Fig. 11From: Rocks control the chemical composition of surface water from the high Alpine Zermatt area (Swiss Alps)Schöller diagram showing the concentrations of major solutes (ci) in selected surface water expressed as logci in meq L−1. Water types: a CC (Ca-CO3) water, b CCA (Ca-CO3-alkalis) water, c CS (Ca-SO4) water (ZM73 and ZM87) and CSA (Ca-SO4-alkalis) water (ZM78 and ZM 84) water, d MC (Mg-CO3) waterBack to article page
