Anorthosite vs Trondhjemite

Definition

Definition

Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase
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

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

Anorthosite 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 Anorthosite and Trondhjemite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. 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 Anorthosite vs Trondhjemite information and Anorthosite vs Trondhjemite characteristics in the upcoming sections.

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

More about Anorthosite and Trondhjemite

Here you can know more about Anorthosite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Trondhjemite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene 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 Igneous Rocks. When we have to compare Anorthosite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Anorthosite vs Trondhjemite. The hardness of Anorthosite is 5-6 and that of Trondhjemite is 6-7. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite 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 Anorthosite is white while that of Trondhjemite is bluish black. The specific heat capacity of Anorthosite is 0.84 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
