Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic

Etymology
From Latin later brick, tile + -ite1
From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

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

Laterite vs Phonolite 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. Laterite vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Phonolite. Learn more about Laterite vs Phonolite in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Laterite and Phonolite, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Phonolite 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.
More about Laterite and Phonolite
Here you can know more about Laterite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Phonolite consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Phonolite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Laterite is Rough and Banded and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Laterite vs Phonolite. The hardness of Laterite is 2 and that of Phonolite is 5.5-6. The types of Laterite are Laterite whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Phonolite is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Phonolite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Laterite is heat resistant, pressure resistant whereas Phonolite is heat resistant, impact resistant, wear resistant.
