Definition
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

Anorthosite vs Marble 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 Marble characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Marble. Learn more about Anorthosite vs Marble in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Anorthosite and Marble, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Marble include As dimension stone.
More about Anorthosite and Marble
Here you can know more about Anorthosite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Marble consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Marble is Veined and Shiny. Properties of rock is another aspect for Anorthosite vs Marble. The hardness of Anorthosite is 5-6 and that of Marble is 3-4. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Marble is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
