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.
Silicates.
Pyroxene is a group of minerals.
Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
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.
The igneous rock that is fine-grained and contains a significant amount of pyroxene is basalt. This volcanic rock forms from the rapid cooling of lava at the Earth's surface, resulting in its fine-grained texture. Basalt typically contains minerals like pyroxene and plagioclase feldspar, and it is commonly found in oceanic crust and volcanic islands.
A pyroxene is any of a group of crystalline silicate mineral common in igneous and metamorphic rocks.
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.
Silicates.
No, pyroxene is not an igneous rock; it is a mineral commonly found in igneous rocks. Pyroxene is a group of silicate minerals that are typically characterized by their crystalline structure and high-temperature stability. They are often present in rocks such as basalt and gabbro, contributing to their mineral composition.

No. Pyroxene is a crystalline silicate mineral.
Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
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.

Peridotite is made only of olivine and pyroxene
Olivine and pyroxene are commonly found in igneous rocks that are mafic in composition. These minerals indicate that the rock formed from magma with a higher iron and magnesium content. Mafic igneous rocks tend to be dark in color and have higher densities compared to felsic rocks.
