Open AccessWhat can we learn from geothermobarometry at the dacitic Doña Juana Volcanic Complex (Colombia)? Implications for understanding Pleistocene crystal mushes and pre-eruptive storage conditions in the Northern Andes
We present a reconstruction of the physicochemical conditions of melts in the Pleistocene storage and plumbing system of the Doña Juana Volcanic Complex (SW Colombia): a poorly known, potentially active polyge...

The temporal evolution of monogenetic volcanism in the Central Andes: 40Ar/39Ar geochronology of El Negrillar volcanic field, Chile
El Negrillar volcanic field has the largest extent and erupted volume (~ 6.8 km3 DRE) of all the monogenetic centers of the Andean Central Volcanic Zone (CVZ). The volcanic field comprises 51 eruptive centers and...

The historical case of Paricutin volcano (Michoacán, México): challenges of simulating lava flows on a gentle slope during a long-lasting eruption
Simulating lava flows on a gentle slope is complex since they can propagate in a wide range of directions. It is an even greater challenge to define lava flow trajectories when an eruption lasts over several y...

Open AccessCrystals reveal magma convection and melt transport in dyke-fed eruptions
The processes and ranges of intensive variables that control magma transport and dyke propagation through the crust are poorly understood. Here we show that textural and compositional data of olivine crystals ...

The ~ AD 500–700 (Late Classic) El Astillero and El Pedregal volcanoes (Michoacán, Mexico): a new monogenetic cluster in the making?
The recent identification of Holocene volcanic clusters in small areas within the Michoacán Guanajuato Volcanic Field (MGVF) opens several questions regarding future volcanic hazard assessments in this region....

40Ar/39Ar constraints on the temporal evolution of Graciosa Island, Azores (Portugal)
Lava flows spanning the eruptive record of Graciosa Island (Azores archipelago) and a gabbro xenolith were dated by 40Ar/39Ar in order to constrain the Pleistocene and Holocene volcanic evolution of the island. T...
