Formation

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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 Evaporite and Nephelinite

Here you can know more about Evaporite and Nephelinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Nephelinite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite 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 Evaporite vs Nephelinite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in green, grey, silver, white colors whereas, Nephelinite is available in black, brown, green, grey, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Nephelinite is Skeletal. Properties of rock is another aspect for Evaporite vs Nephelinite. The hardness of Evaporite is 2-3 and that of Nephelinite is 6.5. The types of Evaporite are Sedimentary rock 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 Evaporite and Nephelinite is white. The specific heat capacity of Evaporite 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.Evaporite is heat resistant, pressure resistant whereas Nephelinite is heat resistant.
