Mineral soil geochemistry in Nord-Trøndelag and Fosen
During field work in the summer and fall of 2013, mineral soil samples were collected in a grid of 6x6km in Nord-Trøndelag and Sør-Trøndelag’s municipalities of Trondheim and Malvik as well as on the Fosen peninsula. Together with samples for quality control, the <2mm fraction of samples from 752 locations were digested by aqua regia and analyzed for 57 elements. Results are documented with respect to quality of data and in tables of descriptive statistics, as well as plots of the cumulative probability function and by single element maps on a backdrop of bedrock geology. A selection of anomalies are briefly described, both areas of no known mineralizations, as well as anomalies of new elements in established ore-districts are covered.
