Geological Summary

Infiernillo, a late-Pleistocene to Holocene basaltic-andesite volcanic field along the Río Salado in Argentina lies about 70 km east of the crest of the Andes and NW of the town of Malargüe. Several vents controlled by extensional tectonics produced lava flows with prominent flow features that reached to the river. A radiocarbon date of about 8840 yrs Before Present was obtained from Volcán Hoyo Colorado.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
