Abstract Analogue models are used to investigate the development of periodic instabilities during a wide rifting mode of continental extension. The results of modeling support that unstable lithospheric extension is accompanied by development of regularly spaced structures at two characteristics wavelengths: a crustal (shorter) wavelength and mantle (longer) wavelength. Both wavelengths are dependent on the brittle/ductile decoupling (i.e., dominance of the brittle rheology of the upper crust over the ductile behavior), as an increase in the brittle layer thickness and a decrease in the extension velocity (decreasing the ductile resistance) lead to an increase in both crustal and mantle wavelengths.
