Basalt is a volcanic rock that is rich in minerals. It primarily consists of the following minerals: 1. Silicon dioxide (SiO2): This is the most abundant mineral in basalt and gives it its dark gray to black color. 2. Aluminum oxide (Al2O3): This mineral is responsible for basalt's light grayRead more
Basalt is a volcanic rock that is rich in minerals. It primarily consists of the following minerals:
1. Silicon dioxide (SiO2): This is the most abundant mineral in basalt and gives it its dark gray to black color.
2. Aluminum oxide (Al2O3): This mineral is responsible for basalt’s light gray to white color and its vitreous nature.
3. Iron oxide (FeO): This mineral gives basalt its red color and is present in varying amounts depending on the volcanic process.
4. Calcium oxide (CaO): This mineral is also present in varying amounts and contributes to the overall composition of basalt.
5. Magnesium oxide (MgO): This mineral is also found in basalt and plays a role in its composition.
6. Potassium feldspar (K-feldspar): This mineral is present in trace amounts and contributes to basalt’s vitreous nature.
7. Orthoclase (K-feldspar): This mineral is present in trace amounts and contributes to basalt’s vitreous nature.
These minerals are combined in varying proport ions to form basalt, which is a dense, hard, and felsic rock.
