Helicopter-borne magnetic and radiometric geophysical survey in Dividalen, Målselv municipality, Troms county

NGU conducted an airborne magnetic and radiometric survey in the Dividalen area in September 2013 and October 2014 as a part of the MINN project (Mineral resources in Northern Norway).This report described and documents the aquisition, processing and visualization of recorded datasets. The geophysic...
