On the 27-29th September of 2015 we carried out our first field work in the nearby alkaline springs in the Ronda peridotites of the Betics (Province of Malaga, SW Spain). The goal of the field trip was to observe the geological features of the area, and explore the different serpentinization-related alkaline spring sites. We visited numerous alkaline springs in the wider area of the peridotites, and we conducted preliminary on site measurements of water temperature, pH, Eh and total dissolved solids. We collected several liters of natural hyperalkaline water (pH > 11.5) in order to perform experiments of fluid–rock interaction experiments in the lab using a flow-through reactor.
