Mineral soil geochemistry in Hedmark

This report present results from mineral soil geochemistry from a survey of former Hedmark county, now part of Innlandet county. It is a continuation of corresponding surveys undertaken in the counties Finnmark, Troms, Nordland, and Trøndelag. During the main field work in 2019 and 2020, and complementary field work in 2021, 787 locations where visited. The mineral soil samples were collected based on a loose 6x6 km grid. The <2 mm dried grain size fraction of these samples were analysed by ICPMS for 53 elements following an Aqua Regia digestion. Results are documented with respect to quality of data in tables with descriptive statistics, random plots, X-charts, and correlation plots, in addition to EDA geochemical maps of single elements. For the first time magnetic susceptibility is measured and made available for the samples collected by the national geochemical mapping program of mineral soil
