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.
Basalt, the intrusive version is known as a gabbro
It is rich in magnesium and iron, it is generally dark in color.
They are silcates high in magnesium and iron and are usually dark colored rocks.
Basalt is the most common example of a mafic igneous rock.
Mafic rock is an example of igneous rock which is dominated by olivine, silicates pyroxene, mica, and amphibole. Common mafic rock samples are basalt and gabbro.
Gabbro is a type of mafic, phaneritic igneous rock.
Mafic rock is on average more dense.
These rocks are called mafic igneous rocks, such as basalt. == ==
Mafic magma and rock are higher in density that felsic magma and rock.
Mafic
Mafic is a silicate mineral or rock that is rich in magnesium and iron, and is usually dark in color. It is formed from cooling volcanic lava.
Mafic rock is an example of igneous rock which is dominated by olivine, silicates pyroxene, mica, and amphibole. Common mafic rock samples are basalt and gabbro.
Mafic rock is on average more dense.
Gabbro is a type of mafic, phaneritic igneous rock.
The igneous rock gabbro is black because its composition is mafic. Mafic rocks are low in silica and very high in magnesium and iron. It is the magnesium- and iron-rich content that causes its color to be black.

Basalt, Scoria, Diabase, Basaltic Glass, Gabbro. Obsidian may appear to be mafic due to its dark color but it is actually felsic
Mafic magma and rock are higher in density that felsic magma and rock.
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
The igneous rock peridotite has a very high color index. It is comprised of more than 95% mafic minerals (like olivine), giving it a dark green color.
== Silicon and oxygen.
