What do people use augite for?
Augite is a mineral of interest to geologists, and collectors. While it has little to no industrial value, the presence and development of augite may help tell scientists and geologists about Earth’s history in certain regions.
Where is augite most commonly found?
igneous rocks
Augite is commonly found in igneous rocks such as gabbros, basalts and andesites, and high grade metamorphic rocks (granulites).
How do you use augite?
A stone that temporarily radiates light when it comes into contact with air.It is prized as a one-of-a-kind jewel, but with no use in crafting, it is mostly employed simply as a guidepost….

How do you identify augite?
Augite is usually green, black, or brown in color with a translucent to opaque diaphaneity. It usually exhibits two distinct cleavage directions that intersect at slightly less than 90 degrees. A hand lens is often needed to properly observe the cleavage, especially in fine-grained rocks.
Is diopside a CPX?
The most significant clinopyroxene end member is diopside, CaMgSi2O6. Its Fe equivalent, CaFeSi2O6 is termed hedenbergite. Near end-member diopside is found in some marbles.
Is augite metallic or non metallic?

How do you identify Augite in thin section?
Augite is a clinopyroxene. Clinopyroxenes and orthopyroxenes are easily distinguished in thin section by their extinction angles: clinopyroxenes have inclined extinction, and orthopyroxenes have parallel extinction.
Where can augite be found in a rock?
Augite is a rock-forming mineral of the pyroxene group commonly found within igneous and metamorphic rocks. Because its chemical structure is highly variable, augite might be considered by some to be its own group of minerals rather than an individual mineral. It is also known for its remarkable luster (shine off of a reflective surface). Type.
How can you tell the properties of augite?
Augite is often brittle, breaking into splintery fragments on the streak plate. These can be observed with a hand lens. Rubbing the debris with a finger produces a gritty feel with a fine white powder beneath. Vitreous on cleavage and crystal faces. Dull on other surfaces. Usually translucent to opaque. Rarely transparent.
Why is augite considered a group of minerals?
Because its chemical structure is highly variable, augite might be considered by some to be its own group of minerals rather than an individual mineral. It is also known for its remarkable luster (shine off of a reflective surface). Augite is a mineral of interest to geologists, and collectors.
How did the name augite get its name?
The most common pyroxene, augite is named after the Greek word augites, which means “brightness”—a reference to its occasional shiny appearance. Most augite has a dull, dark green, brown, or black finish.
