侵蚀模式和速率的33个成层火山在干旱到超干旱的中部安第斯火山带（14 S至27 S）已受到形态计量模型的约束。所有选定的火山属于短命的，对称的，圆形安山质层锥型，年龄跨越14马到最近。从这种类型的初始年轻火山形态开始，在我们的研究中以帕里纳科塔火山为代表，并比较逐渐侵蚀的火山的重建体积，这样的时间跨度使我们能够推断长期侵蚀率。典型的侵蚀率
Erosion patterns and rates of 33 stratovolcanoes in the arid to hyperarid Central Andean Volcanic Zone (14 S to 27 S) have been constrained by morphometric modelling. All selected volcanoes belong to the short-lived, symmetrical, circular andesitic stratocone type, with ages spanning 14 Ma to recent. Starting from the initial, youthful volcano morphology of this type, represented in our study by Parinacota volcano, and comparing reconstructed volumes of progressively eroded volcanoes, such a time span allows us to infer long-term erosion rates. Typical erosion rates of
