Mylonite vs Trondhjemite

1 Definition
1.1 Definition
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism
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.

5 Formation
5.1 Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

Mylonite 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 Mylonite and Trondhjemite Reserves. Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. 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 Mylonite vs Trondhjemite information and Mylonite vs Trondhjemite characteristics in the upcoming sections.

Mylonite 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. Mylonite vs Trondhjemite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Trondhjemite. Learn more about Mylonite vs Trondhjemite in the next section.

More about Mylonite and Trondhjemite

Here you can know more about Mylonite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Trondhjemite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts 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 Mylonite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Mylonite vs Trondhjemite. The hardness of Mylonite is 3-4 and that of Trondhjemite is 6-7. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Trondhjemite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite is white while that of Trondhjemite is bluish black. The specific heat capacity of Mylonite is 1.50 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.Mylonite is heat resistant, impact resistant, pressure resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
