Formation
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
  
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.

Latite vs Anorthosite 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. Latite vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Anorthosite. Learn more about Latite vs Anorthosite in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Latite and Anorthosite, they have various applications in construction industry. The uses of Latite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.
More about Latite and Anorthosite
Here you can know more about Latite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Anorthosite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene 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 Latite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Latite is Rough and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Latite vs Anorthosite. The hardness of Latite is 5-5.5 and that of Anorthosite is 5-6. The types of Latite are Rhomb porphyries 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 Latite and Anorthosite is white. The specific heat capacity of Latite is 0.92 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.Latite is heat resistant, pressure resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
