Abstract

Geochemical map represents the concentration pattern for different elements in the surface media, for example, rocks and soils. Stream sediments are considered to be complementary to soils. The sediments are a composite sample of weathered material upstream from the sampling site. Sampling density varies from 1 sample per 1km<sup>2</sup> (stream sediment in Japan) to 1 per 320km<sup>2</sup> (till in Finland). A wider spaced sampling has been accepted in some cases. Geochemical map is expected to provide useful information on mineral exploration, environmental pollution as well as agricultural applications.
