Summary
This report describes the mineral soil geochemistry results from two areas: 1) the entire Møre and
Romsdal county (n= 430), and 2) the Ålesund municipality (Møre and Romsdal county; n= 284). The
former is a continuation of previous surveys carried out in the Finnmark, Troms, Nordland, and
Trøndelag counties. During the main field work in 2019 and 2020, and complementary field work in
2021, 714 locations were sampled. The Møre and Romsdal county was systematically mapped (i.e.,
regional survey), whereas targeted urban geochemical mapping was done in the Ålesund municipalitiy.
For the regional survey, samples were collected based on a loose 6x6 km grid. Conversely, for the urban
soil sampling surveys 5 to 30 samples were collected per km2
. For both surveys, the <2 mm grain size
fraction was analyzed by IC-PMS 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, we report magnetic susceptibility measurements carried out
on the regional geochemical mapping survey
