En 6 m lang og 1 m bred stoll med retning N170Ø finnes på nordsida av Svartfjellet. Den ligger i amfibolitt med nær kontakt til sandstein både over og under. Kvartslinser/-ganger som er opptil 10 cm brede finnes i taket i stollen. Disse er småfoldet men inneholder svært lite sulfider (prøve HO-19-130). Korte karbonatstrenger med litt svovelkis er observert i amfibolitten og disse skjærer også inn i kvartslinsene (HO-19-131/-132). Totalt sett er svært lite sulfid påvist i forhold til det arbeidet som er utført i skjerpet. Ved et mindre skjerp, en liten grop, som ligger 1300 m lengre østsørøst, finnes tilsvarende kvartslinser med noe svovelkis og kobberkis på sprekker og i druserom i foldet amfibolitt (prøve HO-20-134).

	The geology of the Komagfjord tectonic window of the Raipas suite, Finnmark, Norway.

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU; No.221;1-71 + kar pages

Abstract:

The report is based on four summers (1956-59) of field work in an area of approximately 860 km2. The area is located in western Finnmark, northern Norway, between 70 degrees 10' and 70 degrees 31' N latitude and 12 degrees 40' and 13 degrees 50' E Oslo longitude. The purpose of the investigation was to study the rocks within a hitherto mainly unexamined area of Precambrian rocks surrounded by Caledonian rocks. Portions of the area near the sea had been visited by a few geologists prior to the initiation of this investigation. It was therefor quite certain that the rocks were Precambrian in age and constituted a window in the Caledonides, but the size of the window was unknown nor had most of the window been studied geologically. This report establishes the Precambrian age of the rocks and delineates the boundaries of the window. The Precambrian rocks along the western coast of Finnmark were previously called the Raipas formation and known to outcrop in (at least) two windows. As this report differentiates seven formations which constitute two groups whithin the Komagfjord (the northernmost) tectonic window, it is purposed that the Precambrian rocks of the two windows be known as the Raipas suite.

	Stratigraphy and structure of the northern part of the Repparfjord - Komagfjord window, Finnmark, Northern Norway.

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU; No.377;1-45 pages

Abstract:

In the northern district of the Repparfjord-Komagfjord Window, supracrustal and intrusive rocks of Early Proterozoic age are unconformably overlain by a thin sequence of Vendian sediments. Both of these units are overthrust by allochthonous rocks of the lavas, tuffs and sediments of the Raipas Supergroup and intrusions of the Raudfjell Suite, regionally metamorphosed at greenschist facies during the polyphase Svecokarelian Orogeny, c. 1840 Ma. The c. 8 km thick supracrustal sequence is divided into four groups and eleven formations on a lithostratigraphic basis. The lithological characteristics of these units are described and compared with rocks of similiar age elsewhere in N. Norway. The stratigraphy and sedimentology of the thin (<200 m thick), autochtonous, Vendian cover sequence is also described. The caledonian Orogeny resulted in complex deformation of the autochtonous cover as well as considerable reactiviation of the underlying basement.
