Metamorphism of ultramafic rocks in the Central Scandinavian Caledonides

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;Special publication; No.3;86-95 pages

Abstract:

Lenses and boudins of ultramafic rocks in the Central Scandinavian Caledonides (CSC) represent parts of dismembered ophiolite sequences and fragments of sub- continental upper mantle. The metaperidotites are isofacial with the metamorp- hic envelope, usually metasediments but in place also metagranitoids. Metamorphic assemblages in metaperidotites of the CSC, together with additional geological constraints, define a regional metamorphic gradient of prograde metamorphism which passes through the approximate PT-coordinates (in C and kbars): 400/4, 500/6, 600/8, 700/9. The sequence of prograde metamorphic assemblages is (with increasing temperature): antigorite+brucite, antigorite+ forsterite, forsterite+talc, forsterite+enstatite+chlorite, and forsterite+ enstatite+green spinel. The maximum temperature was not sufficient to replace calcic amphibole by calcic pyroxene. Pargasite overgrowth on earlier tremolite demonstrates the prograde nature of the metamorphism. Most of the ultramafic rocks probably represent progresively metamorphosed serpentinites (mantle-or crustal serpentinites?). The regional distribution of assemblages in the ultramafic rocks of the CSC defines a regular pattern which cross-cuts the nappe boundaries of the area.

En vurdering av mineralske ressurser i Skjerstad kommune, Nordland

;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.87.022;21 pages

Abstract:

Det er som grunnlag for vurdering av mineralske ressurser og Skjerstad sammenstilt berggrunnsgeologisk kart over kommunen i M 1:50 000. På dette er alle registrerte malm- og industrimineralforekomster avmerket. Det er gitt en vurdering av forekomstene og potensiale i kommunen. Det anbefales å gjøre et forprosjekt for å undersøke mulighetene for wolfram, platinagruppens elementer i tilknytning til nikkelmineraliseringer, kvarts, kalkstein/dolomitt og glimmer.
