  abstract = {{T}he {C}ordillera {B}lanca batholith (12-5{M}yr) forms the highest {P}eruvian summits and builds the footwall of the {C}ordillera {B}lanca normal fault ({CBNF}). {E}ven if several models have been proposed, the processes driving both the exhumation of the {C}ordillera {B}lanca and extensional deformation along the {CBNF} are still debated. {H}ere we quantify the emplacement depth and exhumation of the batholith of the northern {P}eru arc from the late {M}iocene to present. {B}ased on a compilation of crystallization ages and new thermobarometry data in the {C}ordillera {B}lanca batholith, we propose that the batholith was emplaced at a depth of similar to 3km in successive sills from 14 to 5{M}a. {B}y contrast, the younger rocks exposed at the surface were emplaced the deepest (i.e., similar to 6km) and are located close to the {CBNF}, suggesting post 5{M}a tilting. {F}urthermore, a formal inversion of the thermochronologic data indicates an increase of the exhumation rates in the {C}ordillera {B}lanca during the {Q}uaternary. {T}he higher predicted exhumation rates correlate with areas of high relief, both in the northern and central part of the {C}ordillera {B}lanca, suggesting that {Q}uaternary valley carving by glaciations have a significant impact on the latest stage of the {C}ordillera {B}lanca exhumation (2-0{M}a).},
