Batholith is the name for a huge igneous intrusion.
A layered intrusion is a large sill-like body of igneous rock which exhibits vertical layering or differences in composition and texture.
Mount Rushmore is a granite batholith, which is a large and deep-seated igneous intrusion that forms beneath the Earth's surface. It is composed of granitic rock, specifically a type called Harney Peak granite.
Intrusive is a term that applies to igneous rocks that form from magma underground such as granite.
Cross cutting relationships define rock formations in geology. When magma enters cracks and crevices in existing rocks and cools it forms what is called an igneous intrusion. The principal of cross cutting relationships means that the igneous intrusion is always younger than the rock it cuts across.
An intrusion is a mass of igneous rock that forms when melted rock moves into cracks in rock layers and then cools.
The minerals had longer to form from the hot magma than did the minerals in the small intrusion, which would have cooled much faster.

When magma below the earth's surface penetrates the crust but does not break the surface, it is called an igneous intrusion.

"layering" As in "layered" igneous intrusion.
A layered intrusion is a large sill-like body of igneous rock which exhibits vertical layering or differences in composition and texture.
It's called a concordant igneous intrusion, or a sill.
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.
Mount Rushmore is a granite batholith, which is a large and deep-seated igneous intrusion that forms beneath the Earth's surface. It is composed of granitic rock, specifically a type called Harney Peak granite.
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.
