Formation

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.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

Pumice vs Carbonatite 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 Carbonatite Reserves. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals. 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 Carbonatite information and Pumice vs Carbonatite characteristics in the upcoming sections.

Pumice vs Carbonatite 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 Carbonatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pumice and Properties of Carbonatite. Learn more about Pumice vs Carbonatite in the next section. The interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Carbonatite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Pumice and Carbonatite, 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 Carbonatite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Pumice and Carbonatite

Here you can know more about Pumice and Carbonatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Carbonatite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Carbonatite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Carbonatite, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors whereas, Carbonatite is available in black, brown, green, grey, pink, white colors. Appearance of Pumice is Vesicular and that of Carbonatite is Dull, Banded and Foilated. Properties of rock is another aspect for Pumice vs Carbonatite. The hardness of Pumice is 6 and that of Carbonatite is 3. The types of Pumice are Scoria whereas types of Carbonatite are Carbonatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pumice and Carbonatite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 kJ/Kg K and that of Carbonatite is 0.51 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 Carbonatite is heat resistant, pressure resistant, water resistant.
