This study aims to explore the extent and controls of silicon isotope fractionation in hot spring systems of the Geysir geothermal area (Iceland), a setting where sinter deposits are actively formed. The δ 30 Si values of dissolved silica measured in the spring water and sampling sites along outflow...
