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.
Geologiske data fra dalføret ved Gaupne i Sogn og Fjordane samt fra deler av Målselvdalføret i Troms er bearbeidet og visualisert i 3D ved hjelp av ArcGis modulet 3D Analyst og ArcScene. De bearbeidede data inkluderer kvartærgeologiske kart, seismiske data, georadardata samt bordata. Som grunnlag for 3Dmodellene er terrengmodeller som er basert på digitale, økonomiske kartdata. Georefererte innskaddede flyfotos er drapert på en av modellene.
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.
