Mineraliseringene finnes nederst i østskråningen av Hoallumaras, rett vest for et myrdrag som går sørover fra Coav'jebåttusjav'ri. Letteste adkomst er langs gammelveien nordover fra Cabardasjåkka og deretter langs traktorvei vestover mot Maddjetjåkka. Gangavstand fra enden av traktorveien er ca. 5 km. Mineraliseringer av Bidjovagge-type opptrer i årer, langs stikk og disseminert i albittfels og i mindre grad i svartfels/svartskifer. Kobberkis og svovelkis er dominerende sulfider. Gull-innholdet er lavt (< 50 ppb Au). Albittfelsen og svartskiferen er 20-30 m mektig og grenser i vest til tuffittiske meatvulkanitter og i øst til metadiabas som dels er albitt-karbonat omvandlet.

	Interpretation of the Proterozoic Kautokeino Greenstone Belt, Finnmark, Norway from combined geophysical and geological data.

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU Bulletin; No.425;43-62 pages

Abstract:

Processed images of aeromagnetic, gravimetric and topographical data and geological maps combined with EM helicopter measurements, petrophysical data and digitised geological field observations have been used in a geological interpretation and structural analysis of the Kautokeino Greenstone Belt, KGB. The data were analysed with an image-processing system (geophysical data) and a geographic information system (geological data and interpretations). The bulk of the mafic volcanic rocks in the Kautokeino Greenstone Belt is situated within a NNW-SSE-trending, 35 km wide and up to 5-6 km deep trough which is thought to represent and Early Proterozoic rift deformed by strike-slip faulting along the Bothnian-Kvænangen Fault Complex,BKFC. The margins of the Alta-Kautokeino Rift, AKR, can be outlined from the geophysical data. The Ciegnaljåkka-Boaganjavri Lineament and the Soadnjujavri-Bejasjavri Fault are the main bordering fault zones and arc continuous along the entire greenstone belt. The supracrustals between these two zones are continuous to great depth (5-6 km) and the contracts along these bordering zones are steeply dipping. Gravity interpretations show that the outer amphibolite-facies rocks are just as deep as the central greenschist-facies unit. Results of the present study suggest that the amphibolite-facies volcano-sedimentary rocks situated along the flanks of the KGB should also be included in the rift.

	Blokkleting og geologisk rekognosering Grønnskiferområdet langs Stuoravassdraget mellom Hyolithussonen og Kautokeinoelven.

;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.254 A;11 pages

	Abstract:
	Blokkletingen og den geologiske rekognoseringen ble utført som ledd i de regionale malmundersøkelser i Finnmark. Det undersøkte området utgjør 850 - 900 km2. I tillegg til de regionale undersøkelser ble det utført detaljert blokkleting og geologisk kartlegging i et begrenset område på Gæssemaras. For undersøkelsene på Gæssemaras henvises til GM Rapport nr. 254 B.
