Locality type:Complex
Köppen climate type:Dfb : Warm-summer humid continental climate


Famous for its rare volcanic/meta-volcanic rocks:

Carbonatites: søvite (coarse-grained calcite carbonatite), rødberg (altered carbonatite with hematite stained granular calcite, dolomite and sometimes ankerite), rauhaugite (dolomite carbonatite), ringite (coars-grained carbonatite containing aegirine and alkali-feldspar).
Lamprophyres: damkjernite (melanocratic nepheline lamprophyre).
Ijolites: melteigite (melanocratic nepheline ijolite), hollaite (calcite-melteigite, consisting of pyroxene (55%), calcite and nepheline).
Other rocks: fenite (metasomatic rock composed of alkali feldspar, sodic pyroxene and/or alkali amphibole, sometimes monomineralic alkali feldspar rock), vibetoite (pyroxenite containing aboundant Ti-augite and hornblende with biotite, primary calcite, and occasional albite and nepheline).

Many of the rocks were first described by W. C. Brøgger in 1921.
Most areas of the complex are now protected because of its value to science, and collecting is prohibited!

Geochronology

Mineralization age: Ediacaran : 568 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
