Abstract
The mineralogical and geochemical characteristics of Quaternary sediments from the Bruna and Pecora Valleys (southern Tuscany) were determined, and a study of fluid inclusions found in detrital quartz was carried out. The data suggest the presence of a complex hydrothermal system, located at different depths, that could potentially mineralize several hundred meters of crust. The subsequent dismantling of the mineralized rocks would result in an As anomaly of regional importance, affecting most Quaternary deposits cropping out in southern Tuscany and the marine sediments off the coast of Piombino up to Elba Island.
