Environmental Monitoring And Peat Assessment Using Multivariate Analysis Of Regional-Scale Geochemical Data, Jennifer M. Mckinley, Eric Grunsky, Ute Mueller

Research outputs 2014 to 2021

A compositional multivariate approach was used to analyse regional-scale soil geochemical data obtained as part of the Tellus Project generated by the Geological Survey of Northern Ireland. The multi-element total concentration data presented comprise X-ray fluorescence (XRF) analyses of 6862 rural soil samples collected at 20-cm depth on a non-aligned grid at one site per 2km2" role="presentation">2km2. Censored data were imputed using published detection limits. Each soil sample site was assigned to the regional geology map, resulting in spatial data for one categorical variable and 35 continuous variables comprised of individual and amalgamated elements. This paper examines the extent …
