Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic
From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

Archaeological Significance
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Learn more about Properties of Phonolite
What is Phonolite? In this section, we will learn more about properties of Phonolite i.e. physical and thermal properties. Physical properties of Phonolite include Color, Streak, Hardness, Structure, Cleavage, Fracture, Luster, Specific Gravity etc. The strength of Phonolite is 150.00 N/mm2. Streak of Phonolite is white while its cleavage is . Luster of Phonolite is greasy to dull and its fracture is conchoidal to uneven. Phonolite is translucent to opaque in nature.
