Maps of mineral deposits occurrence

A set of maps of mineral deposits occurrence constitutes the supplement and the graphic representation of information contained in a publication ‘The balance of mineral deposits resources in Poland’.

Maps are prepared on a basis of spatial information collected on a regular basis in the System of management and protection of mineral resources in Poland - MIDAS. Main data sources for the MIDAS System - on mineral deposits boundaries, are geological documentations of deposits. When a deposit contour cannot be obtained from a documentation, data sources are documents being sent to the Registry of mining areas and closed underground carbon dioxide storage facilities. The maps were designed for mineral deposits covered by mining ownership (state ownership) – excluding groundwater allocated under minerals – and for the majority of remaining mineral deposits.

In parallel with ‘The balance…’, there are annually elaborated: four maps at scale 1:200,000, two maps at scale 1:500,000 and seven maps at scale 1:1,000,000. In addition, there was a map presenting all documented mineral deposits in Poland prepared (at scale 1:1,800,000). The maps are being prepared with a state of deposits documentation and development as of the end of the previous year.

The first (I) group contains maps prepared at scale 1:200,000 on which deposits boundaries are presented using contours and signature marks. There are also information on a state of deposits development presented. The map of hard coal deposits occurrence in the Upper Silesian Coal Basin also defines an affiliation of an individual mine to a particular economic entity. The second (II) and third (III) groups contain maps at scale 1:500,000 and 1:1,000,000 on which deposits location is presented using point signatures. These maps contain also information on a state of deposits development and on the volume of deposits resources.
