What else can I help you with?
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Is peridot a igneous rock or is it something else?
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.
What color are peridotites?
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.
What type of rock contains high-density minerals such as olivine?
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.
Which types of igneous rocks are composed of at least 50 percent olivine?
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.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Which mineral is not a typical mineral found in granite?
One mineral that is not typically found in granite is olivine. Granite is primarily composed of quartz, feldspar, and mica, while olivine is more commonly associated with mafic and ultramafic igneous rocks, such as basalt and peridotite. Thus, olivine's presence in granite would be unusual.
Is peridot a igneous rock or is it something else?
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.
What color are peridotites?
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.
Is olivine an igneous rock?
Olivine is not an igneous rock itself; rather, it is a mineral commonly found in igneous rocks. It is a silicate mineral composed of magnesium and iron and is typically found in mafic and ultramafic rocks such as basalt and peridotite. Olivine can crystallize from magma and is often one of the first minerals to form during the cooling of molten rock.
An igneous rock that contains mostly pyroxene and olivine has .?
an ultramafic composition
Which igneous rock out of granite basalt andesite and peridotite has the lowest silica SiO2 content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.
What type of rock contains high-density minerals such as olivine?
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.
What igneous rock may be formed by fractional crystallization of olivine and pyroxene?
ultramafic
Which types of igneous rocks are composed of at least 50 percent olivine?
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.
Where is peridotite found?
Peridotite is a dense, coarse-grained plutonic rock that contains a large amount of olivine. Spinel-bearing peridotites and plagioclase-bearing peridotites are foliated.
What is the density of dunite?
a bout 3.27 (most of the time 3.3 is considered)
