Formation
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
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.

Jaspillite 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. Jaspillite vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jaspillite and Properties of Anorthosite. Learn more about Jaspillite vs Anorthosite in the next section. The interior uses of Jaspillite include Decorative aggregates and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Jaspillite and Anorthosite, they have various applications in construction industry. The uses of Jaspillite 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 Jaspillite and Anorthosite
Here you can know more about Jaspillite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Anorthosite consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Jaspillite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Jaspillite is Banded and Glassy and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Jaspillite vs Anorthosite. The hardness of Jaspillite is 3 and that of Anorthosite is 5-6. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type 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 Jaspillite and Anorthosite is white. The specific heat capacity of Jaspillite is 3.20 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.Jaspillite is heat resistant, impact resistant, wear resistant whereas Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
