Working Groups and Task Group of the International Subcommission on Cambrian Stratigraphy. The Cambrian Subcommission has devised and approved a plan for subdividing the Cambrian System into four series and 10 stages.

Map symbols are in parentheses.commission held in February-March 2002, which ended with a 82,4 percent agreement and thus the approval of the proposal. The proposal was submitted to the International Commission on Stratigraphy and was accepted by the ICS bureau at the meeting in Urbino, Italy, mid-June 2002 and passed for the final ratification.The geologic time scale is the stratigraphic history of the Earth.Stratigraphy, also called chronostratigraphy is the ordering and analysis of the layers of the Earth (also called strata) based chronological dating techniques and the layers' positions relative to each other.Geologic time begins approximately 4.6 billion years ago, shortly after when the Earth began to form.

The GSSP occurs in a succession of dark gray to black limestones (lime mudstones, or calcimicrites and calcisiltites) and fine-grained argillaceous limestones interbedded with lenses of fossil rich limestone (calcisiltie). Lejopyge laevigata first appears in the lower part of a 82 cm thick layer of dark gray, thinly laminated calcisiltite ...The Anthropocene Working Group (AWG) is an interdisciplinary research group dedicated to the study of the Anthropocene as a geological time unit.It was established in 2009 as part of the Subcommission on Quaternary Stratigraphy (SQS), a constituent body of the International Commission on Stratigraphy (ICS). As of 2021, the research group features 37 members, … ….
