Lateral Ramps in the Folded Appalachians and in Overthrust Belts Worldwide—A Fundamental Element of Thrust-Belt Architecture

A report about lateral ramps which are zones where décollements change stratigraphic level along a strike. This report suggests that many cross-strike features may be underlain by lateral ramps that serve to transfer décollements from one stratigraphic level to another in the same manner as frontal ramp, but in a direction normal to the strike of the fold belt.
