Rundingens og petrografiens innflytelse på sprøhet og flisighet av naturlige grusforekomster, belyst ved eksempler fra noen norske dalfører.
(NGU (363), Journal article, 1981)Gravel deposits in five Norwegian valleys have been investigated with regard to petrographic composition, roundness, transport directions, brittleness and flakiness. These prarameters are all found to be very complex. ... -
Rundingsanalyser på grus- og steinpartikler - et nyttig hjelpemiddel ved undersøkelser av løsmassenes genese.
(NGU; Skrifter (379; 39), Journal article, 1983)A combined method for determination of clast roundness based on a visual estimation method and the newly defined parameter crushing, provides good and quite detailed information on the total roundness of a collection of ... -
Rutile associated with eclogites in western Norway and scapolitised gabbros in southern Norway
(NGU Bulletin (427), Journal article, 1995) -
Rutile in eclogites as a mineral resource in the Sunnfjord Region, Western Norway.
(NGU Bulletin (436), Journal article, 2000)The world's resources of the primary titanium raw materials ilmenite and rutile are very large. However, there is a lack of high-grade, high-quality ilmenite deposits as well as good rutile deposits. Particular focus has ... -
Rørbrønner ved Rena og Elverum. Meddelelse fra vannboringsarkivet nr. 8.
(NGU (205), Journal article, 1959)Topography and climatis conditions are favourable for the utilization of surface water in Norway, such that the ground water does not play the same role for the water supply as in most countries During the last years, ... -
Rørbrønner. Meddelelse fra Vannboringsarkivet nr. 12.
(NGU (215), Journal article, 1962)During the last years several screened wells are build in glacifluvial deposits in different valleys in Norway. The yield of the wells are 1000-7000 1\/min. The quality of the water is very satisfactory. -
Rørbrønnfiltere. Meddelelser fra Vannboringsarkivet nr. 13.

Røros. Beskrivelse til kvartærgeologisk landgeneralkart
(NGU (198), Journal article, 1956)The present map, dealing with the quarternary deposits of Røros, is partly based on existing maps of a larger scale, certain of which have been published. Areas not geologically mapped beforehand were surveyed in the susal ... -
Saline groundwater extraction from the fjord delta aquifer, Sunndalsøra, Møre og Romsdal, Norway
(NGU Bulletin (422), Journal article, 1992)The fjord delta at Sunndalsøra has been investigated by geophysical measurements, drilling and pumping in order to examine the possibilities of saline groundwater for use in fish farming. A geological model of the delta's ... -
Salta. Beskrivelse til det geologiske generalkart.
(NGU (134), Journal article, 1929)Of eruptive rocks granite is predominating. More subordinate gabbro rock and at some places perdotite occur. The stratified rocks are schists, limestone and gneiss with a few sections of slaty quartz rock. In the coast ... -
