Definition

Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation

Formation

Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Arkose vs Serpentinite 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 Arkose and Serpentinite Reserves. Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. 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 Arkose vs Serpentinite information and Arkose vs Serpentinite characteristics in the upcoming sections.

Arkose vs Serpentinite 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. Arkose vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Serpentinite. Learn more about Arkose vs Serpentinite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Arkose and Serpentinite, they have various applications in construction industry. The uses of Arkose in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Arkose and Serpentinite

Here you can know more about Arkose and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Serpentinite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Arkose vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Arkose is Rough and Dull and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Arkose vs Serpentinite. The hardness of Arkose is 6-7 and that of Serpentinite is 3-5. The types of Arkose are Arkose whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Arkose is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Arkose is 0.78 kJ/Kg K and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Arkose is heat resistant, impact resistant, pressure resistant whereas Serpentinite is heat resistant.
