Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
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 Marble and Nephelinite
Here you can know more about Marble and Nephelinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marble and Nephelinite consists of mineral content and compound content. The mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz 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 Marble vs Nephelinite, the texture, color and appearance plays an important role in determining the type of rock. Marble is available in black, blue, brown, grey, pink, white colors whereas, Nephelinite is available in black, brown, colourless, green, grey, white colors. Appearance of Marble is Veined and Shiny and that of Nephelinite is Skeletal. Properties of rock is another aspect for Marble vs Nephelinite. The hardness of Marble is 3-4 and that of Nephelinite is 6.5. The types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble 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 Marble and Nephelinite is white. The specific heat capacity of Marble is 0.88 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.Marble is heat resistant whereas Nephelinite is heat resistant.
