  abstract = {{T}he impact of subduction processes on surface uplift and relief building in the {A}ndes is not well understood. {I}n northern {P}eru, we have access to a modern flat subduction zone (3 degrees-15 degrees {S}) where both the geometry and timing of the flattening of the slab are well constrained. {S}ome of the highest {A}ndean peaks, the {C}ordillera {B}lanca (6768 m) and the {C}ordillera {N}egra (5187 m), are located just above the {P}eruvian flat slab. {T}his is a perfect target to explore the impact of slab flattening and associated magmatism on {A}ndean topography and uplift. {W}e present new apatite ({U}-{T}h)/{H}e and fission-track data from three vertical profiles in the {C}ordillera {B}lanca and the {C}ordillera {N}egra. {T}ime-temperature inverse modeling of the thermochronological data suggests that regional exhumation in the {C}ordillera {O}ccidental started at ca. 15 {M}a, synchronous with the onset of subduction of the {N}azca {R}idge and eastward movement of regional magmatism. {W}e propose that ridge subduction at 15 {M}a and onset of slab flattening drove regional surface uplift, with an important contribution of magmatism to relief building in the {C}ordillera {O}ccidental.},
