|a 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.
