Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.

Appinite vs Latite 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. Appinite vs Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Appinite and Properties of Latite. Learn more about Appinite vs Latite in the next section. The interior uses of Appinite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Appinite and Latite, they have various applications in construction industry. The uses of Appinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Latite 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.
More about Appinite and Latite
Here you can know more about Appinite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Latite consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Appinite vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Latite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Appinite is Dull, Banded and Foilated and that of Latite is Rough. Properties of rock is another aspect for Appinite vs Latite. The hardness of Appinite is 5-6 and that of Latite is 5-5.5. The types of Appinite are Not Available whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Appinite and Latite is white. The specific heat capacity of Appinite is Not Available and that of Latite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Appinite is heat resistant, impact resistant whereas Latite is heat resistant, pressure resistant.
