Geochemical testing covered the entire territory of Uzbekistan, but with varying degrees of detail. Most, 85-88% of the republic's area is covered with Mesozoic and Cenozoic sediments, with which exogenous deposits are associated. Pre-Mesozoic formations - the environment of localization of endogenous deposits, confined to the mountain systems of the Median and South Tien Shan. Mountain heights with outcrops of Pre-Mesozoic rocks occupy about 12-15% in area, the rest is in semi-closed and closed territories. Primary halos are recorded on the surface and at depth, secondary ones on the surface, as well as near it: below the raft - in water, above - in the surface atmosphere. Improving forecasting efficiency in regional geochemical works, interpretation and assessment of different-rank ore-generating geochemical anomalies in complex landscape-geological conditions.
