Deformation patterns in the southwestern part of the Mediterranean Ridge (South Matapan Trench, Western Greece)Deformation patterns in the southwestern part of the Mediterranean Ridge (South Matapan Trench, Western Greece) Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2018-03-052017enSeismic reflection data and bathymetry analyses, together with geological information, are combined in the present work to identify seabed structural deformation and crustal structure in the Western Mediterranean Ridge (the backstop and the South Matapan Trench). As a first step, we apply bathymetric data and state of art methods of pattern recognition to automatically detect seabed lineaments, which are possibly related to the presence of tectonic structures (faults). The resulting pattern is tied to seismic reflection data, further assisting in the construction of a stratigraphic and structural model for this part of the Mediterranean Ridge. Structural elements and stratigraphic units in the final model are estimated based on: (a) the detected lineaments on the seabed, (b) the distribution of the interval velocities and the presence of velocity inversions, (c) the continuity and the amplitudes of the seismic reflections, the seismic structure of the units and (d) well and stratigraphic data as well as the main tectonic structures from the nearest onshore areas. Seabed morphology in the study area is probably related with the past and recent tectonics movements that result from African and European plates’ convergence. Backthrusts and reverse faults, flower structures and deep normal faults are among the most important extensional/compressional structures interpreted in the study area.http://creativecommons.org/licenses/by/4.0/Marine Geophysical Research1-16 Andronikidis Nikolaos Ανδρονικιδης Νικολαος Kokinou, Eleni Manoutsoglou Emmanouil Μανουτσογλου Εμμανουηλ Vafeidis Antonios Βαφειδης Αντωνιος Καμπέρης Ευάγγελος Kamberis Evangelos Springer Publishing Company Deformation patterns Inner Mediterranean Ridge Seafloor Seismic structure Tectonics
