· Azurite is a stunning mineral known for its deep blue color, adding a splash of brilliance to the rocks found in Alabama. It’s made of copper, carbon, and oxygen, and usually forms in places where copper-rich rocks are exposed to air and water. This process, called weathering, changes the copper into azurite over time.

To identify a mineral, first observe its physical characteristics like hardness, color, streak, luster, cleavage, and specific gravity. Write these traits down, then compare the mineral’s traits to those of known mineral types. Additionally, you can use identification resources like books and flow charts.

Rocks are aggregates of one or more minerals, mineraloids, and organic components. Rocks may form when minerals grow ( crystallize) together, forming a crystalline rock, such as the granite shown above. They also can form when loose grains are cemented together, forming a clastic rock, such as sandstone. Crystalline rocks may form from a magma
