Organic soil geochemistry in Nord-Trøndelag and Fosen
During field work in the summer and fall of 2013, organic soil samples were collected in a grid of 6 x 6 km 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 53 elements and Pb isotopes. The elements Be, In, Pd, Pt, Re and Te are kept out of the map collection due to very poor analytical data quality. 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.
