The evolution of hydrothermal alteration in glassy and variably palagonitized tuff, erupted as tephra in 1963 – 1964 on Surtsey, an island built in the offshore extension of Iceland’s southeast rift zone, is documented through a comparative petrographic study of samples from drill cores recovered in...
