Definition

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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 Serpentinite and Nephelinite

Here you can know more about Serpentinite and Nephelinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Nephelinite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Nephelinite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Nephelinite is available in black, brown, green, grey, white colors. Appearance of Serpentinite is Rough and Dull and that of Nephelinite is Skeletal. Properties of rock is another aspect for Serpentinite vs Nephelinite. The hardness of Serpentinite is 3-5 and that of Nephelinite is 6.5. The types of Serpentinite are Jadeitite 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 Serpentinite and Nephelinite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 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.Serpentinite is heat resistant whereas Nephelinite is heat resistant.
