Instructions for filling-in the registration form
1. All named geological units, formal (F) and informal (I), are to be registered. (For definition of formal and informal units, see "Regler og råd for navnsetting av geologiske enheter i Norge" by NSK, Norsk Geologisk Tidsskrift 66, (Suppl. 1) pp. 1-96, and/or "Rules and recommendations for naming geological units in Norway" by NSK, Norsk Geologisk Tidsskrift, Vol. Suppl 1) pp. 1- .) In the case of already established units the original spelling of the name is used. Any new, official spelling of the geographical name in question is to be put in brackets. Geographical names used for newly proposed units should be on an official Norwegian map. The category, rank and status (formal and informal) of a unit are determined according to the guidelines in the Code. Any doubts concerning status are decided by NSK.
Key for unit categories:
Biostratigraphical units B
Deformational-diachronous units Dd
Diachronous units D
Geological form units Gf
Climatostratigraphical units (see also diachronous units) Kl
Chronostratigraphical units Kr
Lithodemic units Ld
Lithostratigraphical units L
Morphostratigraphical units M
Planar structural units Sgf
Linear structural units Sgl
Tectonostratigraphical units Ts
Others (see the Code) A
Examples of ways of filling-in the form: Barents Sea Group, L.F., Bjørnøy Basin, Gf,F., Kalak Nappe Complex Ts, F., Ekne discontinuity, Dd,I., Jørstad moraine, L, I.
2. Put X.
3. When revising the name and/or rank of a unit, the old name and rank is written here.
4. References that are as complete as possible are given here. If there is insufficient space, the title of the publication can be omitted. a) Reference for the first time the name is used for this unit in the literature. b) Reference for the current definition of the unit if that is not in (a). c) Reference for the description of the unit if that is not in a) or b).
5. a) The main geographical region is given according to the following key:
Norwegian mainland N Continental shelf K
Svalbard Sv Antarctic/Bouvetøya A
Jan Mayen JM Sweden S
Finland SF Soviet Union SU
Denmark DK Rest of Europe E
Great Britain GB
b) The name of the map-sheet is used for the 1:250 000 series;
field names are used for the continental shelf.
c) Use the number of the 1:50 000 map-sheet containing the unit. Other official maps may also be used; state which here.
d) To refer to the type locality or type section, use the UTM grid reference scheme or Greenwich degrees. In the case of the continental shelf use degrees as well as bore-hole number.
6. a) The name or designation of the geological region containing the unit, e.g. Bergen Arcs, Trondheim Region, southeast Norwegian basement area, etc., is put here.
b) If relevant, information should be given here concerning in which major tectonostratigraphical unit the unit is question is located.
7. For the geological description it is recommended that those guidelines given in the Code, that are relevant for the unit in question, are followed. In the case of lithological units, the name of the rock type is put first, followed by the description of features, including lithology, fossil content, deformation, metamorphism, etc., which characterize the unit. Boundary relationships to neighbouring units are to be described. If there is insufficient space, use a separate sheet.
8. a) When referring to geological periods use the following abbreviations:
Quaternary Q Palaeozoic Pz Precambrian PK
Cenozoic Cz Proterozoic Pt
Mesozoic Mz Archaean Ar
For other geochronological time units and abbreviations see the Statoil geological time scale (Appendix 3 in "Regler og Råd for navnsetting av geologisk enheter i Norge" by NSK, Norsk Geologisk Tidsskrift 66, (Suppl. 1) pp. 1-96, 1986.
More precise ages are written in full, e.g. 400 ± 20 my. Give the assumed age if an age determination is not available; write, for example, "assumed Devonian".
b) State whether the age represents the time the unit was originally formed (by deposition, intrusion, movement, deformation, etc.) or later metamorphism, tectonic movements or other disturbances of the original properties of the unit.
c) State whether the age determination derives from indirect techniques, the aid of fossils or radiometric methods. In the last-mentioned case, the actual method should be stated, e.g. Rb/Sr whole-rock.
9. The names of adjoining units, underlying, overlying, or adjacent to, preferably of the same rank as the unit described, are listed here.
10. If the unit forms part of a hierarchical classification system, the name of the unit that has the next higher rank and contains the unit in question, is given here. (This may, for example, be a group, if the unit is described as a formation; see the Code.)
11. The name(s) of other unit(s) with which the unit described has been correlated with, is(are) given here, along with appropriate reference(s). If necessary, use a separate sheet.
12. It is important to state whether the geographical name used as a proper name for the unit described has also been used for other geological units. (This is usually an undesirable practice; see the Code.)
13. "Other information" may be additional information that is of interest and importance for defining and describing the unit.
