Miocene to Recent collapse calderas of the southern and central volcanic zones of the Andes and their tectonic constraints
(Springer, 2021-01-30)
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 ...
Reconciling the location of lava domes and eruption centers in Paleocene-Eocene calderas in northern Chile
(2021)
In the Atacama Desert, at the Precordillera of northern Chile, a series of Paleocene-Eocene caldera deposits and ring-faults are exceptionally well-preserved1. Here we aim to build on previous mapping efforts to consider ...
The caldera-forming eruption of the quaternary Payún Matrú volcano, Andean back-arc of the southern volcanic zone
(Elsevier Science, 2019-10)
The Payún Matrú caldera is a Quaternary Andean back-arc caldera (36° 25′ S, 69° 12′ 30? W), and represents the main volcanic edifice of the homonym Payún Matrú volcanic field, located within the Payenia Basaltic province. ...
El Morro caldera (33° 10′ S, 66° 24′ W), San Luis, Argentina: An exceptional case of fossil pre-collapse updoming
(Elsevier Science, 2017-03)
Volcanism at Sierra del Morro represents the final stages of the flat-slab related magmatism in the easternmost San Luis Neogene Volcanic Belt. This ~80 km-long NW-WNW-trending belt tracks the episodic inland migration of ...

Post-caldera pumice cones of the Payún Matrú caldera, Payenia, Argentina: Morphology and deposits characteristics
(Pergamon-Elsevier Science Ltd, 2019-03)
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° ...
