Analysis of complex geodynamic interactions in the eastern part of Central Gondwana and Eurasia

The eastern part of Central Gondwana and Eurasia is a tectonically complex region where several large tectonic plates interact -Eurasian, African, Arabian, Aegean-Anatolian, Iranian, and Sinai.However, consideration of only these plate interactions is insufficient.In addition to this interface, other regional geodynamic factors exist: the mantle rotating counterclockwise structure (MRCS), the Ural-African geoid anomaly, and the critical Earth latitude 35.The Eurasia-Gondwana boundary divides the western partthe Aegean-Anatolian Plate and Mesozoic Terrane Belt (MTB) associated with the comparatively young Neoproterozoic Beltand the eastern part, the Iranian Plate, whose terranes are fragments of the Archean-Early Proterozoic Arabian craton.The Iranian lithospheric plate, a key player at the boundary between Eurasia and Gondwana, holds significant implications in the tectonic-geodynamic context.It tectonically influenced the South Caspian Basin (SCB) and recently revealed MTB.Novel tectonic, satellite-derived gravity, and magnetic maps of the Iranian Plate have been developed.Geodynamically, the considered tectonic units are located above the central and eastern parts of the MRCS.The Iranian Plate is above the eastern (periclinal) zone of the MRCS and, under its influence, moves northward.The movement of the western part and complex form of the Iranian Plate force the clockwise rotation of the SCB.A complex geodynamicgeophysical interaction of the central tectonic-geodynamic units in the region is shown.The influence of the recent geodynamic event -Akchagylian hydrospheric maximum on the ancient hominin dispersal in the region is exhibited.The carried analysis is essential to understand the role of the complex geodynamic interface in a transition zone between Eurasia and Gondwana.
