Evolution of fluid chemistry during travertine formation in the Troll thermal springs, Svalbard, Norway
Abstract Arctic hydrothermal springs at Bockfjorden, Svalbard, have isotope and trace element signatures indicative of derivation from glacial melt waters with minor contribution from seawater. Downstream gradients in water chemistry, isotopic composition and carbonate precipitation rates have been...
