CD-CAT is a 5-year (2011-16) project funded by the National Science Foundation, and has the main goal of investigating the surface-to-mantle dynamics of Anatolia (Turkey) during the transition from collision to escape tectonics in the Cenozoic.
Major questions are:
During the development of escape tectonics, what are the plate dynamics from the mantle to the Earth's surface, the origin and consequences of magmatism, the timing and mechanisms by which distributed strain became localized in large strike-slip faults, and the evolution of relief and landscape?
What are the effects of boundary conditions (collision of the Arabian plate to the east, extension of the Aegean to the west, subduction of the Aegean and Cyprian slabs below the Anatolian lithosphere) on the driving forces of tectonic escape?
We are integrating results from many different methods: passive seismic experiments (2-years - see the deployed stations below), magnetotelluric profiling; geomorphic, structural, and stratigraphic-sedimentological analysis of surface geology and exhumed orogenic crust; geo-thermochronometric determination of temperature-time histories of magmatic, metamorphic, and fault zone rocks, basins, and geomorphic markers; isotopic fingerprinting and dating of magmatic rocks; and 2D and 3D numerical modeling.

This project also involves the education and training of graduate students and postdoctoral researchers; international collaboration among researchers in the US, Turkey, Canada, Germany, and Australia; and acquisition of data relevant to understand seismic and volcanic hazards.
