Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
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.

Turbidite vs Norite 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. Turbidite vs Norite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Norite. Learn more about Turbidite vs Norite in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Norite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Turbidite and Norite, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Norite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Turbidite and Norite
Here you can know more about Turbidite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Norite consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, green, grey, pink colors whereas, Norite is available in dark grey to black colors. Appearance of Turbidite is Dull and Banded and that of Norite is Veined and Shiny. Properties of rock is another aspect for Turbidite vs Norite. The hardness of Turbidite is 3 and that of Norite is 7. The types of Turbidite are Sedimentary rock whereas types of Norite are Ultramafic intrusive rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Turbidite is white, greenish white or grey while that of Norite is black. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Norite is 0.52 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Turbidite is heat resistant whereas Norite is impact resistant, pressure resistant, wear resistant.
