30. Spatial distribution of soil geochemistry in geoforensics

Soil geochemistry may be applied in the science of geoforensics in two ways: to establish the provenance of samples and to inform the question of sample variability. Tellus data can assist in answering on a broad scale the provenance question, ‘where may this sample have come from?’ Although the Tellus data are too widely spaced for precisely locating the source of a sample, the spatial variation …
