Intrusive rocks form from molten material (magma) that flows and solidifies underground. These rocks usually have a coarse texture (individual minerals are visible without magnifiion), because the magma cools slowly underground, allowing crystal growth. Common rock types within the intrusive egory are granite and

The Rock GRANITE (Igneous Intrusive Rock) Amethyst Galleries

Granite is possibly the most common igneous rock type known to the general public. Granite, which is named for its "granular" or phaneritic texture, has crystals that tend to be easily seen, although they are generally small. It is a rock that has been used for centuries for many different purposes such as building material.

Igneous Rocks

Igneous rocks are formed by the crystallisation of a magma. The difference between granites and basalts is in silica content and their rates of cooling. A basalt is about 53% SiO2, whereas granite is 73%. Intrusive, slowly cooled inside the crust. (Plutonic rock = formed in the earth). Large crystals. Granite. (Continental crust)

Igneous Rocks: form by crystallizing melted material (magma). They can form either on the surface (extrusive igneous rocks), or deep in the crust (intrusive or plutonic igneous rocks).

These are called intrusive igneous rocks because the magma has intruded into preexiting rock layers. Types of intrusive igneous rocks are granite and basalt .

Granite Wikipedia

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy. The word "granite" comes from the Latin granum, a grain, in reference to the coarsegrained structure of such a holocrystalline rock.

Both are igneous rocks, which means that they cooled from a magma (the earth gets very hot just below the surface, and there is lots of liquid rock available).
