What igneous rock contains mostly pyroxene and olivine?
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
What are 3 examples of ferromagnesian minerals?
Olivine: a common silicate mineral found in igneous rocks. Augite: a pyroxene mineral commonly found in basalt and gabbro. Biotite: a dark-colored mica mineral often found in granite and other igneous rocks.
Which minerals are found in the igneous rocks gabbro and basalt?
Gabbro and basalt are both mafic igneous rocks and contain minerals such as pyroxene, plagioclase feldspar, and olivine. Gabbro typically has a coarser grain size compared to basalt, which has a fine-grained texture due to its rapid cooling at the Earth's surface.
Is peridotite intrusive or extrusive?
Peridotite is an intrusive igneous rock, meaning it forms below the Earth's surface from the slow cooling of magma. It is primarily composed of olivine and pyroxene minerals, and is commonly found in the upper mantle.
Peridotite is composed almost entirely of dark silicate minerals.?
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.

Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.

Is pyroxene a mineral?
A pyroxene is any of a group of crystalline silicate mineral common in igneous and metamorphic rocks.
Is peridotite intrusive or extrusive?
Peridotite is an intrusive igneous rock, meaning it forms below the Earth's surface from the slow cooling of magma. It is primarily composed of olivine and pyroxene minerals, and is commonly found in the upper mantle.
Where is pyroxene found?
Pyroxene minerals are commonly found in igneous and metamorphic rocks. They can also be found in some high-temperature and low-pressure metamorphic rocks, as well as in some meteorites.

What are three main rocks found on this planet?
The three main rocks found on this planet are sedimentary, igneous, and metamorphic.
What are 2 elements that can be found in both olivine and pyroxene?
Silicates.
Are olivine and pyroxene most likely to be found in felsic rock?
No, olivine and pyroxene are more commonly found in mafic rocks due to their high iron and magnesium content. Felsic rocks, on the other hand, typically contain minerals like quartz, feldspar, and mica, which have lower iron and magnesium content.
Which minerals are found in basalt and gabbro?
Basalt contains minerals such as plagioclase feldspar, pyroxene, and olivine. Gabbro also contains plagioclase feldspar and pyroxene, but generally has a coarser texture due to slower cooling rates underground.
