A beryllium-magnetite correlation in the Hørtekollen-Grubeås area, Buskerud, Norway, and its use for beryllium prospection.
(NGU (223), Journal article, 1963)A helvite-magnetite mineralization at Hørtekollen was studied for its beryllium and magnetite contents. Statistically, a close correlation between the magnetite and the beryllium contents was found to occur. Therefore a ... -
Bjerkreim-Sokndal intrusjonen, Rogaland - Muligheter for videreforedling av vanadiumholdig magnetitt og ilmenitt i kombinasjon med bruk av CO2.
(NGU-Rapport (2004.030), Report, 2004)Forkortet:Bjerkreim-Sokndal intrusjonen i Rogaland Anortosittprovins (Egersundfeltet) eranriket på ilmenitt, vanadiumholdig magnetitt og apatitt på visse nivåer i denmagmatiske seksvensen. Omtrent 50 km2 av intrusjonen ... -
Chemical and petrographic characterization of ilmenite and magnetite in oxide-rich cumulates of the Sokndale Region, Rogaland, Norway
(NGU Bulletin (436), Journal article, 2000)Igneous ilmenite and magnetite in some oxide-rich cumulates of the Sokndal region show chemical features and microtextures that reflect the progress of magmatic evolution and subsolidus re-equilibration. These features ... -
Chemical characterisation of ilmenite, magnetite and apatite in the Bjerkreim-Sokndal Layered Intrusion, Rogaland, South Norway
(NGU-Rapport (2002.042), Report, 2002)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 ... -
Den manganholdige siderittmalm i Rubben, Troms. Undersøkelser sommeren 1959.
(NGU (211), Journal article, 1960)An occurence of mangan-bearing siderite ore i Rubben, Troms, Northern Norway. An occurence of manganese-bearing siderite ore i Rubben, Torms, Northern Norway, was investigated during some days in the summer of 1959, and ... -
Eisen-TitanlagerstÌtten bei Raudsand, Westnorwegen.
(NGU (234), Journal article, 1965)A number of magnetite-ilmenite deposits near Raudsand in western Norway are described. The orebodies lie in lenses and plates of amphibolite. These amphibolites are conformable within the surrounding late precambrian or ... -
Forekomster med ilmenitt, vanadiumholdig magnetitt og apatitt i norittiske bergarter i Egersundfeltet, Rogaland
(NGU-Rapport (2001.014), Report, 2001)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 ... -
Resources of apatite, ilmenite and magnetite in the Bjerkreim Sokndal Layered Intrusion, Rogaland, South Norway
(NGU-Rapport (2001.092), Report, 2001)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 ... -
Rock-magnetic properties, oxide mineralogy, and mineral chemistry in relation to aeromagnetic interpretation and the search for ilmenite reserves
(NGU-Rapport (96.060), Report, 1996)The understanding of the rock-magnetic properties of the various oxide ores and country rocks in the vicinity of the Tellnes Deposit is a first step toward a successful interpretation of the aeromagnetic maps (NGU Report ... -
Serpentinitt ved Mødal på Kvamskogen
(NGU-Rapport (95.043), Report, 1995)Etter initiativ fra grunneier Bård Sandven ble en serpentinittforekomst i Mødalen på Kvamskogen befart. I området er det flere forekomster, men kun den klart største ble nærmere undersøkt. Den har et dagareal på omkring ...
