Formation

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

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Phonolite vs Pumice Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Phonolite and Pumice Reserves. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Phonolite vs Pumice information and Phonolite vs Pumice characteristics in the upcoming sections.

More about Phonolite and Pumice

Here you can know more about Phonolite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Pumice consists of mineral content and compound content. The mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Phonolite vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Phonolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Phonolite is Banded and Foilated and that of Pumice is Vesicular. Properties of rock is another aspect for Phonolite vs Pumice. The hardness of Phonolite is 5.5-6 and that of Pumice is 6. The types of Phonolite are Kenyte whereas types of Pumice are Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite is white while that of Pumice is white, greenish white or grey. The specific heat capacity of Phonolite is 0.84 kJ/Kg K and that of Pumice is 0.87 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Phonolite is heat resistant, impact resistant, wear resistant whereas Pumice is impact resistant, pressure resistant.
