No. Gabbro is mafic-ultramafic. An example of a felsic rock would be a granite or rhyolite.

Are mafic rocks solely intrusive or extrusive?
No. The terms felsic and mafic refers to the relative content of certain minerals in the magma or rock. A mafic rock can be extrusive like basalt, or intrusive like gabbro. Basalt and gabbro can be identical in chemical composition.
What are some examples of intrusive igneous rock?
Granite and gabbro are the two biggies, granite being formed underground by felsic magma, and gabbro being formed underground by mafic magma. Diorite and peridotite are two others.
What type of rock is gabbro?
Gabbro is a type of rock that is dense and dark in color. It is made up of parts of oceanic crust, which is highly compressed.
What are the parent rocks of gabbro?
Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
What does gabbro look like?
Gabbro is a dark rock with visible crystals.
Do Granite and Gabbro have the same chemical composition?
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
How does a Granite rock and a Gabbro rock differ from each other?
The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.

Granite and gabbro are the two biggies, granite being formed underground by felsic magma, and gabbro being formed underground by mafic magma. Diorite and peridotite are two others.
What is lighter gabbro or granite?
Granite is lighter because its composed of felsic minerals while gabbro is made up of dark ferromagnesian minerals.
Is gabbro a moon rock?
YES gabbro is a moon rock
Is a gabbro a mineral?
Gabbro is a rock
What type of rock is gabbro?
Gabbro is a type of rock that is dense and dark in color. It is made up of parts of oceanic crust, which is highly compressed.
Is there a type of rock called Gabbro?
yes there is a rock called gabbro
Is gabbro a phaneritic rock?
Yes, Gabbro is a phaneritic igneous rock.
How does a granite and a gabbro differ?
Granite is a felsic intrusive igneous rock, its light in colour due to the predominance of acidic magma. while Gabbro is a mafic intrusive igneous rock, its dark in colour as a result of high ferromagnetic composition. They are both coarse grained but only differs basically in chemical composition of the magma.
Is Felsic a Intrusive or Extrusive Rock?
It can be either. The term felsic describes the composition of the rock, not where it forms. The general category for intrusive felsic rock is granite while extrusive felsic rock is rhyolite.
