  abstract = {{W}e discuss the relationships between {A}ndean shortening, plate velocities at the trench, and slab geometry beneath {S}outh {A}merica. {A}lthough some correlation exists between the convergence velocity and the westward motion of {S}outh {A}merica on the one hand, and the shortening of the continental plate on the other hand, plate kinematics neither gives a satisfactory explanation to the {A}ndean segmentation in general, nor explains the development of the {B}olivian orocline in {P}aleogene times. {W}e discuss the {C}enozoic history of horizontal slab segments below {S}outh {A}merica, arguing that they result from the subduction of oceanic plateaus whose effect is to switch the buoyancy of the young subducting plate to positive. {W}e argue that the existence of horizontal slab segments, below the {C}entral {A}ndes during {E}ocene-{O}ligocene times, and below {P}eru and {N}orth-{C}entral {C}hile since {P}liocene, resulted (1) in the shortening of the continental plate interiors at a large distance from the trench, (2) in stronger interplate coupling and ultimately, (3) in a decrease of the trenchward velocity of the oceanic plate. {P}resent-day horizontal slab segments may thus explain the diminution of the convergence velocity between the {N}azca and {S}outh {A}merican plates since {L}ate {M}iocene.},
