Geological development of a gypsum lake formed at the beginning of the 2oth century in central Sicily, Italy: Integration of historical data with mod…
2006
A limnological investigation was carried out on the small, endorheic lake, called Lake Sfondato, located in central Sicily (Italy). All the aquatic environments in the central part of the island are rich in salt, with conductivity values above 5 mS cm−1, and are characterized by high alkalinity values and hard waters. In addition, due to intensive agriculture, many of these ecosystems have experienced a strong anthropogenic eutrophication over the last decades. In order to better understand the functioning of these peculiar environments, the morphology, hydrology, and geochemistry, as well as several selected physical and biological characteristics of Lake Sfondato, were studied in the year…
The Permocarboniferous Basin and Range Province of Europe. An Application op Plate Tectonics
1976
Distribution and development of European late Hercynian intermontane troughs and associated volcanicity are related to an upper mantle diapir which formed above two subduction zones during the Hercynian cycle of orogenesis. Lateral spreading of the diapir caused regional extension of the previously folded crust and enabled tholeiitic magmas from the upper mantle and rhyolitic magmas from the lower crust to reach the surface.
