5.1 Formation

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

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

Evaporite vs Pumice 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 Evaporite and Pumice Reserves. A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. 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 Evaporite vs Pumice information and Evaporite vs Pumice characteristics in the upcoming sections.

More about Evaporite and Pumice

Here you can know more about Evaporite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Pumice consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in colourless, green, grey, silver, white colors whereas, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Pumice is Vesicular. Properties of rock is another aspect for Evaporite vs Pumice. The hardness of Evaporite is 2-3 and that of Pumice is 6. The types of Evaporite are Not Available whereas types of Pumice are Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite is white while that of Pumice is white, greenish white or grey. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
