Early Miocene large-volume ignimbrites of the Oxaya Formation, Central Andes [PDF]
, 2016 During the early Miocene ignimbrite flare-up, significant parts of the Central Andes (17–20°S) were covered by large-volume ignimbrites. High-precision 206Pb/238U zircon dates constrain the flare-up in northern Chile at c.

Neogene ignimbrites and volcanic edifices in southern Peru: Stratigraphy and time-volume-composition relationships [PDF]
, 2008 In the Central Andes of Peru, four volcanic arcs, termed Tacaza, Lower and Upper Barroso, and Frontal arc, have been active over the past 30 Ma (Fig. 1). They form five units between Moquegua and Nazca (14°30– 17°15’°S and 70–74°W).
