| Abstract |
| Oxide- and apatite-rich modally layered rocks in the lower part of the Bjerkreim-Sokndal Layered Intrusion in the Rogaland Anorthosite Province. The area is conventionally denoted MCUIB-e and defines a sequence of apatite-, ilmenite- and magnetite-bearing gabbronorite which may be followed from the farm at Åsen to Bjerkreim. The area is densely covered and the sequence only rarely exposed. The poor exposure makes it difficult to confidently assess the persistency and aerial extent of the MCU1Be target area. However, the overall similarities observed in profiles across the zone in terms of layering and mafic index do suggest that a prominent apatite-, ilmenite- and magnetite-rich zone exists. The zone varies in thickness from 15-20 to 60 m and is likely to be laterally continuous for at least 3 km wedging out gradually to the north and south. |
| Description |
| MCU1B distinguishes itself from the mega cyclic units 3 and 4 in one important way: It does not contain any magnetite-bearing b- or d-zones, which means that the first appearance of apatite and magnetite is simultaneously at the base of zone MCU1Be. The MCU1Be is a relatively narrow zone of apatite, magnetite and ilmenite-rich cumulates extending south and southwest from the hinge zone of the intrusion near the village of Bjerkreim. The zone is 40-90 m wide and may be followed along strike for approximately 4 km. The stratigraphy has been offset by a number of minor faults. At Åsen, south of lake Berse, the zone is exposed in the slopes of a deep erosional valley, and to a large part covered by glaciofluvial sediments. The sample profile (Profile 1/ Location 1) consist of 9 samples from a prominent melanocratic apatite-, ilmenite- and magnetite-rich gabbronorite sequence in intensely layered cumulates. In major parts of this sequence mafic layers make up 60-70% of all exposures. The profile includes 9 samples which covers a stratigraphic interval of 100 m. The lowermost sample is located within MCU1A-c zone (no apatite) and the uppermost sample well within the MCU3-a zone (no apatite). 6 samples from the central part of the profile represents a 60m thick zone of significant economic interest. The zone is thinning out towards both south and north. Norm calculations from XRF whole rock analyses gives a total of 15.5% ilmenite, 11% magnetite and 9% apatite. The mineral composition of ilmenite and magnetite has been analysed by electron microprobe giving in average 2 % MgO in ilmenite and 0.95% V2O3 in magnetite. |

| The deposit located at Åsen corresponds to profile 1 and location 1 in the sample list. It is part of the same zone (MCU1B-e) as the deposit described as Bjerkreim SW (profile 2/ location 2). At Åsen, south of lake Berse, the zone is exposed in the slopes of a deep erosional valley, and to a large part covered by glaciofluvial sediments and talus (see picture below). The sample profile consists of 9 samples from a prominent melanocratic apatite-, ilmenite- and magnetite-rich gabbronorite sequence in intensely layered cumulates. In major parts of this sequence mafic layers make up 60-70% of all exposures. The profile covers a stratigraphic interval of 100 m. The lowermost sample is located within MCUIA-c zone (no apatite). The sample at 10 m represents a gradual increase in the amount of apatite accompanied with a similar increase in ilmenite amounts and MgO in ilmenite. The same gradual increase is seen for the amount of magnetite although a few meters delayed. At the level of 43 m a local abrupt fall is seen in the amounts of ilmenite and magnetite accompanied by a simultaneous fall in the MgO of ilmenite and the V2O3 of the magnetite. The two samples at this level represent a mafic and felsic layer respectively, the felsic layer representing the low amounts. The amounts of apatite do not fall synchronously, but remains fairly constant in the 6 samples until reaching the uppermost sample, which is situated well within the MCUIII-a zone (no apatite). 6 samples from the central part of the profile thus represent a 60m thick zone of significant economic interest. The zone is thinning out towards the south. Norm calculations from XRF whole rock analyses gives an average of 15.6% ilmenite, 10.9% magnetite and 9.2% apatite. The mineral composition of ilmenite and magnetite has been analysed by electron microprobe giving in average 1.97 % MgO in ilmenite and 0.94% V2O3 in magnetite. |

| 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. |

| 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 |

| 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. |

| 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. |
