Geological Summary

A group of cinder cones and associated lava flows SW of the town of Zapala at the southern end of the Loncopue graben form the Laguna Blanca volcanic field. A morphologically pristine cinder cone on the northern shore of Laguna Blanca is a prominent feature of the Laguna Blanca National Park, noted for its aquatic bird fauna, including black-necked swans and flamingos. The youthful-looking basaltic to trachyandesitic cinder cones and small shield volcanoes are considered to be of Holocene age, although no radiometric ages are available.

The Global Volcanism Program is not aware of any Holocene eruptions from Laguna Blanca. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Laguna Blanca 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.
