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 poor. Luster of Phonolite is greasy to dull and its fracture is conchoidal to uneven. Phonolite is translucent to opaque in nature.
