Crustal disequilibrium of the central Pontides (northern Turkey) due to oroclinal bending revealed by gravity modelling


JOURNAL OF ASIAN EARTH SCIENCES, vol.186, 2019 (SCI-Expanded) identifier identifier


The Turkish Pontide orogenic belt belongs to the former Eurasian margin, which is the result of two major successive processes of the closure of the Tethyan oceans: subduction followed by collision. This almost E-W trending large mountain range shows an arc-shaped geometric structure in the northern Turkey. According to previous studies based on geological and paleomagnetic data, oroclinal deformation was proposed as a result of the geodynamic evolution due to the Africa-Eurasia convergence in the region. The aim of study is to determine how this important evolution is expressed in the lithosphere beneath the region by gravity modelling.
