Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

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.
Nephelinite 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.

More about Turbidite and Nephelinite
Here you can know more about Turbidite and Nephelinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Nephelinite consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Nephelinite, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Nephelinite is available in black, brown, colourless, green, grey, white colors. Appearance of Turbidite is Dull and Banded and that of Nephelinite is Skeletal. Properties of rock is another aspect for Turbidite vs Nephelinite. The hardness of Turbidite is 3 and that of Nephelinite is 6.5. The types of Turbidite are Not Available 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 Turbidite and Nephelinite is white, greenish white or grey. The specific heat capacity of Turbidite 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.Turbidite is heat resistant whereas Nephelinite is heat resistant.
