Breaking plates: Creation of the East Anatolian fault, the Anatolian plate, and a tectonic escape system

چکیده
Abstract Lateral movement of lithospheric fragments along strike-slip faults in response to collision (escape tectonics) has characterized convergent settings since the onset plate tectonics and is a mechanism for formation new plates. The Anatolian was created by sequential connection following ≥10 m.y. distributed deformation that ultimately localized into plate-bounding faults. Thermochronology data seismic images lithosphere structure near East fault zone (EAFZ) provide insights development escape system. Low-temperature thermochronology ages rocks EAFZ are significantly younger than other zones region, e.g., apatite (U-Th)/He: 11–1 Ma versus 27–13 Ma. Young (U-Th)/He thermal history modeling record resetting over past ~5 interpreted indicate activity triggered faulting as it formed through-going, lithosphere-scale structure. may be discerned from S-wave velocity Continental Dynamics–Central Tectonics (CD-CAT) experiment.

Crustal structure of the North Anatolian and East Anatolian Fault Systems from magnetotelluric data
Magnetotelluric (MT) studies can map subsurface resistivity structure and have located zones of low resistivity (high conductivity) within major strike-slip fault zones worldwide which have been interpreted as regions of elevated fluid content. This study describes MT data from the eastern part of the North Anatolian and the East Anatolian Fault Systems (NAFS and EAFS) and presents the results ...
متن کاملA comparison between the Kazerun (Iran) and the North Anatolian (Turkey) fault systems in fault interaction and seismicity migration based on the spatiotemporal analysis of earthquakes
The Kazerun Fault System (KFS) is a right-lateral strike slip fault system in the middle part of the Zagros seismogenic zone in Iran. Historical and instrumental earthquake data catalogs of this fault system show good evidence of fault interactions and seismic migrations. This study provides evidence for the migration of seismicity in the middle part of the Zagros region along the segments of t...
متن کاملThe Position of Anatolian
The Position of Anatolian 6.1 History of the Question 6.1.1 Discovery and Recognition Hrozný (1917) showed that the chief administrative language of the Hittite Empire, attested in cuneiform documents from Hattusha in central Turkey dating from the 16th-13th centuries BCE, was Indo-European. Through the work of a number of scholars it was known by the 1930s that Hittite was not alone in ancient...
متن کاملAn aseismic slip transient on the North Anatolian Fault
Constellations of Synthetic Aperture Radar (SAR) satellites with short repeat time acquisitions allow exploration of active faults behavior with unprecedented temporal resolution. Along the North Anatolian Fault (NAF) in Turkey, an 80 km long section has been creeping at least since the 1944, Mw 7.3 earthquake near Ismetpasa, with a current Interferometric Synthetic Aperture Radar (InSAR)-deriv...
