Summary

Description
English: This NASA Landsat image shows small scoria cones and lava flows of the Manzaz volcanic field in the Hoggar (Ahaggar) volcanic district of Algeria. The volcanic field covers an area of 1500 sq km, overlying Precambrian metamorphic and plutonic rocks of the Tuareg shield. Many cones are breached, and the dominantly basaltic and basanitic volcanic products are rich in peridotite and pyroxenite xenoliths and megacrysts. The youngest volcanoes rest on Neolithic terraces and are of Holocene age.
