Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

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.

Latite vs Nephelinite 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 Nephelinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Nephelinite. Learn more about Latite vs Nephelinite in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Nephelinite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Latite and Nephelinite, 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 Nephelinite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Latite and Nephelinite
Here you can know more about Latite and Nephelinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Nephelinite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Nephelinite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas, Nephelinite is available in black, brown, colourless, green, grey, white colors. Appearance of Latite is Rough and that of Nephelinite is Skeletal. Properties of rock is another aspect for Latite vs Nephelinite. The hardness of Latite is 5-5.5 and that of Nephelinite is 6.5. The types of Latite are Rhomb porphyries whereas types of Nephelinite are Peralkaline Nephelinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite and Nephelinite is white. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Nephelinite is 0.88 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 Nephelinite is heat resistant.
