Conceptual formational model of imposed sorption-salt and nanochemical halos

This paper considers processes of formation, transportation and deposition of the sorption-and-salt and nano-mechanical forms of the ore substances in soils and near-ground air. Generation of the soluble forms is mainly determined by chemical weathering of ore bodies, whereas nanoparticles are principally formed in processes of their mechanical disintegration. Further evolution of these forms manifests as their upward movement to the ground surface as a result of the convective and quasi-convective mass transport. Immobilization of the soluble and nano-mechanical forms in the near-surface environment is caused by transpiration and their sorption by various soil components. It is the Method of Analysis of Superfine Fraction (MASF) developed in FGUP VSEGEI which is specifically based on studying the forms of ore substances adsorbed on the surfaces of micro- and nanoparticles of soils. A portion of the metallic nanoparticles comes in the near-ground air and forms nano-chemical anomalies which are the systems comprised of gases and aerosols saturated with solid nanoparticles. The instrumental determination of these nanoparticles is the basis of the Geocosmic Remote Sensing of Nano-Anomalies technique (GRSNA).
Key words: sorption-and-salt forms, nanoparticle, convective mass transport, superimposed sorption-and-salt dispersal pattern, nano-chemical anomaly.
