FORMATION SPECIFICS OF SOIL-GEOCAMICAL FIELDS IN THE SOIL SPACE OF THE AMUR R. BASIN: STRUCTURE AND MAPPING

Abstract

The distribution of elements of the geochemical background wasinvestigated in the Amur river basin. Background characteristics ofsoil-geochemicalspace were describedandsummarized. Conditions ofdispersionand steadiness ofelementsin the soilspace andmechanismsof geochemical fieldsformation in soil were revealed. Techniques of geo-statistics and numerical evaluationof geochemicalstructures were applied as an essential elementof geographical studiesfor creatingsoilgeochemical maps. Geochemicalsoilstructures were mapped for the Russian part of the Amur basin (1:2 500 000scale), usingGIS technologies and ArcGis10(ArcMap) software.
