Sammendrag

Bjerkreim-Åsen er den vestligste og minste av de tre sonene i Bjerkreim-Sokndal lagdelte intrusjon som inneholder størst konsentrasjon av mineralene ilmenitt, apatitt og magnetitt. Sonen strekker seg fra Bjerkreim og sørover ca 4 km til Åsen gård. Tykkelsen på sonen varierer fra 45-50 m, men kiler ut nord for Bjerkreim og sør for Åsen. Selve sonen er noe forstyrret av en serie mindre forkastninger og har relativt få blotninger på grunn av sterk vegetasjon og overliggende kvartære avsetninger (marin leire og morene). Sonen er prøvetatt ved Åsen (9 prøver i et profil over 100 m) og sørvest for Bjerkreim (5 prøver tatt i profil og 1 prøver isolert sør for Bjerkreim) nord for Bersevatn. Normative XRF whole rock-analyser for prøvene prøvene tatt ved Bjerkreim gir snittverdier på 14,5% ilmenitt med 1,5% MgO, 10% magnetitt med 0,9%V2O3 og 7% apatitt.

	An overview of titanium deposits in Norway

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU Bulletin; No.436;27-38 pages

Abstract:

Titanium deposits in Norway are of three major types: igneous, metasomatic and metamorphic. The igneous deposits are compared of ilmenite, magnetite and apatite in various proportions and occur in geological provinces of different ages. and some have a metamorphic overprint. The other majord Ti ore-types is the rutile-bearing eclogites in western Norway that formed during the Caledonian high-pressure metamorphism of predominantly Proterozoic basic igneous rocks. The third Ti ore-Type is the Proterozoic rutile-bearing, scapolitised and albitised rocks in the Bamble region of South Norway.

	Chemical characterisation of ilmenite, magnetite and apatite in the Bjerkreim-Sokndal Layered Intrusion, Rogaland, South Norway

;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.2002.042;25 pages

Abstract:

During 2001 cooperation was established between NGU and Norsk Hydro Agri in order to locate combined resources of apatite, ilmenite and vanadium magnetite in the Bjerkreim-Sokndal layered Intrusion in the Rogaland Anorthosite Province of aouth Norway. It had previously been recognized that a potential existed for finding coexisting apatite, low-Mg= ilmenite and vanadium-rich magnetite in the northern part (the Bjerkreim-lobe) of the layered intrusion. It had also become apparent that none of the minerals are present in amounts that can support exploitation of one mineral alone. Fieldwork was undertaken during July 2001 with the purpose of locating and constraining the most promising areas in terms of volume and grade of the three target minerals in the Bjerkreim-lobe. Three apatite-bearing and oxide-rich zones were singled out, sampled and preliminarily constrained. These zones are located with one area in mega-cyclic unit (MCU) IBe (Åsen-Bjerkreim), containing up to 41% of the three minerals, two areas in MCU IIIe (Helland and Terland respectively), with up to 34% of the three minerals, and in MCU IVe (Teksevatnet-Vasshus), with 32% ilmenite, magnetite and apatite. The fieldwork and subsequent whole-rock chemical analyses (XRF) were described and discussed by Schiellerup et al. (2001). In the apatite. and oxide-rich part of MCU IBe the MgO-content of ilmenite vary between 1.36 and 2.26% with an average of 1.8%. Stratigraphically dependant variation has not been resolved and the highest MgO contents in ilmenite tend to occur in the most mafic layers. In the two MCU III prospects at Helleland and Terland the MgO-content in ilmenite averages 2.2 and 2.5% respectively, whereas the Teksevatnet profile yield an average of 1.4% MgO in ilmenite. In the Teksevatnet profile the modal contrast between mafic and felsic layers is exceptional and the MgO-content of ilmenite is consi

	Resources of apatite, ilmenite and magnetite in the Bjerkreim Sokndal Layered Intrusion, Rogaland, South Norway

;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.2001.092;33 pages

Abstract:

The Rogaland Anorthosite Province in southwest Norway is well known for its many ilmenite deposits, of which Tellnes is at present the only one in product- ion In addition to ilmenite, the province carries a significant potential for apatite and vanadium-rich magnetite occurring in the layered series of the Bjerkreim-Sokndal Layered Intrusion. The current study was undertaken in order to locate exploitable resources of combined apatite, ilmenite and vanadian magnetite in the Bjerkreim-lobe of the Bjerkreim-Sokndal intrusion.

	Forekomster med ilmenitt, vanadiumholdig magnetitt og apatitt i norittiske bergarter i Egersundfeltet, Rogaland

;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.2001.014;29 pages

Abstract:

Ved tidligere undersøkelser er det påvist at norittiske bergarter i omrpåden Sokndal og Bjerkreim inneholder betydelige mengder av apatitt, ilmenitt og vanadiumholdig magnetitt, men at forekomstene er lavgehaltige. En rekke norittrelaterte forekomster inneholder i størrelsesorden 10% apatitt, 10% ilmenitt og 10% magnetitt. De minerallogiske kvaliteter synes å være gode. For eksempel forekommer ilmenitt med relativt lavt MgO-innhold (i størrelsesorden 1%) og magnetitt med høyt V-innhold (0.7-1.2% V2O2) sammen med C1-fattig apatitt i visse deler av området, noe som er positivt med tanke på mulighetene for framtidig gruvedrift. Samtidig er de samlede ressurser av kombinert apatitt ilmenitt og vanadiumrik magnetitt store. Og det burde være rimelig gode muligheter til å påvise nye forekomster med minst like gode kvaliteter som de som er påvist fram til nå.
