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.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Anorthosite vs Diabase Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Anorthosite and Diabase Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Anorthosite vs Diabase information and Anorthosite vs Diabase characteristics in the upcoming sections.

Anorthosite vs Diabase 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 Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Diabase. Learn more about Anorthosite vs Diabase in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Anorthosite and Diabase, 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 Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Anorthosite and Diabase

Here you can know more about Anorthosite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Diabase consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Diabase, 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, Diabase is available in dark grey to black colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Diabase is Vesicular. Properties of rock is another aspect for Anorthosite vs Diabase. The hardness of Anorthosite is 5-6 and that of Diabase is 7. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Diabase are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite is white while that of Diabase is black. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Diabase is Not Available. 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
