Østre Aris gang ligger på sørsida av elva, 1.5 km vest for sørenden av Arisvatnet. En grunnstoll med retning N142Ø går inn 3 m over elva. En vannfyllt skråsjakt er anlagt 8 m over dette stollnivået. Sulfidmineraliseringene består av massiv magnetkis med mindre mengder kobberkis i en grovkornet kvarts+karbonat gang. Den mineraliserte gangen er ikke blottet i skjaktåpningen, men en 70 cm bred, umineralisert kvartsgang i grønnstein er blottet 15 m sørøst for skråsjakta. Denne er parallell skifrigheten i grønnsteinen.

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.

Abstract:
Etter oppdrag fra A/S National Industri har Norges geologiske undersøkelse i årene 1964 - 1968 gjennomført undersøkelser av malmforekomstene i Repparfjord. Undersøkelsesprogrammet har omfattet geofysikk og geokjemisk prospektering, geologisk kartlegging og diamantboringer. Den geofysisk og geokjemiske pros- pekteringen samt diamantboringsprogrammet ble fullført i 1967. I sesongen 1968 har man undersøkt nærmere de geofysiske og geokjemiske anomalier som er frem- kommet utenfor selve malmfeltet samt fullført den geologiske kartleggingen av området. Et fremtidig malmletingsprogram vil naturlig falle i to deler. a) Å under- søke Ulverygg-malmens eventuelle fortsettelse videre øst, og vestover samt dens forløp mot dypet i Hovedfeltet. b) Å undersøke de påviste impregnasjonsområdene mellom Bratthammer og Stein- fjell samt å drive et videre arbeid vestover i kvartsittområdet. Likeledes kan det være aktuelt å se nærmere på forekomster i Porsafeltet.

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.
