En mineralogisk undersøkelse av utvalgte talkforekomster i Sogn og Fjordane, Oppland, Trøndelag, Nordland og Troms fylker.
Rapporten omfatter en kvantitativ og kvalitativ undersøkelse av en del talk- forekomster i de ovenfornevnte fylker. Kvantitativ bestemmelse er foretatt ved hjelp av røntgendiffraktometri (XRD) og modalanalyse. I tillegg er det utført mikrosondeanalyser og kjemiske analyser på en del prøver.

The KONTIKI final report summarises the results from the three-year KONTIKI project (CONTInental Crust and Heat Generation In 3D) established by NGU and StatoilHydro to improve the understanding of heat flow along the Norwegian continental margin. A compilation of c. 4000 new and old geochemical data is used to produce the first map of radiogenic heat production in bedrock, covering large tracts of Norway. In general granitic rocks have higher heat production than intermediate and mafic rocks.
The project has documented the existence of several previously unknown platinum group element (PGE) mineralizations in Norwegian ophiolites, of a type previously not well-documented anywhere, i.e. stratiform platinum- palladium-gold mineralization in ultramafic cumulates in ophiolites. PGE- bearing podiform chromitite and high level Ni-Cu sulphide mineralizations have also been studied.

Geodynamic modelling of the present crustal uplift indicates that the uplift of western Norway and northern Norway is partly due to other mechanisms that the glacioisostatic rebound. We have also deduced a new model based on the 'seismic pumping' mechanism to explain the observed correlation between land uplift and groundwater yield in Norway.
The Geological Survey of Norway and the Norwegian Petroleum Directorate established the TWIN Project (Tropical Weathering In Norway) in 2009 to improve the understanding of deep weathering on mainland Norway as well as offshore. All known reports of deep weathering in Norway have been reviewed and registered in a GIS database.
