Dating tashkent geologist
The hydrogeological conditions, as well as the development of natural and techno natural hazards, are assessed at the next stage.
In this paper, the method and technique of compiling the map of subsurface zoning according to the geological conditions is discussed for two cities with difference geological conditions: Moscow (Russia) and Tashkent (Uzbekistan).
Vertical zoning of cities subsurface is controlled by three basic levels: up to a depth of 10 m, foundations of the most of the buildings are situated; up to a depth of 20 m, the highway tunnels are located, collectors of deep subsurface communication lines, and foundations of large multi-purpose complexes; up to a depth of 40 m, deep highway tunnels are located, and foundations of individual unique buildings.
In Moscow, the mid- and upper Jurassic clay layer and the Carboniferous carbonate-terrigenous complex are the most continuously stretching stratigraphic and lithological rock strata of permanent thickness.
A copper mine in a porphyry copper-gold-molybdenum deposit, started in 1958.
The mine works several ore bodies with different mineralization, among them Dalnee (Cu-Au-Ag), Kal'makyr (Cu-Mo-Au-Ag) and NW Balykty (Cu). This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys.
By combining multiple geochronological (and biostratigraphic) indicators the precision of the recovered age can be improved.
