5.1 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.

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

More about Anorthosite and Mylonite

Here you can know more about Anorthosite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Mylonite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Mylonite, 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, Mylonite is available in black to grey colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Anorthosite vs Mylonite. The hardness of Anorthosite is 5-6 and that of Mylonite is 3-4. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Mylonite is white.
