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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Anorthosite vs Andesite 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 Andesite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. 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 Andesite information and Anorthosite vs Andesite characteristics in the upcoming sections.

Anorthosite vs Andesite 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 Andesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Andesite. Learn more about Anorthosite vs Andesite in the next section.
