The Crater Basalt volcanic field in the northern Patagonia region of Argentina covers an area of about 700 sq km. The volcanic field lies about 400 km east of the Peru-Chile trench along the broad regional, NW-SE-trending Gastre fault system. Nine cinder cones and spatter cones produced blocky lava flows of alkali basaltic, basanitic, and trachybasaltic composition. One of the largest features of the volcanic field is Cerro Fermín, a cinder cone that produced a half dozen lava flows. The highest cone, 1344-m Cerro Negro, fed lava flows that traveled to the west, east, and then NE, where its distal margin is cut by a provincial road. Some of the lava flows, such as those from Cerro Ventana and Cerro Contreras, cover Holocene shorelines of playa lakes.
The Global Volcanism Program is not aware of any Holocene eruptions from Crater Basalt Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Crater Basalt Volcanic Field page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

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.
