Definition

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.

Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

Formation

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

The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Trondhjemite vs Appinite 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 Trondhjemite and Appinite Reserves. 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.. Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished. 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.

More about Trondhjemite and Appinite

Here you can know more about Trondhjemite and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trondhjemite and Appinite consists of mineral content and compound content. The mineral content of Trondhjemite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Trondhjemite vs Appinite, the texture, color and appearance plays an important role in determining the type of rock. Trondhjemite is available in black, brown, light to dark grey, white colors whereas, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Trondhjemite is Banded and Foilated and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Trondhjemite vs Appinite. The hardness of Trondhjemite is 6-7 and that of Appinite is 5-6. The types of Trondhjemite are Intermediate intrusive rock whereas types of Appinite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Trondhjemite is bluish black while that of Appinite is white. The specific heat capacity of Trondhjemite is 0.92 kJ/Kg K and that of Appinite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Trondhjemite is heat resistant, pressure resistant, wear resistant whereas Appinite is heat resistant, impact resistant.
