Serpentinite vs Trondhjemite

Definition

Definition

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'.
Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.

Formation

Formation

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.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

Serpentinite vs Trondhjemite 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 Serpentinite and Trondhjemite Reserves. 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'.. Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.. 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 Serpentinite vs Trondhjemite information and Serpentinite vs Trondhjemite characteristics in the upcoming sections.

Serpentinite vs Trondhjemite 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. Serpentinite vs Trondhjemite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Trondhjemite. Learn more about Serpentinite vs Trondhjemite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Trondhjemite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration.

More about Serpentinite and Trondhjemite

Here you can know more about Serpentinite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Trondhjemite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Trondhjemite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Serpentinite is Rough and Dull and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Serpentinite vs Trondhjemite. The hardness of Serpentinite is 3-5 and that of Trondhjemite is 6-7. The types of Serpentinite are Jadeitite whereas types of Trondhjemite are Intermediate intrusive rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite is white, greenish white or grey while that of Trondhjemite is bluish black. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Trondhjemite 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.Serpentinite is heat resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
