Geochemistry and potential use of groundwater in the Rocca Busambra area (Sicily, Italy)
2008
In the Rocca Busambra area (mid-west Sicily, Italy), from November 1999 to July 2002, 23 water points including wells and springs were sampled and studied for their chemical and isotopic compositions. Two rain gauges were also installed at different altitudes, and rainwater was collected monthly to determine the isotopic composition. The obtained results revealed the Rocca Busambra carbonate complex as being the main recharge area on account of its high permeability value. From a chemical view point, two main groups of water can be distinguished: calcium–magnesium–bicarbonate-type and calcium–magnesium–chloride–sulphate-type waters. The first group reflects the dissolution of the carbonate …
Land Cadastre in Italy for Sustainable Development: Application to Two Parcels of Land in a Geopark in the Process of Being Defined in Corleone (PA-I…
2020
Geoparks, like all parks, are UNESCO awards for a sustainable management of all resources and therefore also of human life. Environmental emergencies such as climate change, pollution, soil erosion, salinisation, and fires that, together with health emergencies, undermine life on earth, require intervention. The widespread sustainable management of the territory of a municipality, a region, a nation, or all of them (European Union) allows to widen the application of these concepts to reach the limit of a planet that guarantees life for future generations. The work after having exposed the motivations of the geopark (an initiative born by chance), i.e. the surface where the environmental bea…
Episodic deposition of the Lias in the Medianes nappe (western Switzerland): a record from mineralized ammonite-bearing beds
1992
Abstract Sinemurian and Pliensbachian depositional sequences from the starved distal northern continental margin of the Tethys are preserved in the Medianes Nappe (Western Swiss Prealps). They contain mineralized beds which include a variety of facies. The northern continental margin of the Tethys was broken into blocks, less than 50 km wide, during an extensional phase. The Sinemurian and Pliensbachian sediments in the study are vary in thickness from less than 50 m in the north to more than 200 m in the south. Although the upper Sinemurian to Pliensbachian mineralized beds are thin, between 0.10 and 0.50 m thick, they commonly contain several distinct faunal horizons stacked one upon anot…
