METHOD OF DETECTION OF GEOCHEMICAL ANOMALIES BASING ON ANALYSIS OF CHEMICAL COMPOSITION OF RIVER SEDIMENTS

摘要

FIELD: chemistry.;SUBSTANCE: geoinformational analysis of the studied territory is carried out. 2-3 samples of bottom sediments on small-inflow areas with a relatively sharp reduction of water exchange intensity are collected. The chemical composition of the collected samples is carried out and an average concentration of the substance is calculated. Regions with increased vales of the concentration are studied in more detail, carrying out more frequent sampling of the bottom sediments of rivers and other components of the environment. In the period with water runoff, close to mean long-term values, detailed specialised geological-chemical mapping of a prospective area is carried out.;EFFECT: detection of geochemical anomalies basing on the analysis of the chemical composition of the bottom sediments of rivers.;1 dwg
