Formation
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Latite vs Comendite 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. Latite vs Comendite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Comendite. Learn more about Latite vs Comendite in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Comendite include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Latite and Comendite, they have various applications in construction industry. The uses of Latite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Comendite include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Raw material for the manufacture of mortar.
More about Latite and Comendite
Here you can know more about Latite and Comendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Comendite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Comendite includes Albite, Amphibole, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Comendite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, green, grey, pink, white colors whereas, Comendite is available in blue, bluish - grey colors. Appearance of Latite is Rough and that of Comendite is Foliated. Properties of rock is another aspect for Latite vs Comendite. The hardness of Latite is 5-5.5 and that of Comendite is 6-7. The types of Latite are Rhomb porphyries whereas types of Comendite are Rhyolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite is white while that of Comendite is bluish black. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Comendite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Latite is heat resistant, pressure resistant whereas Comendite is heat resistant, impact resistant.
