GIS Central Europe

BRGM R&D 'GEMS' Project

Toward a Metallogenic and Environmental GIS of Central and South-Eastern Europe

 

KEY WORDS: Central & South-Eastern Europe, GIS, Metallogeny, Ore deposits, Metal potential and fertility maps, Geodynamics, Environment, Risk maps.

GIS Central Europe was designed and initiated by BRGM in 2000 to be a homogeneous geographic information system for Central and South-Eastern Europe based on original syntheses and compilations. It covers an area of 1.7 million km² and extends for some 1750 km from the West Carpathian Mountains in the west to the Gulf of Antalya (southwestern Turkey) in the east (Cassard, 1999a - Fig. 1). Some 15 countries are concerned by this synthesis which covers the the Carpathian – Balkan Arc, the Dinarides – Hellenides Belt, the Rhodopean Massif and Western Anatolia.

GIS Central Europe has been conceived as a tool aimed primarily at the mining and academic sectors. For the former it will be an invaluable aid to mineral exploration and mine development, especially as it takes into consideration the environmental problems induced by the extractive industry and its downstream activities. For the latter it will aid in developing new metallogenic models, and should contribute to resolving certain R&D problems such as the relationship(s) between the mineralized belts and collision zones, subduction zones, thermal anomalies, etc., or the structural controls of the mineralization, or yet again the spatial and temporal distribution of the paleohydrothermal systems.

GIS boundaries

Area covered by GIS Central Europe between lat. 32° to 52° N and long. 12° to 31° E.

GIS Central Europe will contain the following thematic layers:

Layer

Description

GEOGRAPHIC

A DCW® geographic base (see Cassard, 1999c)

DEM

Two digital elevation models: one oceanic (2 minute arc), and one continental (30 second arc) elevation dataset with a structural analysis of the detailed topography

IMAGERY

SPOT 4 VEGETATION® satellite images at 1x1 km

GEOLOGIC MAP COVERAGE

Present state of geological coverage: location of and information on the existing maps

GEOLOGIC SYNTHESIS

Synthetic geological map of Central and South-Eastern Europe at 1:1,500,000 scale (see Cassard, 1999b and Nicol, 2000)

SIMPLIFIED GEOLOGICAL MAP

Simplified geological map of Central and South-Eastern Europe at 1:1,500,000 scale with characterization of morpho-structural domains and main tectonic elements (see Tomek et al., 1996)

VOLCANIC

Data on Holocene volcanism

GEOTHERMAL RESOURCES

Based on inventories at present being compiled for the EU

GEOCHEMISTRY

Composition and age of magmatic and volcanic rocks – isotope data

ORE DEPOSITS

Linked to a database under Access®, using a new metallogenic lexicon (see http://gisandes.brgm.fr/ore_depo.htm) and including mineralogical (ore, gangue and hydrothermal alteration), fluid-inclusion and isotopic data of the main ore deposits (see http//:gisandes.brgm.fr/mineralo.htm)

GEOCHRONOLOGY

Synthesis of existing data, methods used, critical analysis, reliability, references, etc. (collaboration with Utrecht University)

MINING DISTRICTS AND PROVINCES

Delimitation, magmatic and structural controls, potential and information on mining companies (see Jankovic, 1997)

HEAT FLOW

(see Cermak, 1993)

GRAVIMETRIC

Bouguer anomaly calculation; isostatic correction and corresponding residual anomalies; vertical gradient calculation and structural analysis

SEISMIC

Distribution of earthquakes in order to better understand and constrain the crustal structures

MOHO

Depth contour map (e.g. Nemcok et al., 1998);

3D TOMOGRAPHY

3D model of the lithospheric structure (collaboration with Utrecht University – see de Boorder et al., 1998);

SOCIAL AND ENVIRONMENTAL FACTORS
  • A qualitative and quantitative pollution hazard database of mine-waste/tailings
  • Maps of potential pollutant transfer pathways, including surface and ground water and sufficient climatic data to assess atmospheric transfer
  • Socio-economic data maps for assessing potential pollution risks
