Hydrodynamics in Evaporate-Bearing Fine-Grained Successions Investigated through an Interdisciplinary Approach: A Test Study in Southern Italy—Hydrogeological Behaviour of Heterogeneous Low-Permeability Media

Major ions classification ((a) and (b)) and brine (c) ternary diagrams of the borehole and spring waters sampled at Pozzo del Sale (modified after [17]). In (a) and (b), grey area shows the compositional range of the Messinian Ca-chloride formational fluids from the Northern Apennines (Ca ternary subdiagram in (c) [18]), whereas dashed line represents chemical evolution pathway of a typical evaporite-dissolving groundwater (after [19]). Arrows depict possible mixing trends. Seawater is also shown as comparison.
