A turbidimetric method for the determination of small amounts of sulphur in limestone and dolomite.
(NGU (270), Journal article, 1971)It has been observed thaat on applying the combustion method to the determination of small amounts of sulphur in limestone and dolomite the bulk of sulphur may remain in the sample when no oxygen stream is used, and that ... -
Building stone of central and southern Ethiopia: deposits and resource potential
(NGU Bulletin (436), Journal article, 2000)The bedrock geology of Ethiopia exhibits a variety of rock types that can potentially be developed for building stone production. The ETHIONOR project has so far included investigation of such resources in the southern and ... -

III. Kalksten fra Nordland
(NGU (69), Journal article, 1914)Some analyses of limestones from Northern Norway are given. They show that the percentage of carbonate of Magnesium (MgCO3) is small in several of these lime- stones. They may therefore be used in the industries of carbide ... -
Industrial mineral quality of limestone; the effect of contact metemorphism on textural properties, brightness and geochemistry
(NGU Bulletin (436), Journal article, 2000)When carbonate are altered by contact metamorphism the industrial mineral quality of the rock can be affected. Based on two contrasting limnestone units from Oslo Rift, Norway, a study has been made of the impact that ... -
Industrial minerals - towards a future growth
(NGU Bulletin (436), Journal article, 2000)The Norwegian mineral industry has shown pronounced growth in recent years, and production and export of industrial minerals (sensu stricto), aggregates and dimension stone have all increased, whilst the production and ... -
