3.3.4 Supersuite (Oversuite)

3.3.4.1 A supersuite is a lithodemic unit comprising two or more suites or complexes having a natural relationship to one another, either in the lateral or vertical sense.

3.3.4.2 Supersuite is a formal lithodemic unit ranking next above suite.

3.3.4.3 A supersuite has a regional extent.

3.3.4.4 A supersuite is mappable at the surface and traceable in the subsurface using geological and geophysical methods.

3.3.4.5 A supersuite may consist of lithodemic units belonging to the same and/or different class(es) of rocks.

3.3.4.6 A supersuite is only named formally, this being done in accordance with the "general rules for naming and defining geological units" (Chap. 2). The name consists of a geographical name (or an alternative name on the continental shelf) between the words "the ... Supersuite".

3.3.4.7.a Supersuite corresponds in rank to supergroup in the lithostratigraphical classification system.

3.3.4.7.b A supersuite should only be erected after a thorough assessment of whether it will have any practical value. Considerable mapping and scientific documentation is required prior to its erection.

3.3.4.8 Examples: So far no supersuite has been defined on Norwegian territory. It could, for example, be feasible to use the term for the magmatic lithodemes of the Oslo Region, and for major assemblages of plutonic lithodemes in both the Precambrian basement (grunnfjellet) and the Caledonian mountain chain.

3.3.4.9 Key reference: NACSN (1983).
