Mineral soil geochemistry in southern Trøndelag

Abstract

This survey constitutes a continuation of corresponding surveys undertaken in Finnmark, Troms and Nordland Counties, as well as in North Trøndelag and on Fosen. During the main field work in 2018, and the complementary field work in 2019, mineral soil samples were collected in a grid of 6x6 km in the remaining part of south Trøndelag. In total 462 locations where sampled. The <2 mm dried grain size fraction of these samples were analysed by ICPMS for 53 elements following 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.The data are briefly compared with previously survey data.
