Formation
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Phonolite vs Laterite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Phonolite vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phonolite and Properties of Laterite. Learn more about Phonolite vs Laterite in the next section. The interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Phonolite and Laterite, they have various applications in construction industry. The uses of Phonolite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Phonolite and Laterite
Here you can know more about Phonolite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phonolite and Laterite 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 Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Phonolite vs Laterite, 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, Laterite is available in brown, buff, red colors. Appearance of Phonolite is Banded and Foilated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Phonolite vs Laterite. The hardness of Phonolite is 5.5-6 and that of Laterite is 2. The types of Phonolite are Kenyte whereas types of Laterite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phonolite and Laterite is white. The specific heat capacity of Phonolite is Not Available and that of Laterite is Not Available. 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 Laterite is heat resistant, pressure resistant.
