It is called a dyke or dike, and could also be referred to as a discordant igneous intrusion.

How is an xenolith rock formed?
A xenolith is a large piece of country rock that has been broken off and/or surrounded by an igneous intrusion. As the magma intrudes the country rock it may completely surround large pieces. These pieces are then called xenoliths.
What is a xenolith and how is it made?
A xenolith is a large piece of country rock that has been broken off and/or surrounded by an igneous intrusion. As the magma intrudes the country rock it may completely surround large pieces. These pieces are then called xenoliths.
How does igneous intrusion end up as a hill?
Basically, igneous intrusion involves the solidifying of magma when it cools in the crust of the Earth. When magma rises through the crust, it intrudes into the existing sedimentary rock layers and forms a hill. The surounding rock may be more prone to erosion and wear away leaving the intrusion jutting above the (eroded) surroundings.
How does magma affect the rocks into which in intrudes?
Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.

Why is magma intrusive?
Magma is molten rock that comes from a layer miles beneath the Eart's crust. When underground pressures force magma upward, it "intrudes" into fissures within the solid rock, separating the layers of rock with "intrusive magma" that does not reach the surface. When magma erupts out of a volcano, it is "extrusive" and forms either "lava" that flows onto the ground, or "ejecta" that explodes into the air (before falling to the ground as volcanic ash). Intrusion or extrusion of magma produces "igneous" rock, which very different from rock which is produced by dissolved "sediments" accumulating at the bottom of rivers, or "metamorphic" rock which changes its shape and internal structure due to extreme pressures.
When magma or lava cools and takes a permanent form?
Igneous rock is formed.
