Basalt
Basalt is a common example of a mafic rock. It is dark in color, fine-grained, and rich in minerals like pyroxene and olivine. Basalt is formed from the solidification of magma with low silica content, typically from volcanic activity.
The igneous rock with mostly pyroxenes and olivine is likely a mafic rock, such as basalt or gabbro. These minerals are common in mafic rocks due to their high iron and magnesium content. Mafic rocks are associated with oceanic crust and volcanic activity.
A Mafic rock is a type of igneous rock that is rich in Iron and Magnesium instead of silica. The rocks are also darker in color like Basalt.
Gabbro is a type of mafic phaneritic rock. It is composed mainly of pyroxene, plagioclase feldspar, and often contains minor amounts of amphibole, olivine, or biotite. Gabbro forms from the slow crystallization of mafic magma deep within the Earth's crust.
Monzonite is an intermediate rock.

Composite volcanoes usually do not erupt mafic material. Intermediate material is the most common. The mafic material they do erupt is usually basalt.

No. Granite is an intrusive felsic rock.
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Mafic
Mafic and felsic.
Gabbro is a type of mafic phaneritic rock. It is composed mainly of pyroxene, plagioclase feldspar, and often contains minor amounts of amphibole, olivine, or biotite. Gabbro forms from the slow crystallization of mafic magma deep within the Earth's crust.
Monzonite is an intermediate rock.
No. The terms mafic and felsic apply to igneous rocks. Limestone is a sedimentary/biochemical rock and so cannot be said to be mafic, felsic, or intermediate.
A mafic rock, such as gabbro or basalt, may be formed through fractional crystallization of olivine and pyroxene. Mafic rocks are characterized by their high content of magnesium and iron, which are common components of olivine and pyroxene minerals.
