 Thick-skinned deformation

Thick-skinned deformation is a geological term used to describe a type of tectonic deformation that primarily affects the upper crust of the Earth, where the deformation occurs mainly through the movement and interaction of large blocks of lithosphere. This process is typically associated with compressional forces, where the Earth's crust is pushed together, resulting in significant folding, faulting, and the uplift of rock masses.
