the project is to reconstruct the geometry of the spreading system and
the paleospreading direction in the western Tethyan Ocean through the
paleomagnetic analyses of dyke complexes of the Turkish ophiolites. We
know that the convergence between Europe and Africa in the Cretaceous
was roughly N-S-oriented.

reconstructing the geometry of the ridge
system in the same time span we can infer if the subduction started at
the ridge or at the transform fault. Each scenario requires a different
geodynamic mechanism and driving forces that will be discussed to
interpret the obtained data. Such
a reconstruction is then integrated into a larger
scale geological scenario to
elaborate mechanisms of subduction initiation.
