National Geofund and Geology (NGG)
National Geofund Geological data collected in the last 50 years More than 7000 reports covering all aspects of geological activities In charge of disclosure of unpublished information to another organizations under established rules.
National Geofund Two ways to find reports of interest In GeoArchive DB Using graphical interface for the areas in which geological works have been done
Geological Map of Bulgaria Scale 1: Published in flat coloured sheets covered all territory of Bulgaria Bulgarian-English edition Digital model available (MapInfo) The map is compiled on the base of the Geological map of Bulgaria scale 1: and available data of the National Geofund
Fragment of 1: map in real scale
Geological Map of Bulgaria Scale 1: Scale 1: Published Map Series 86 coloured flat sheets, covered all the country Bulgarian or English edition Available in digital form (MapInfo)
Digital Map, example
Geological Map of Bulgaria Scale 1: Scale 1: Unpublished map series Standard indexed map sheets, covered mineral potential areas Reports are available Some of map sheets are available in digital form (MapInfo) The results from new field geological mapping program are produced directly in digital form and printed Only Bulgarian edition available.
Digital Maps, example.
Geological Data Sets Geological Maps, Scale - 1: ,1: ,1: GIS format - different layers of information: –Geological boundaries –Stratigraphy –Lithology –Tectonics –Rivers –Infrastructure - towns, roads, railway
Geomorphologic Map of Bulgaria Scale 1: Unpublished map series Map sheets correspond to geological map in scale 1:
Geochemical Map of Bulgaria Scale 1: Unpublished series, presents point-source geochemical data The point data have been gridded to create colour classified digital maps. Gravity Map of Bulgaria Scale 1: Unpublished map series Bouguer anomaly contours and location of observations
Magnetic Map of Bulgaria Scale 1: Unpublished map series Ground magnetic anomaly contours and location of digitised data points.
Map of Mineral Deposits of Bulgaria, Scale 1: Unpublished map series, consists of point objects that represent location of mineral deposits, occurrence and indication.Geoarchive Data set in Bulgarian language about all the reports available in National Geofund with the key words for searching Oil and Gas Wells Data set for all oil and gas wells drilled on the territory of Bulgaria, onshore and offshore Seismic Lines in Bulgaria Data set consists of information from seismic surveys, onshore and offshore.
Example of interpretation using information from seismic survey, wells and well logs.
Aeromagnetic and Gamma Ray Spectrometer Data Regional aero data Location of digitised data points along flight lines and calculated values of magnetic field and U,Th, K
Exploration Drillholes and Mining Workings Data set consists of information from drillholes and mining workings of mineral exploration programs. National Balance of Reserves and Resources The data set consists of reserves and resources of all metallic, industrial minerals, oil and gas, coal deposits in Bulgaria. Tectonic Map of Bulgaria Scale 1: Published map 2 sheets Bulgarian-English Edition, 1976.
Digital Map Magnetic Map of Bulgaria, 1: Contour map of Za(nT), produced from grid 5x5km
Geological Data Sets Metallogenic Map of Bulgaria, 1: Published 1coloured map sheet, English edition, 1989 Map of Delimited Areas of Gold Deposits in Bulgaria. Computer map, produced from digitised series of maps of scale ranging from 1:1000 to 1: Map of Uranium Mineralization in Bulgaria. Computer Map with uranium deposits, occurrences and radioactive anomalies, digitised from maps of scale 1:
Geological Data Sets Physical properties of the Rocks. Data set containing information for rock samples- coordinates, type of rock, geologic end tectonic position and major physical properties. Currently updated. Pan sampling data. Data set contains information about position of pan samples and quality and quantity of minerals. Currently updated.
