Iceland Geodynamics

Crustal Deformation and Divergent Plate tectonics

Freysteinn Sigmundsson

Iceland is the largest part of the mid-ocean ridge system elevated above sea level and, as such, is a unique site for the study of the physical processes of divergent plate tectonics and the consequences of plume-ridge interaction.

Iceland Geodynamics summarises a wealth of information that has been collected but never previously published in one volume. It provides a comprehensive overview of crustal deformation and the physical processes that govern divergent plate tectonics in Iceland. Extensive monitoring of crustal deformation in this unique natural laboratory has led to new results of interest not only to researchers and students particularly interested in Iceland, but also for understanding more generally how volcanoes work.

The emphasis is on results from studies of crustal deformation, and the objective is to place the geodynamical results in their broader context and discuss in general the physical processes of divergent plate tectonics.
