| The conical, glacier-clad Nevado de Longaví volcano is a late-Pleistocene to Holocene, dominantly andesitic stratovolcano constructed over a basement of Tertiary volcaniclastic and granitic rocks. Two edifice-collapse events modified the eastern and SW flank of a pre-Holocene volcano, and Holocene activity has been concentrated at the summit region and on the eastern flanks of the volcano. Andesitic-to-dacitic lava domes occupy the summit region, and a Holocene dome forms the 3242-m-high summit of Longaví. The last eruptions produced a lava dome in the upper part of the collapse scarp and summit region that partially collapsed to the east, forming block-and-ash flow deposits. No historical eruptions are known, although fumarolic activity continues. | |||
