Print this pageThe Recent Geodynamics and Effectiveness of Geochemical Exploration for Minerals
Polivtsev, Anatoliy V.,
Successes of contemporary soil science motivate us make new
requirements to the geochemical surveys. The evolutional rows of soils (A. Rozov, Ph. Duchaufour etc.), the soilgeomorphologic cycles and soil-biogeochemical
provinces (V. Kovda, M. Glazovskaya)
have been determined. Comparison of their site with the neotectonic
regimes of geostructures deposes the sensible
influence of the relief dynamics on composition and properties of recent soil
covering. This fact should be thought over and employed for correction of lithogeochemical exploration for minerals. So, we can
notice some tectonogeochemical effects.
1. Non-zonal soils
with geochemical specific occur on mobile areas regardless of theirperspectives for oil and gas (ores).
2. The
distribution of soil taxonomic units is controlled by combination of geostructuresin different range with tectonic activity.
3. The margins of
tectonic blocks (faults) displayed in changes of soil covering. Theactive faults revealed in linear combinations of
non-zonal soils.
4. The structure
regimes of continuous drop or rising cause simplifying of soil covering(convergence). The oscillatory (inverse) regimes
make the soil covering more complicated (divergence). Accordingly, the quantity
and composition of soil horizons have been change.
5. The aim of
geochemist-explorationist is to substantiate
correctly the representativehorizon for exploration
in various geodynamic conditions. The reasons of non-linear background and
barrier anomalies should be considered. So, success of exploration depends on
our ability to descry and employ masking or amplifying effects of geodynamics
on the dispersion halos.
