What Lies Beneath?
As climate continues to change and Iceland’s icecaps continue to thin, there is increasing concern about the impacts on subglacial volcanic systems and resulting hazards. To what extent are silicic materials associated with active volcanoes under Vatnajökull (Iceland)? How old are they, how did they form, and how do the geochemical characteristics of these systems’ silicic materials compare to those in the known rock record elsewhere in Iceland? What hazards do silicic magmas present in this dynamic rift-mantle plume-ice environment? [with student L. Driggs] |
