5 Formation

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.

Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.

Anorthosite vs Taconite 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 Taconite Reserves. Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase. Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica. 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 Taconite information and Anorthosite vs Taconite characteristics in the upcoming sections.
