In regions of neotectonic activity geothermal waters flow into extensional fissures and deposit successive layers of carbonate as fissure travertine incorporating small amounts of ferromagnetic grains. The same waters spill out onto the surface to deposit bedded travertine, which may also incorporate wind-blown dust with a ferromagnetic component. Travertine deposits are linked to earthquake activity because geothermal reservoirs are reset and activated by earthquake fracturing but tend to become sealed by deposition of carbonate between events. A weak ferromagnetism records the ambient field at the time of deposition and sequential deposition can identify cycles of secular variation of the...

The Geodynamics of the Aegean and Anatolia
The complexity of plate interactions and associated crustal deformation in the Eastern Mediterranean region is reflected by the numerous destructive earthquakes that have occurred throughout its history. Many of these have been well documented and studied. In addition, the Aegean region provides examples of core-complex formation, synchronous basin evolution and subsequent graben formation and continental extensional deformation following orogenic contraction. It is therefore considered to be a perfect natural laboratory for the study of these mechanisms. The region has been the subject of intensive research for several decades. This book contains current results and ideas regarding the geodynamics of the Aegean and Anatolia. It will be essential reading for all geoscientists with an interest in the structural evolution of the Eastern Mediterranean.
