Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

Formation
Syenites 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.

Syenite 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. Syenite vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Syenite and Properties of Laterite. Learn more about Syenite vs Laterite in the next section. The interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Syenite and Laterite, they have various applications in construction industry. The uses of Syenite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Syenite and Laterite
Here you can know more about Syenite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Laterite consists of mineral content and compound content. The mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Syenite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas, Laterite is available in brown, buff, red colors. Appearance of Syenite is Banded and Foilated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Syenite vs Laterite. The hardness of Syenite is 5.5-6 and that of Laterite is 2. The types of Syenite are Shonkinite 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 Syenite and Laterite is white. The specific heat capacity of Syenite is 0.92 kJ/Kg K 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.Syenite is heat resistant, impact resistant, wear resistant whereas Laterite is heat resistant, pressure resistant.
