The isotope (δD, δ18O, 3H, δ13C, 14C) and chemical (B, Cl) compositions of cold (streams, rivers, soil- and groundwater) and low-temperature geothermal water from northern Iceland were investigated in order to delineate the origin, mixing, water-r

Groundwater in the Lake Myvatn area, northern Iceland: Chemistry, origin and interaction

Autor: Halldór Ármannsson, Hrefna Kristmannsdóttir

Publikováno v: Aquatic Ecology. 38:115-128

Lake Myvatn, northern Iceland is unique in that almost all the inflow is supplied through the groundwater by artesian springs. Hardly any surface water is encountered in the area which is covered by young and porous lava fields and transected by faul
