A volcanic laccolith is a mass of igneous rock that is associated with a volcano. It is formed from magma that did not make it to the surface, but that spread out laterally. It forms a bulge in the land around the volcano.

What does magma pushed into a thick sill form?
magma pushed into a thick sill can form what
What is a geologic situation in which a magma does not form a lava?
Lava is simply magma that reaches the surface of the earth. If a magma flow never is emergent while it is still in liquid form, it cannot be termed lava. An example is a volcanic stock or a laccolith that remains beneath the surface entirely.
What is formed when magma begins to form a dome shape which will push the crust outward in a hill formation?
A+ Laccolith
Are there any volcanoes in South Dakota?
Yes, Bear Butte is actually a laccolith, an intrusive body of igneous rock, but any magma or volcanic material has long since eroded away.
Which of these is not a form of volcanic material?
Volcanic Mist

What are the types of pluton?
They include batholith, lopolith, sill, phacolith, laccolith and volcanic neck.

What is magma in a sill which pushes up to form a rock dome called?
Laccolith
What is the layers of rock around a volcano called?
The layers of rock form a dome called a laccolith
What are the factors that might cause magma to form a laccolith instead of a sill?
the chemical and physical particles

A+ Laccolith
Do laccolith features occur when volcano lava cools at the surface?
No. A laccolith is an intrusive feature.
