San Jerónimo volcano

It is a monogenetic volcano like Negro de Chorrillos.[2] It formed on top of ignimbrites of Miocene age[1] of the Aguas Calientes caldera about 780,000 ± 100,000 years ago and is formed by lava, lava bombs and scoria.[3] The volcano erupted basaltic-trachyandesitic lava which propagated to distances of 8–10 kilometres (5.0–6.2 mi) from the vent.[4]

San Jerónimo is a volcano in Argentina.

San Jerónimo is part of a 170 kilometres (110 mi) long alignment of volcanoes along the Calama-Olacapato-El Toro fault. This string of volcanoes is diverse, including calderas and stratovolcanoes on the one hand and plutons and monogenetic volcanoes on the other hand.[5] One volcano that is part of this structure is Aguas Calientes caldera,[2] on whose border the San Jerónimo volcano is constructed.[1]
