Geology element, Tectonics and Hydro-geology, Minerals and Rocks.
Mines and Quarries. Mineral Ore from pits: a) Dimension stones for Shops and Crushing stones (Marbles, Travetinos, Granite, Limestone); b) Building and construction Stones: 1) crushed stones for concrete and compo (Sands, Gravel, crushing Grout); 2) Bricks and Ashler; 3) Crushed Ores and reef Blocks; c) Industrial feedstock (siliceous sands, Diatoms, Kieselguhrs, artful Marl, Dolomites, etc). The geological associations, Mineral assets and bench. The Mining layer, Opencast Pits and Underground Pits. The Disclosing Ratio. The geo-morphology and the Pits’ characteristics.
The Mining activities planning and localization: the all-over exploitation and the Exploitation-Poles; Environmental Impact from Mining Activities and Environmental Impact Assessment.
