Formation
Norite 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 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.

Norite 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. Norite vs Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Norite and Properties of Latite. Learn more about Norite vs Latite in the next section. The interior uses of Norite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Norite and Latite, they have various applications in construction industry. The uses of Norite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate 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 Norite and Latite
Here you can know more about Norite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Latite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, 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 Norite vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Norite is Veined and Shiny and that of Latite is Rough. Properties of rock is another aspect for Norite vs Latite. The hardness of Norite is 7 and that of Latite is 5-5.5. The types of Norite are Ultramafic intrusive rock 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 Norite is black while that of Latite is white. The specific heat capacity of Norite is 0.52 kJ/Kg K 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.Norite is impact resistant, pressure resistant, wear resistant whereas Latite is heat resistant, pressure resistant.
