Igneous Rocks
Igneous rock is shaped via the cooling and solidification of magma or lava. The magma may be derived from partial melts of existing rocks in both a planet’s mantle or crust.
Norite
Norite is a type of igneous rock that is primarily composed of the mineral orthopyroxene, along with plagioclase feldspar. It is a mafic rock,...

Monzonite
Monzonite is a type of igneous rock that falls within the category of intrusive or plutonic rocks. It is primarily composed of minerals such...
Granodiorite
Granodiorite is a phaneritic-textured intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. According to the QAPF diagram, granodiorite has a greater than 20% quartz by volume, and between 65% to 90% of the feldspar is plagioclase. A greater amount of plagioclase would designate the rock as tonalite.
Anorthosite
Anorthosite is a type of igneous rock that is primarily composed of a mineral called plagioclase feldspar. It is known for its distinctive light-colored...
