Synopsis top ↑

In recent years the increasing volume and complexity of the work of the International Commission on Stratigraphy (ICS), a commission of the International Union of Geological Sciences (IUGS), has created a demand for procedural guidelines and for updating and reissue of the Statutes of ICS. The following Guidelines have been shown to the President and Secretary-General of IUGS but the Bureau of ICS are solely responsible for their content. The Statutes, however, constitute a formal directive document which has been ratified by the Executive Committee of IUGS in February 1986. The Commission is responsible for the coordination of international stratigraphy from the earliest part of the Archaen Eon through the Proterozoic and Phanerozoic Eons to the Recent and includes studies on all aspects of stratigraphy — physical, chemical and biological. A considerable part of these guidelines is devoted to the currently important topic for ICS of selection and definition of Boundary Stratotypes. It must not be assumed, however, that other aspects of stratigraphy are not of great importance too and developing studies in future years may considerably change the present emphasis and require further guide- lines to be drawn up. These guidelines are not necessarily retrospective and do not automatically affect decisions already approved and made by ICS and ratified by IUGS. The International Stratigraphic Guide (HEDBERG, 1976), prepared and published by the Subcommission on Stratigraphic Classification of ICS, contains valuable discussion and recommendations but it was never adopted by ICS as a statutory policy document; it is now being revised. These Guidelines and Statutes prepared by the Bureau of ICS should be used in preference when and where there is a difference between them and the International Stratigraphic Guide.
