ICS) and ratified by the International Union of Geological Sciences (IUGS). The Guidelines of the ICS (Remane et al., 1996,The utility of ICS International Chronostratigraphic Charts (ICS Charts) relies on the accuracy and precision of reported geochronologic dates and their relationship to the bases of global chronostratigraphic units. However, an examination of some early Paleozoic dates (i.e., Cambrian-Ordovician boundary and lowest Ordovician) on the ICS ...International Chronostratigraphic Chart. In addition, ICS is collaborating with the IUGS Commission on Geoscience Information (CGI) as it develops GeoSciML as an . 5 interchange format for geoscience data. ICS subcommissions are traditionally affiliated with a considerable number of IUGS and IGCP activities. For example, ICSTo date, approximately two-thirds of the Phanerozoic chronostratigraphic boundaries have been defined in terms of the Global Standard Boundary Stratotype Section and Point (GSSP) concept in the International Chronostratigraphic Chart. However, in practice, almost all definitions and correlations of these boundaries are controversial, and some of the definitions are indeed questionable.The International Commission on Stratigraphy (ICS) has a long tradition of producing international charts that communicate higher-order divisions of geological …The different colours of spots on the map correspond to various geological stages of the International Chronostratigraphic Chart. This is displayed in disc-shaped form in the lower righthand corner of the map and it can be manually hidden. The interactive experience has been enhanced on a friendly interface.Chronostratigraphy is the branch of stratigraphy that studies the ages of rock strata in relation to time . The ultimate aim of chronostratigraphy is to arrange the sequence of deposition and the time of deposition of all rocks within a geological region, and eventually, the entire geologic record of the Earth .Chrono Strat Chart 2012 - Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online.
