5 Formation
5.1 Formation
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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Dacite vs Suevite 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 Dacite and Suevite Reserves. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.. 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 Dacite vs Suevite information and Dacite vs Suevite characteristics in the upcoming sections.

Dacite vs Suevite 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. Dacite vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dacite and Properties of Suevite. Learn more about Dacite vs Suevite in the next section. The interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Dacite and Suevite, they have various applications in construction industry. The uses of Dacite in construction industry include As dimension stone, Construction aggregate, For road aggregate, Landscaping and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Dacite and Suevite

Here you can know more about Dacite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Suevite consists of mineral content and compound content. The mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Dacite is Vesicular and that of Suevite is Banded. Properties of rock is another aspect for Dacite vs Suevite. The hardness of Dacite is 2-2.25 and that of Suevite is 5.5. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite is white while that of Suevite is light to dark brown. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Suevite 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.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Suevite is heat resistant.
