Examples of mafic intrusive igneous rocks include gabbro, diabase, and dolerite. These rocks are typically dark in color and are composed predominantly of minerals such as pyroxene and plagioclase feldspar. Mafic rocks form from magma that is rich in iron and magnesium, with low silica content.

What type of rock can be intrusive and extrusive?
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
How are igneous rocks?
Igneous rocks are generally classified first on the basis of their formation (and therefore their texture) as intrusive or extrusive. Intrusive rocks are solidified from magma under the surface resulting in a visible crystalline texture, and extrusive igneous rocks are solidified from lava at or near the surface, resulting in a small or nearly invisible crystalline texture. Igneous rock can additionally be classified by general chemistry composition as felsic, intermediate, mafic, and ultramafic. Felsic rocks are higher in silica and aluminum. Mafic rocks are higher in magnesium and iron.
What type of igneous rocks are there?
There are two main types of igneous rocks: intrusive (plutonic) rocks which form beneath the Earth's surface through slow cooling of magma, and extrusive (volcanic) rocks which form on or above the Earth's surface through rapid cooling of lava. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
How are igneous rocks classified acording to their..?
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.

Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
Which igneous rocks form below earth's surface?
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
