Applied gabbro
Basal igneous rock
Dark gray to black and dark olive green in some layers (due to the presence of olivine or pyroxene). The color gradient pattern results from the layered stacking of minerals.
فانيريتك Phaneritic
Plagioclase, pyroxene
Silica content (SiO₂): 45-52%
It is classified as a basic rock.
It is formed deep in the Earth's crust.
It often forms in large magma chambers through:
Crystal Settling
or Magmatic Layering
Repeating bands of varying colors depending on the mineral concentration and a strong, solid structure, reveal a long crystallization history.
1- An important source of some economic raw materials, such as chromite.
2- Geological research to understand the development of magma chambers.
Arabian Shield rocks, Saudi Arabia, Al Bahah region, Ablah, Wadi Rania.
