From Wikipedia, the free encyclopedia

Tephriphonolite is a mafic to intermediate extrusive igneous rock in composition between phonotephrite and phonolite.[1] It contains 9 to 14% alkali content and 48 to 57% silica content (see TAS diagram).[2]

Tephriphonolite has been found, for example, at Colli Albani volcano, Italy[3] and in the Asuncion Rift, Paraguay.[4]
