  • Presented numerical models of continental subduction and collision reproduce the relamination process for a range of conditions
  • Relamination may occur directly into the crust for very weak overriding plates or through the overriding plate lithosphere
  • Deep subduction and relamination through the overriding plate lithosphere is typical for quickly colliding young continents

Evidence for 1.5 km of Uplift of the Central Anatolian Plateau's Southern Margin in the Last 450 kyr and Implications for Its Multiphased Uplift History

Nazik Öğretmen,  Paola Cipollari,  Virgilio Frezza,  Costanza Faranda,  Konstantina Karanika,  Elsa Gliozzi,  Giuditta Radeff,  Domenico Cosentino, 
  • Pages: 359-390
  • First Published: 06 January 2018
Key Points

  • The youngest marine deposits capping the central Taurides at elevations between 1,000 to 1,500 m are middle Pleistocene in age
  • The maximum age for the youngest marine deposits at the southern margin of the plateau implies uplift rates of 3.21 to 3.42 mm/yr
  • This work suggests that the multiphased uplift of the area can be linked to lithosphere delamination and subsequent slab breakoff
