Abstract
New high-resolution aeromagnetic and radiometric surveys in Finnmark and North Troms: linking anomaly patterns to bedrock geology and structure
Highlights
The Geological Survey of Norway (NGU) has conducted aeromagnetic surveys on the Norwegian mainland and continental shelf since 1959 (Olesen et al, 2010) and up to the present day the entire country has been covered by airborne magnetic data
In doing so we will highlight some of the principal magnetic anomalies, folded anomalies and anomaly offsets, as well as radiometric zoning patterns, and relate such features to the bedrock geology of this vast region
On the ternary map of radiometric data, the Sørvaranger–Kola Terrane (SKT) is shown with very pale green colours indicating high levels of K, U and a predominance of Th (Fig. 7)
