Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Peridot is a gemstone composed of the mineral olivine. Olivine is a common mineral found in igneous rocks such as basalt and peridotite. So, while peridot itself is not an igneous rock, it is closely associated with igneous rocks due to its mineral composition.
Peridotites are typically olive green to brown in color due to the presence of olivine and other minerals like pyroxene and spinel. This coloration gives peridotites their characteristic appearance.
Ultramafic rocks, such as peridotite, are known to contain high-density minerals like olivine. These rocks form deep within the Earth's mantle and often have a coarse-grained texture due to their slow cooling process. Olivine is a common mineral found in ultramafic rocks due to its high melting point and stability under high-pressure conditions.
Peridotite and dunite are examples of igneous rocks that are composed of at least 50 percent olivine. Olivine is a common mineral in these ultramafic rocks, giving them their distinctive color and composition.

an ultramafic composition
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.

Peridotite is a dense, coarse-grained plutonic rock that contains a large amount of olivine. Spinel-bearing peridotites and plagioclase-bearing peridotites are foliated.

Peridotite is ultramafic, composed predominantly of mafic minerals such as olivine and pyroxene. It has low silica content and high magnesium and iron content, making it different from felsic, intermediate, and mafic rocks.
