Augite is a common rock-forming mineral that belongs to the pyroxene group. It is typically found in igneous rocks such as basalt and gabbro, as well as in some metamorphic rocks. Augite is a dark-colored mineral that can range from black to greenish-black in color.
One of the key characteristics of augite is its distinct cleavage, which is the way the mineral breaks along flat planes. This mineral has two cleavage directions at around 87 and 93 degrees. This property helps geologists identify and distinguish augite from other minerals.
Composition and Structure
Augite is composed of calcium, magnesium, iron, aluminum, silicon, and oxygen. It has a monoclinic crystal structure, meaning its crystals have three unequal axes with one oblique intersection point. This crystal structure gives augite its unique properties and appearance.
Within its crystal structure, augite forms short prismatic or tabular crystals. These crystals often exhibit striations on their surfaces, which are fine linear grooves that can help in identifying the mineral.
Uses and Applications
While augite itself does not have significant commercial uses, its presence in rocks and minerals provides valuable information to geologists about the formation processes of certain rock types. By studying the occurrence of augite in different geological settings, scientists can better understand the history and evolution of Earth's crust.
Overall, augite plays a crucial role in the field of geology as a marker mineral for specific rock types and geological events. Its unique properties and composition make it a fascinating mineral for study and analysis in various scientific disciplines.
