Definition
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase

Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
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.

More about Adamellite and Anorthosite
Here you can know more about Adamellite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adamellite and Anorthosite consists of mineral content and compound content. The mineral content of Adamellite includes Apatite, Biotite, Chlorite, Orthoclase, Perthite, Plagioclase, Quartz, Titanite, Zircon and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Adamellite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Adamellite is available in black, grey, orange, pink, white colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Adamellite is Veined or Pebbled and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Adamellite vs Anorthosite. The hardness of Adamellite is 6-7 and that of Anorthosite is 5-6. The types of Adamellite are Not Available whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adamellite and Anorthosite is white. The specific heat capacity of Adamellite is 0.79 kJ/Kg K and that of Anorthosite 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.Adamellite is heat resistant, wear resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
