Buckling of the oceanic lithosphere from geophysical data and experiments
Buckling of the oceanic lithosphere from geophysical data and experiments
Two major hypothesis have been advanced for the formation of the long wavelength (100-300) km undulations of oceanic basement and overlying sediments developed in the central Indian Ocean: whole layer folding (buckling) and local thickening (inverse boudinage). Using appropriately scaled two layer models of the oceanic lithosphere comprising a brittle layer overlying a ductile lower layer, we show that buckling of the entire brittle layer is likely to be the mode of deformation. However the lithosphere-asthenosphere boundary remains undisturbed. We find a relationship between the thickness of the brittle layer and the wavelength of folding such that the wavelength is 7 times the brittle layer thickness.

Abstract
Two major hypothesis have been advanced for the formation of the long wavelength (100-300) km undulations of oceanic basement and overlying sediments developed in the central Indian Ocean: whole layer folding (buckling) and local thickening (inverse boudinage). Using appropriately scaled two layer models of the oceanic lithosphere comprising a brittle layer overlying a ductile lower layer, we show that buckling of the entire brittle layer is likely to be the mode of deformation. However the lithosphere-asthenosphere boundary remains undisturbed. We find a relationship between the thickness of the brittle layer and the wavelength of folding such that the wavelength is 7 times the brittle layer thickness.
