The In Ezzane volcanic field lies in SE Algeria, near the border with Niger. The alkaline In Ezzane volcanic field, part of which extends into Niger, covers about 500 sq km at the eastern end of Hoggar (Ahaggar) volcanic province and was assigned a Recent age (Liegeois et al., 2005). This poorly known and isolated volcanic field was erupted through basement rocks at the western end of the Saharan meta-craton.

The Global Volcanism Program is not aware of any Holocene eruptions from In Ezzane Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the In Ezzane Volcanic Field page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for In Ezzane Volcanic Field.

This NASA Landsat Thematic Mapper mosaic shows the In Ezzane volcanic field along the border region of Algeria and Niger. The alkaline In Ezzane volcanic field, with lava fields appearing blue-gray in this image, covers about 500 sq km at the eastern end of Hoggar (Ahaggar) volcanic province. This poorly known and isolated volcanic field was erupted through basement rocks at the western end of the Saharan meta-craton.

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.
