5 Formation

5.1 Formation

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

Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

Evaporite vs Dacite 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 Dacite Reserves. A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. 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 Dacite information and Evaporite vs Dacite characteristics in the upcoming sections.

More about Evaporite and Dacite

Here you can know more about Evaporite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Dacite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all . When we have to compare Evaporite vs Dacite, 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, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Dacite is Vesicular. Properties of rock is another aspect for Evaporite vs Dacite. The hardness of Evaporite is 2-3 and that of Dacite is 2-2.25. The types of Evaporite are Not Available whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Dacite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Dacite is 0.92 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 Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
