Maps of mineral raw materials deposits occurrence
The set of maps of raw materials deposits occurrence constitutes a supplement and a graphic representation of the information contained in a publication “The balance of mineral resources deposits in Poland”.
Maps are prepared on the basis of the spatial information collected on a regular basis in the System of management and protection of mineral resources in Poland MIDAS. The main data sources on raw materials deposits boundaries are geological documentations of deposits. When a deposit contour cannot be obtained from a documentation the data sources are documents being sent to the Registry of mining areas and closed underground carbon dioxide storage facilities. The maps were designed for the raw materials deposits covered by mining ownership (state ownership) – excluding groundwater allocated under minerals – and for the majority of deposits of the remaining raw materials.
In parallel with the publication “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. The maps are being prepared with the state of deposits documentation and development as of the end of the previous year.
On maps at 1:00,000 scale deposits boundaries are presented using contours and signature marks. There are also information on the 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. On maps at 1:500,000 and 1:1,000,000 scale deposits location is presented using point signatures. These maps contain also the information on the state of deposits development and on the volume of deposits resources.
