An intrusion is made of igneous rocks, which form from the solidification of magma below the Earth's surface. Examples include granite, diorite, and gabbro.

How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?

If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.


What do an intrusion and an extrusion tell us about the rock layers?

(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.

Yes, an intrusion is younger than the surrounding rock layers it cuts through. This is because the intrusion is formed after the surrounding rocks have already been deposited and solidified.

Where is igneous rock in magma intrusion into sedimentary rock?

In dikes and sills.


Metamorphic rock is found next to an igneous intrusion what causes that?

Metamorphic rocks are found next to igneous intrusions because the heat and pressure from the intrusion can alter the existing rock, transforming it into a metamorphic rock. The heat and pressure from the magma that forms the igneous intrusion can create conditions suitable for the metamorphism of the surrounding rock. This process can lead to the formation of new minerals and textures in the rock.


What are the relative ages of igneous intrusion and overlying sedimentary rock layers that dome upward?

The igneous intrusion is typically younger than the overlying sedimentary rock layers in a dome structure. The intrusion must have occurred after the deposition of the sedimentary layers and caused them to deform and dome upward due to the force of the molten rock pushing through.


What does magma intrusion means?

Magma intrusion refers to when molten rock (magma) forces its way into existing rock formations beneath the Earth's surface. This intrusion can create new igneous rock formations, as well as potentially lead to volcanic activity if the magma reaches the surface.
