Basalt contains minerals such as plagioclase feldspar, pyroxene, and olivine. Gabbro also contains plagioclase feldspar and pyroxene, but generally has a coarser texture due to slower cooling rates underground.
Gabbro is a coarse-grained, intrusive igneous rock composed mainly of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine. Basalt, on the other hand, is a fine-grained, extrusive igneous rock composed mainly of plagioclase feldspar and pyroxene. Basalt is typically found on the Earth's surface, while gabbro is usually found beneath the surface as intrusive rock formations.
Olivine: a common silicate mineral found in igneous rocks. Augite: a pyroxene mineral commonly found in basalt and gabbro. Biotite: a dark-colored mica mineral often found in granite and other igneous rocks.
The dark-colored igneous rock rich in iron and magnesium is called basalt. Basalt is a fine-grained rock that is commonly found in volcanic areas and oceanic crust. It is characterized by its dark color due to the presence of minerals like pyroxene and olivine.
The dark-colored mineral in coarse-grained igneous rocks is likely to be biotite or hornblende. These minerals are commonly found in rocks like diorite, gabbro, and basalt.

Um....Gold?NOPE!Its Basalt And Gabbro
The dark-colored mineral in coarse-grained igneous rocks is likely to be biotite or hornblende. These minerals are commonly found in rocks like diorite, gabbro, and basalt.
Plagioclase feldspar is a common mineral in igneous rocks, while quartz is a mineral often found in a variety of rocks. Olivine is a green mineral commonly found in mafic igneous rocks. When all three minerals are present in a rock, it typically indicates a mafic igneous rock such as basalt or gabbro.
Vesicular basalt or pegmatite veins.
Basalt is a dark-colored igneous rock that ranges from black to dark green in color. It is commonly found in volcanic areas and is rich in iron and magnesium minerals.
An example of an extrusive igneous rock is basalt. Basalt forms from the rapid cooling of lava on the Earth's surface and is commonly found in volcanic areas. It has a fine-grained texture due to its quick cooling process.
Basalt
The igneous rock with mostly plagioclase feldspar and about 30 percent dark silicate minerals is likely a basalt. Basalt is a fine-grained extrusive rock that is commonly found in oceanic crust and volcanic islands. The dark silicate minerals in basalt are typically pyroxene and olivine.
