Although groundwater is a strategic source in volcanic islands, most hydrogeochemical research on this topic has been focused activity monitoring, overlooking general hydrogeological aspects. The same applies to one of the studied volcanoes world, Stromboli Island (Italy). Here, we provide scheme its coastal aquifer, retrieving inferences about potential use as water supply and for optimizing m...
Progress in understanding mineral evolution, Earth’s changing near-surface mineralogy through time, depends on the availability of detailed information on mineral localities of known ages and geologic settings. A comprehensive database including this information, employing the mindat.org web site as a platform, is now being implemented. This resource will incorporate software to correlate a ran...
