Pumice vs Nephelinite

1 Definition
1.1 Definition
Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals
Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).

5 Formation
5.1 Formation
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.
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.

Pumice vs Nephelinite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Pumice and Nephelinite Reserves. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Pumice vs Nephelinite information and Pumice vs Nephelinite characteristics in the upcoming sections.

Pumice vs Nephelinite 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. Pumice vs Nephelinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pumice and Properties of Nephelinite. Learn more about Pumice vs Nephelinite in the next section. The interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Nephelinite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Pumice and Nephelinite, they have various applications in construction industry. The uses of Pumice in construction industry include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks and that of Nephelinite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.

More about Pumice and Nephelinite

Here you can know more about Pumice and Nephelinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Nephelinite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Nephelinite, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors whereas, Nephelinite is available in black, brown, colourless, green, grey, white colors. Appearance of Pumice is Vesicular and that of Nephelinite is Skeletal. Properties of rock is another aspect for Pumice vs Nephelinite. The hardness of Pumice is 6 and that of Nephelinite is 6.5. The types of Pumice are Scoria 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 Pumice and Nephelinite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 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.Pumice is impact resistant, pressure resistant whereas Nephelinite is heat resistant.
