(NGU (255), Journal article, 1968)The Porsanger Sandstone Formation forms an imbricated thrust mass lying between the Precambrian Basement Complex to the south-east and an allochthonous nappe of \"Caledonian\" metamorphic rocks to the north-west. The ... -
The potential use of ferromanganese-depositing bacteria as a treatment method for heavy-metal-contaminated water, a literature study
(NGU-Rapport (92.219), Report, 1992)Norway is particularly susceptible to potential pollution of its water resources by heavy metals due to: (i) the importance of its fishing and water-related interests, (ii) the large number of industries, including mining, ... -
The Precambiran schists and gneisses of Lakselv valley, northern Norway.
(NGU (205), Journal article, 1959)The principal rocks of the Lakselv valley area are well-foliated hornblende schist and mica-quartz schists and lesser amounts of quartzite and marble. The hornblende schist overlies most of the mica-quartz schists and in ... -

The prospectivity of the Barents Sea: Ice ages, erosion and tilting of traps
(NGU-Rapport (2003.102), Report, 2003)A three-phase conceptual glacial geological model for the Late Pliocene and entire Pleistocene period has been developed. The model explains variations in erosion in the Barents Sea in space and time and shows:\rThe first ... -
The Raudfjellet ophiolite fragment, Central Norwegian Caledonides: principal lithological and structural features.
(NGU Bulletin (445), Journal article, 2005)The Raudfjellet complex, Nord-Trøndelag, displays several of the features of a classical ophiolite pseudostratigraphy. At its base is a spectacular ultramafic mylonite. Elements represented include: (1) Ultramafic rocks, ... -
The relation between the basal gneiss and the overlying meta-sediments in the Surnadal district, (Caledonides of Southern Norway).
(NGU (184), Journal article, 1953)The boundary between the basal gneiss and the overlying micaschists and micaceous gneisses is marked by a thin zone of \"basal quartzite\", but the quartzite is generally not at the exact boundary between the two divisions. ... -
