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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

Anorthosite vs Diorite 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 Diorite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene. 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 Diorite information and Anorthosite vs Diorite characteristics in the upcoming sections.

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

More about Anorthosite and Diorite
