Difference Between Pyroxene And Amphibole

Spread the love

Pyroxene and amphibole are both types of inorganic compounds that contain oxygen. They are similar in many ways, but there are also some key differences between them. For example, pyroxene is a silicate while amphibole is a nonsilicate. Pyroxene also has a higher melting point than amphibole. Additionally, amphiboles typically have more double bonds than pyroxenes.

What is Pyroxene ?

Pyroxene is a rock-forming mineral found in many igneous and metamorphic rocks. It is chemically similar to amphibole, with the exception of the +4 oxidation state of iron. Pyroxenes are typically iron-rich and vary in color from yellow to brown or black. The name pyroxene comes from the Ancient Greek word for fire, pyr.

Pyroxene minerals make up a large percentage of the Earth’s crust, and can be found on all continents. They are an important component of basalt, gabbro, and norite. Pyroxenes are also found in many meteorites, including those that contain diamonds.

What is Amphibole?

Amphibole is a term used to describe a group of inorganic silicate minerals. Amphiboles are found in all three major rock types: igneous, sedimentary, and metamorphic. The word amphibole comes from the Greek amphibolos, which means “ambiguous.” This refers to the fact that amphiboles can be difficult to identify because they can occur in a variety of colors and have a wide range of compositions.

There are two main subgroups of amphiboles: the true amphiboles and the pseudo-amphiboles. The true amphiboles include minerals such as anthophyllite, cummingtonite, grunerite, hornblende, and tremolite. The pseudo-amphiboles include minerals such as actinolite, pargasite, and riebeckite.

Main differences between Pyroxene and Amphibole

Pyroxene and amphibole are two groups of rock-forming inosilicate minerals. They are both silicate minerals, meaning that they have silicon and oxygen in their chemical structure. The main difference between pyroxene and amphibole is that pyroxenes are single-chain inosilicates while amphiboles are double-chain inosilicates.

Pyroxenes are made up of chains of SiO4 tetrahedra, while amphiboles are made up of chains ofSiO4 tetrahedra and HO4 octahedra. Pyroxenes can be found in igneous, metamorphic, and sedimentary rocks, while amphiboles are only found in metamorphic and igneous rocks. Amphiboles have a wider range of colors than pyroxenes, due to the presence of metal ions in their structure.

Similar Frequently Asked Questions (FAQ)

What are the most common types of amphiboles?

There are two types of amphiboles: pyroxene and amphibole. Pyroxenes are the most common type of amphibole, and they are found in both metamorphic and igneous rocks. Amphiboles are less common, and they are found in metamorphic rocks only.

The main difference between pyroxene and amphibole is their chemical composition. Pyroxenes contain iron and magnesium, while amphiboles contain calcium, sodium, and potassium. Amphiboles also have a higher percentage of water than pyroxenes.

Both pyroxene and amphibole minerals have a variety of uses. Pyroxenes are used in the manufacture of glass and ceramics, while amphiboles are used as gemstones and in jewelry making.

In conclusion,it is important to understand the difference between pyroxene and amphibole. Pyroxene is a rock-forming mineral that is found in igneous and metamorphic rocks. Amphibole is a group of minerals that includes hornblende, tremolite, and actinolite. Amphiboles are found in metamorphic and igneous rocks.
