Geological atlas of St. Petersburg

Description

St.Petersburg: Comilfo, 2009. — 57 p.The Atlas includes eight sections reflecting the state of geological environment of the city. It contains information on the geological structure, hydrogeological structure, hydrogeological and engineering geological characteristic of the area, data on geological structure of the bottom of the Gulf of Finland, zones of recent geological processes. The section Integral assessment of geological risks devoted to current geological processes that affect negatively the urban environment takes a special position in the Atlas.The Geological Atlas of St. Petersburg can be used for accounting characteristics of the subsurface space in the process of its development, environmental and ecogeological risk mitigation during the elaboration and realization of urban development plans.Physiographic s review History of geological investigations in Saint Petersburg Geomorphology Maps: Geomorphologic map (scale 1: 350,000) Geological structure Pre-Quaternary deposits Quaternary deposits Surface deposits of the sea floor Tectonics, neotectonics Maps: Geological map of Pre-Quaternary deposits (scale 1:200,000) Geological map of Quaternary deposits of land (scale 1:200,000) Geological map of Quaternary deposits in the Neva Inlet and the eastern Gulf of Finland (scale 1:200,000) Lithologic map of the bottom surface in the Neva Inlet and eastern Gulf of Finland (scale 1:200 000)Geological map of the crystalline basement (scale1:350,000) Map of recent tectonic activation (scale 1:350,000) Hydrogeological structure and engineering-geological conditions Hydrogeological structure Engineering-geological conditions Maps: Hydrogeological map of Quaternary deposits (scale 1:200,000) Hydrogeological map of Pre-Quaternary deposits (scale 1:200,000) Engineering-geological map of the day surface (scale 1:200,000) Engineering-geological map of the day surface in the city centre (scale 1:50,000) Engineering-geological map of the 10-metre depth slice (scale 1:200,000) Engineering-geological map of the 10-metre depth slice in the city centre (scale 1:50,000) Mineral resources State of geological environment and exogenous geological processes Exogenous geological processes Underground gases Effect of ground water management on the state of geological environment: case study of the Vendian aquifer system Geological and hydrogeological construction constrains Maps: Map of exogenous geological processes (scale 1:200,000) Map of underground gas shows (scale 1:1,000,000) Map of biogas shows (scale 1:200,000) Maps of piezometric levels in the Vendian aquifer system, Diagrammatic section Zoning map in respect of construction constrains (scale 1:200,000) Integrated geological risks assessmentMaps: Geological risk maps (scale 1:600,000) Risk map in respect of construction constrains (scale 1:200,000) Map of integrated geological risks assessment (scale 1:200,000)
