The Norwegian Committee on Stratigraphy was established in 1982 by the Norwegian Council of Geology. In Article 1 of the mandate the committee was authorized to "work out and present a guide on stratigraphical procedure and nomenclature in Norway". The present Code, resulting from this work, should be used for classifying and naming geological units in Norway, on the Norwegian continental shelf and in Norwegian territories and claims in the Arctic and Antarctic. The general chapters deal with definitions of basic concepts, such as the meaning of `formal` and `informal` units, rules for naming geological units and how to write names in Norwegian and English, as well as procedures for erecting, registering and changing the definition, rank and name of formal units. Emphasis has been placed on defining and naming subsurface units on the continental shelf. The Code expresses the principles of the International Stratigraphic Guide of 1976 (ISSC 1976) and has also adopted several of the stratigraphical categories introduced in the North American Stratigraphic Code (NACSN 1983). It also include 6 new formal categories of geological units: geomorphological and structural form units, linear structural units (lineaments), planar structural units (joints, fractures, faults), morphostratigraphical units, tectonostratigraphical units and diachronous units defined by deformation events. Climatostratigraphical units are included in the category of diachronous units. The sections dealing with the 17 categories of geological units include basic definitions and terminology in English and Norwegian, the rank and position of the units in the classification systems along with their dimensional properties, mappability and methods used in identifying them, material or time content and other properties, nomenclature principles, comments on their variability and their relationship to other units, examples and key references.
