  abstract = {{I}n the northern {A}ndes, the {E}cuadorian arc presents a large number of {Q}uaternary volcanoes, spread over a rather restricted area. {T}he origin of this volcanic clustering is not well understood, and only a few chronological data older than the {H}olocene are available in northern {E}cuador to document the arc development stages. {I}n this study, we present new {K}-{A}r ages obtained on lava flow and pumice samples for {C}ushnirumi, {M}ojanda, {F}uya {F}uya, {I}mbabura, {C}ubilche, and {C}usin volcanoes, located about 40 km north of {Q}uito, the {E}cuador's capital city. {O}ur results show that the volcanic activity in the northern part of the {E}cuadorian arc started at least at 1 {M}a and that construction of volcanoes mainly occurred during the last 500 ka. {T}ogether with the radiometric data, numerical reconstructions of the paleomorphology of the volcanoes are used to estimate the volume of emitted magmas and the amount of eroded material in order to quantify their eruptive and erosion rates. {E}mission rates of {E}cuadorian volcanoes range between < 0.2 and 3.6 +/- 2.1 km(3)/kyr. {H}ighest rates are obtained for volcanoes constructed over time periods shorter than 100 kyr by sporadic eruptive pulses, whereas lowest rates are calculated over longer periods that include quiescence phases. {E}rosion rates range between 0.02 +/- 0.01 and 0.14 +/- 0.09 km(3)/kyr and highlight that volcanic edifices whose activity ended recently are rapidly dismantled by physicochemical processes. {F}inally, the spatial distribution of {Q}uaternary volcanoes as well as the spatio-temporal evolution of lava geochemistry may reflect the progressive influence of the {C}arnegie {R}idge at depth. {G}raphical abstract},
