The Upper Orobic Nappe is the uppermost and oldest thin-skinned thrust sheets of the eastern South Alpine domain. It consists of an around 5 to 7 km thick basement sheet, arranged in a series of en-échelon anticlines. The thrusts associated with the Upper Orobic Nappe ramped into the sedimentary cover, creating several duplexes that occur in a belt of klippes. The distribution of these erosional remnants reflects the later deformation by the basement ramps of the underlying younger local thrust sheets and imbricates (Lower Orobic Imbricates).

The Lower Orobic Imbricates encompasses units of the median part of the thin-skinned thrust sheets of the eastern South Alpine domain. The en-échelon arrangement of its ramp anticlines is similar to that of the overlying Upper Orobic Nappe with a more diffuse deformation in the sedimentary cover. A large part of the Bergamasc Alps and of the Giudicarie region belongs to this unit.
