6.1 Recommended stratigraphic unit names

The table below contains all 234 stratigraphic unit names which form part of the Upper Palaeozoic to Cenozoic schemes recommended herein. The names are listed in alphabetical order according to their English form. The Norwegian spelling follows modern Nynorsk orthography and has been approved by the Norwegian Language Council. The ID numbers help identifying the respective units in the lexicon text, stratigraphic type sections, maps and other tables. The table further indicates the formal or informal status of the units. The right column shows the superior stratigraphic unit to allow a quick check where a respective name belongs.

6.2 Type sections and type localities

The table below contains all 234 stratigraphic units which form part of the Upper Palaeozoic, Mesozoic and Cenozoic schemes, respectively, recommended herein. The names are listed in the order of their ID numbers used to identify the units in the lexicon text, stratigraphic type sections, maps and other tables. In the type section/area column, type areas without a definite type section are written in italics. Type sections are indexed according to their nature as explained here:

• Stratotype (S): The main type locality and section which presently defines the unit.
• Hypostratotype (H): The second or third type locality of a unit that documents major regional variations.
• Boundary stratotype (B): If a unit does not have a documented locality where both its base and its main body are sufficiently represented, the type locality for the lower boundary is defined by the boundary stratotype.
• Unit stratotype (U): If a unit does not have a documented locality where both its base and its main body are sufficiently represented, the type locality for the main body is defined by the unit stratotype.

UTM coordinates are given for all type sections with the accuracy of 100 m, using the ED50 system which is also used on Norsk Polarinstitutt’s geological maps. For small type areas, UTM coordinates are indicated for the approximate centre of the area. For larger type areas, no coordinates are provided.

References are given to the author(s) responsible for the presented stratigraphic log (if not available, for the presently valid description) of the respective type section. This is not necessarily the first stratigraphic log or description of the respective unit. See lexicon text in Chapters 2, 3 and 4 for further references. For type sections with unpublished references, the present volume should be referred to as the first published source.
