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.
The report combines colour photographs with existing notes on some fragmented ophiolite sequences in Norway. The notes are from the 1981 Uppsala Caledonian Symposium excursion guide to Trøndelag, and from theses on Lyngen by Munday (1970) and Minsaas (1981).
