| Abstract |
| Oxide- and apatite-rich modally layered gabbronorite in the Bjerkreim-Sokndal Layered Intrusion in the Rogaland Anorthosite Province. The stratigraphic sequence, to wich the Teksevatnet-Timrevik deposit belong, is conventionally denoted MCU3-e and may be followed along strike from Rappstad in the southern extension around the hinge of the Bjerkreim lobe to Ualand in the northeastern extension - a total distance of approximately 25 km - but is absent for about 8 km in the central part of the intrusion, due to extensive dyke emplacement (the Lomland Jotunitic Dyke). The thickness of the zone is variable, both stratigraphically and in exposure, decreasing from up to 300 m in the central most part to around 50 m on the flanks. Although the presence of a persistent melanocratic apatite- and oxide-enriched sequence has not been fully documented (partly due to lakes and sedimentary cover) in the MCU3e, melanocratic sequences are at least very frequent. |
| Description |
| The northern flank is overall more melanocratic than the southern flank (see deposit Helleland), and extensive sampling has been performed at Terland N. and Teksevatnet-Timrevik. At Terland N. the MCU3e zone has a total stratigraphic thickness of 300 m. Here, at Teksevatnet-Timrevik, 2.5 km further southeast, the thickness of MCU3e has been reduced to around 80 m. Due to extensive cover and a major fault zone, it is not possible to trace the zone continuously between these two profiles. Further East from the Teksevatnet-Timrevik locality our investigations were somewhat hampered by poor exposure, but a melanocratic gabbronorite was encountered, but not sampled in the top of MCU3e at Bjørnemoen. An isolated sample at Vasshus, 9-10 km south-east of the Teksevatnet-Timrevik profile further indicates that the zone is continuous. The profile at Teksevatnet-Timrevik is taken along fresh outcrop along the lake shore. The lowermost sample from this profile is taken in the underlying MCU3d zone (no apatite). In contrast to Terland N., the base of MCU3e at Teksevatnet-Timrevik is characterized by relatively homogenous gabbronorites. Above this interval the sequence is characterised by intensive layering, where 2-30 cm thick melanocratic layers dominate over leucocratic layers. A total of 16 samples represents an 80m thick sequence. The detailed sampling in this profile includes pairs of felsic and mafic parts of layers at each stratigraphic level. It has turned out that mafic layers are systematically enriched in apatite (and magnetite and ilmenite) relative to felsic counterparts of the same layers. Norm calculations from XRF whole rock analyses gives a total of 10.5 % ilmenite, 6.5 % magnetite and 7.5 % apatite. The mineral composition of ilmenite and magnetite has been analysed by electron microprobe giving in average 1.5 % MgO in ilmenite and 0.95 % V2O3 in magnetite. |

| The deposit located at Teksevatnet-Tiimrevik is part of the same zone (MCU3-e) as the deposit descibed as Helleland and Terland N.. The profile at Teksevatnet West is situated along the lakeshore southeast of Slettebø. The distance to the profile at Terland North is 2.5 km and the thickness of the geological unit (MCU IIIe) hosting the deposit is reduced from 300m at Terland to less than 100m at Teksevatnet. Due to extensive cover and a major fault zone, it is not possible to trace the zone continuously between these two profiles, but inscepction and sampling at Øygrei confirms the presence of the deposit between Timrevik and Terland N.. Towards the east our investigations were somewhat hampered by poor exposure in the area between the two lakes of Teksevatnet and Bilstadvatnet. A melanocratic sequence of gabbronorite was encountered, but not sampled in the top of MCUIIIe at Bjørnemoen. An isolated sample at Vasshus, 9-10 km south-east of the Teksevatnet West profile further indicates that the zone is continuous, but further reduced in thickness. The profile at Teksevatnet West is taken along wave polished outcrops. The lowermost sample from this profile is taken in the underlying MCUIIId zone (no apatite). In contrast to Terland N., the base of MCUIIIe at Teksevatnet West is characterized by relatively homogenous gabbronorites. Above this interval the sequence is characterised by intensive layering, where 2-30 cm thick melanocratic layers dominate over leucocratic layers. A total of 16 samples represent an 80m thick sequence. The detailed sampling in this profile includes pairs of felsic and mafic parts of layers at each stratigraphic level. It has turned out that mafic layers are systematically enriched in apatite (and magnetite and ilmenite) relative to felsic counterparts of the same layers. Also the MgO in ilmenite and the V2O3 in magnetite mimics this pattern being relatively high in dark layers and respectively lower in felsic layers. Norm calculations from XRF whole rock analyses gives a total of 10.6 % ilmenite, 6.6 % magnetite and 7.6 % apatite. The mineral composition of ilmenite and magnetite has been analysed by electron microprobe giving in average 1.4 % MgO in ilmenite and 0.94 % V2O3 in magnetite. |

| 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. |

| 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 |

| 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. |
