Dr. Ake Fagereng
Institution: University of Cape Town, Dept. of Geological Sciences
Awards: Elsevier Young Scientist Award P-Rated
Dr. Fagereng is Norwegian, but gained his BSc in Geology and Ocean & Atmosphere Science, and BSc(Hons) in Geology, from the University of Cape Town, South Africa. He then undertook a PhD with Rick Sibson at the University of Otago, working on the structural geology of the Chrystalls Beach Complex, a melange shear zone in the Otago Schist, on the South Island of New Zealand. Observations in this sheared rock assemblage, compared to geophysical observations of the active Hikurangi subduction margin on the North Island, led to a number of publications on the internal structure of the subduction zone interface. In particular, Ake focussed on the effects of rock composition and geometry on the seismic behaviour (big earthquakes vs. aseismic creep) of subduction megathrusts.
After his time on New Zealand, Ake returned to the University of Cape Town to take up a lectureship in structural geology. In this position he has, in addition to keeping up work on the seismic behaviour, slip style, and fluid pressure state of subduction interfaces, worked on strain localization in ductile shear zones (in Namibia and Antarctica), intraplate seismicity (in South Africa), the strength and deformation style of solid-melt mixtures (in Namibia and Antarctica), and the involvement of pre-existing basement structures in the evolution of the East African Rift System. Overall, Ake is interested in all sorts of rock deformation structures, as long as they can be observed in the field, or in collected rock samples under the microscope.
