The extrusive equivalent of peridotite is basalt. Peridotite is a coarse-grained, intrusive igneous rock composed primarily of olivine and pyroxene minerals, while basalt is a fine-grained, extrusive igneous rock composed mainly of plagioclase, pyroxene, and olivine minerals.
The color of an igneous rock is mainly determined by the minerals present in the rock. Different minerals exhibit different colors, such as feldspar being pink or white, while olivine is green. Additionally, the texture and size of mineral grains can also affect the overall color of the rock.
Igneous rocks that are medium colored and have no silica are called mafic rocks. They are mainly composed of magnesium and iron.
No, cinnabar is not an igneous rock. It is a mineral mainly composed of mercury sulfide. It is typically found in hydrothermal veins and is associated with volcanic activity, but it is not classified as an igneous rock.

Igneous rocks are composed mainly of silicate minerals. Granite is mostly quartz, feldspar and mica. Basalt is mainly feldspar, pyroxine and amphibole. Diorite can be a mixture of all of these minerals. Peridotite is mainly olivine (peridot) and pyroxine.
This intrusive igneous rock could be a gabbro. Gabbros are composed mainly of pyroxene and plagioclase feldspar, with lesser amounts of olivine and amphibole. This composition suggests a mafic rock with dark minerals dominating.
Gabbro.
Peridotite is a coarse-grained, dense igneous rock composed mainly of olivine and pyroxene minerals. It is typically green in color due to the high concentration of olivine. Peridotite is commonly found in the Earth's upper mantle and is important in the formation of oceanic lithosphere.
The extrusive equivalent of peridotite is basalt. Peridotite is a coarse-grained, intrusive igneous rock composed primarily of olivine and pyroxene minerals, while basalt is a fine-grained, extrusive igneous rock composed mainly of plagioclase, pyroxene, and olivine minerals.
Gabbro is a rock composed mainly of ferromagnesian minerals like pyroxene and olivine. It is a coarse-grained equivalent of basalt.
Gabbro is a nonfoliated rock, meaning it does not have a layered structure like foliated rocks such as slate or schist. Gabbro is a coarse-grained, intrusive igneous rock composed mainly of pyroxene, plagioclase feldspar, and sometimes olivine.
Olivene is a mineral, not a rock. It can be found in both intrusive and extrusive igneous rocks. The appearance of olivene is mainly controlled by the composition of the magma
The color of an igneous rock is mainly determined by the minerals present in the rock. Different minerals exhibit different colors, such as feldspar being pink or white, while olivine is green. Additionally, the texture and size of mineral grains can also affect the overall color of the rock.
Gabbro is a coarse-grained, intrusive igneous rock composed mainly of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine. Basalt, on the other hand, is a fine-grained, extrusive igneous rock composed mainly of plagioclase feldspar and pyroxene. Basalt is typically found on the Earth's surface, while gabbro is usually found beneath the surface as intrusive rock formations.
Gabbro is a type of intrusive igneous rock that forms beneath Earth's surface from the slow cooling of magma. It is composed mainly of pyroxene, plagioclase feldspar, and minor amounts of olivine and amphibole. Its coarse-grained texture is a result of the slow cooling process.
