Thrust ramps within MTDs initiate within competent horizons in the hangingwall of the underlying detachment. Within MTDs, the spacing of thrust ramps and thickness of the thrust sequence display a ∼5:1 ratio. Thrust systems within MTDs display greater variations in hangingwall and footwall cut-offs (or stretch) than in lithified rocks. Thrust systems within MTDs broadly ‘balance’, although heterogeneous lateral compaction increases by ∼10% towards the surface. Critical taper angle in MTDs may be an order of magnitude less than in accretionary complexes and lithified rocks.
