Geological and mining historical facts:
- Main mineralization of the deposits: karst bauxite, dominated by boehmite
- Other geological features: presence of kaolinite, silica-bearing and ferroginous nodules
- Deposit types and thickness: white (poor in SiO2, rich Al2O3) and red (rich in Fe2O3) bauxite; 20 m thick
- Mining activity: 1950-1978
- Presence of processing besides the mining area: no
- Current use of the area: natural park
Project activities:
Techical visit - July 2020
- Permission from Alta Murgia National Park;
- Survey of the area;
- Collection of in situ samples;
- Topographic analysis for reconstruction of volumes of tailings;
- Spectroradiometer analysis for further integration with satellite images.
Lab analysis - Autumn 2020
- XRF analysis - performed by Department BIGEA of UNIBO;
- SEM and EDS - performed by SSPT-PROMAS of ENEA.
Topographic survey - May 2021
- Visual inspection and checks of areas around the abandoned mining area identified by hyperspectral bands
- Topographic and spectroradiometer analysis in poromising points, confirmed by visual inspection
- Collection of few samples around the abandoned mining areas in promising points
Potential case study analysed by: University of Bologna, with the support of ENEA
