5 Formation

5.1 Formation

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

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.

Peridotite 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 Peridotite and Dacite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite vs Dacite information and Peridotite vs Dacite characteristics in the upcoming sections.

More about Peridotite and Dacite

Here you can know more about Peridotite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Dacite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene 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 Igneous Rocks. When we have to compare Peridotite vs Dacite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Peridotite is Rough and Shiny and that of Dacite is Vesicular. Properties of rock is another aspect for Peridotite vs Dacite. The hardness of Peridotite is 5.5-6 and that of Dacite is 2-2.25. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite 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 Peridotite and Dacite is white. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
