Central (18–28° S) and Southern (33–46° S) Andean Volcanic Zones (CVZ and SVZ, respectively) have several Miocene to Recent collapse calderas. We compare their characteristics based on published data to identify how the tectonic variables have

Publikováno v: Journal of South American Earth Sciences. 90:453-462

The formation of pumice cones by deposition of near-vent pumice fragments is relatively rare in comparison with the occurrence of their mafic equivalents, the scoria cones. The Quaternary Payún Matrú caldera (36° S, 69° W), within the back-arc of

We present a detailed stratigraphy of the Coranzulí caldera-forming deposits. This caldera, located in the Altiplano-Puna Volcanic Complex (Central Andes), generated four ignimbrite deposits with similar field characteristics and facies that differ

The back-arc southern Puna region (south of ~24°S) in the Central Volcanic Zone of the Andes contains hundreds of Miocene to Quaternary mafic monogenetic volcanoes roughly distributed in several volcanic fields. Analysis of the geomorphology, morpho
