When there is an igneous intrusion and a fault line which one is younger?
That depends! If the fault line cross cuts the igneous intrusion causing the intrusion to be displaced on either side of the fault and forming a broken mass of rock within the intrusion known as a fault breccia then the fault is younger than the intrusions, as the intrusion must have already existed for the fault to cause it's displacement. If on the other hand the igneous intrusion cross cuts the fault and is un-deformed then it is probable that it is younger than the fault.
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.
What statement best describes an igneous intrusion?
An igneous intrusion is formed when molten rock (magma) is forced into preexisting rock and solidifies underground. Over time, the surrounding rock erodes away, exposing the igneous intrusion at the Earth's surface. Intrusions can take various shapes and sizes, such as dikes, sills, and laccoliths.
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.
Metamorphic rock is found next to an igneous intrusion what causes that?
The heat from the intrusion has baked the host rock, altering its physical characteristics. Fluids heated by the intrusion can also alter the chemistry of the host rock by adding ions present in the heated fluids.
What do you call the layering in igneous rocks?
"layering" As in "layered" igneous intrusion.
What is a large igneous intrusion called?
A large igneous intrusion is called a pluton. Plutons are formed when molten rock (magma) solidifies beneath the Earth's surface, resulting in large bodies of igneous rock. Examples of plutons include batholiths, stocks, and laccoliths.
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.
When there is an igneous intrusion and a fault line which one is younger?

If the fault line cross cuts the igneous intrusion causing the intrusion to be displaced on either side of the fault and forming a broken mass of rock within the intrusion known as a fault breccia then the fault is younger than the intrusions, as the intrusion must have already existed for the fault to cause it's displacement. If on the other hand the igneous intrusion cross cuts the fault and is un-deformed then it is probable that it is younger than the fault.
What kind of a rock is an intrusion made of?
igneous rock
Why are the rocks in a large igneous intrusion coaser grained than the rocks in a small igneous intrusion at the same depth?
The minerals had longer to form from the hot magma than did the minerals in the small intrusion, which would have cooled much faster.
How does the age of an igneous extrusion compare with the rock into which it was extruded?
An igneous intrusion is younger than the rock into which it intruded.
Where is igneous rock in magma intrusion into sedimentary rock?
In dikes and sills.
What is an antonym for batholith?
The antonym for batholith is small igneous intrusion or dyke.
What is the largest igneous intrusive body?
The largest type of intrusion is the pluton.

The surounding rock may be more prone to erosion and wear away leaving the intrusion jutting above the (eroded) surroundings.
What kind of rock is an intrusion made of?
An intrusion is a mass of igneous rock that forms when melted rock moves into cracks in rock layers and then cools.
