岩石圈滴现象已经在全球不同地区得到解释，以解释大陆岩石圈的再循环和高原的快速隆起。然而，在地质、地球物理和岩石学观测的背景下，这种假设的有效性并没有得到很好的证明，这些观测是根据地球动力学模型进行检验的。本文认为，中安纳托利亚（Kırşehir）弧的褶皱导致岩石圈增厚，弧根部开始“滴水”。我们的地球动力学模型解释了地震资料显示的岩石圈缺失和一个具有滴水弧根特征的残余结构，以及整个高原上神秘的bbbb1 km隆升，高原南缘和北缘的卡帕多西亚和加拉提亚火山活动分别自~10 Ma以来。模型表明，在水滴演化过程中，随着垂直载荷和地壳变形的变化，弧根的移除产生了初始地表沉降，使地表隆起逆升>.1 km。大陆岩石圈的再循环和高原的快速隆升被认为是岩石圈滴水的结果，但没有自然的例子。在此，作者利用地球动力学模型提出了中安纳托利亚弧的褶皱和增厚导致了弧根的岩石圈滴水。
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 (Kırşehir) 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. The recycling of continental lithosphere and rapid plateau uplift is believed to be the result of lithospheric drips, but natural examples are missing. Here, the authors use geodynamic models to suggest that the folding and thickening of the Central Anatolian arc caused lithospheric dripping of the arc root.
