Trondhjemite vs Granulite


Definition

Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.   
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
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.   
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

Granulite 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 Granulite and Trondhjemite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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 Granulite vs Trondhjemite information and Granulite vs Trondhjemite characteristics in the upcoming sections.

More about Granulite and Trondhjemite

Here you can know more about Granulite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Trondhjemite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz 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 Granulite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Granulite vs Trondhjemite. Hardness of Granulite and Trondhjemite is 6-7. The types of Granulite are Not Available 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 Granulite is white while that of Trondhjemite is bluish black. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
