Abstract

Lithospheric drips have been interpreted for various regions around the globe to account for the recycling of the continental lithosphere and rapid plateau uplift. However, the validity of such hypothesis is not well documented in the context of geological, geophysical and petrological observations that are tested against geodynamical models. Here we propose that the folding of the Central Anatolian (Klrşehir) arc led to thickening of the lithosphere and onset of "dripping" of the arc root. Our geodynamic model explains the seismic data showing missing lithosphere and a remnant structure characteristic of a dripping arc root, as well as enigmatic >1 km uplift over the entire plateau, Cappadocia and Galatia volcanism at the southern and northern plateau margins since ~10 Ma, respectively. Models show that arc root removal yields initial surface subsidence that inverts >1 km of uplift as the vertical loading and crustal deformation change during drip evolution.

O.H.G. also thanks to Istanbul Technical University (ITU BAP) for financial support. R.N.P. acknowledges funding from an NSERC Discovery Grant. Numerical calculations were done using a modified version of the SOPALE (2000) software. The SOPALE modeling code was originally developed by Phillup Fullsack at Dalhousie University with Chris Beaumont and his Geodynamics group. We thank Greg Houseman and Taras Gerya for their careful reviews. We benefited from useful discussions with our colleagues Cengiz Yıldırım, Aral Okay, Attila Çiner, Ebru Şengul-Uluocak, Yücel Yılmaz, and Gültekin Topuz on the geology and uplift of the Central Anatolia
