Atakor has erupted basalts, phonolite and trachyte.[1] The basalts are characterized by alkali basalts and basanite and form about 80% of all volcanic rocks in Atakor, with less important occurrences of benmoreite, hawaiite, mugearite and rhyolite.[6] Phenocrysts in some volcanic rocks include amphibole, clinopyroxene, olivine and zircon.[20] The volcanic rocks appear to ultimately derive from mantle plume melts.[30]
