Description

En smal kismineralisering av liten utstrekning er undersøkt med et lite sprett (<1 m3 tipp). Her sees oppimot 20 cm mektig finkornig, finbåndet, semimassiv magnetkis og litt kobberkis i silifisert grønnskifer. Inkludert over- og underliggende sulfid-impregnasjon er samlet mineralisert mektighet ca. 40 cm. Sidestein er en finkornig, grågrønn skifer. Det er også observert et smalt, maksimalt 10 cm mektig, semimassivt magnetkislag 200 m lenger sør, på omlag samme nivå. Det opptrer også en høyereliggende rustsone, blottet bl.a. ca. 100 m NNØ for det lille skjerpet, hvor det er 20-30 cm mektig magnetkis-impregnert skifer med båndet kvartsitt over og under.

Caledonian sulphide deposits and minor iron-formations from the southern Trondheim region, Norway.

Abstract:

Within the southern and central parts of the Trondheim region of the Norwegian Caledonides a great number of small, stratabound cupriferous pyrite deposits are confined to mafic metavolcanics of the Gula, Støren and Fundsjø Groups of the Lower Palaeozoic succession. The deposits occuring within, or in close contact with the metavolcanics are characterized by their association with minor manganiferous oxide/silicate iron-formations - better known as "vasskis" ore type - within the metamorphic low-grade areas. The iron-fprmations of the metamorphic higher grade terrains on the other hand, which are extensively developed within the Gula Group, are mostly of a pyrrhotitic sulphide/silicate type and sulphurization processes are thought to have played an important role during the metamorphism. The pyrite deposits occurring adjacent to the metavolcanics bear no relationship to the iron-formations. They are embedded in pelitic, often carbonaceous assemblages (Gula Group) or within tuffitic members of the volcanogene Støren Group, and they are thought to represent re-sedimented (reworked) deposits. The pyrite deposits display varying degree of metamorphic reconstitution and a tectonic control has apparently determined their disc- or ruler-shaped morphology.
