Global Tectonics with Deformable Plates

Abstract

In the previous chapter we analysed the limitations of rigid plate tectonics or standard theory. In this chapter, we will try to prove that these limitations can be overcome if we relax the postulate of plate rigidity for oceanic lithosphere due to hydrothermal seafloor metamorphism. The deformation mechanisms responsible for the strain regime in oceanic lithosphere are revised by A. Mateus in the section 3.12. We will analyse the evidence for aseismic strain in oceanic lithosphere, both by boudinage and homogeneous shortening. We will review the evidence for buckling of both oceanic and continental lithosphere.
