International Subcommission on Stratigraphic Classification of IUGS International Commission on Stratigraphy - International Stratigraphic Guide - AnAbridged Version

Effective communication in science requires accurate and precise internatio nally acceptable terminology and procedures. The Abridged Version of the In ternational Stratigraphic Guide, like the Guide itself, was developed to pr omote international agreement on principles of stratigraphic classification and to develop an internationally acceptable stratigraphic terminology and rules of procedure in the interest of improved accuracy and precision in i nternational communication, coordination, and understanding. It is not a re vision of the Guide but a short version that omits history, explanatory tex t, and exemplification, the glossaries and the bibliography.
