What are the four basic types of plutons?
ash, dust, cinders, and volcanic blocks
batholiths, yikes, basalts, and hot spots
batholiths, yikes, sills, and laccoliths
magma, lava, gases, and crystals

batholiths, d ikes, sills, and laccoliths

Explanation:

The plutons represent type of igneous intrusive rock formations. The word brings in some confusion as it is used differently around the world, but the general meaning of the word is that it represents a non-tabular intrusive body.

The plutons are often divided into four basic types:

- batholiths

- d ikes

- sills

- laccoliths

All of the plutons are forming deep into the ground. The magma cools off slowly into the crust and it forms a particular intrusive igneous formation. The laccoliths have the shape of a lens. The d ikes are pipe like and vertical. The sills are linear and horizontal. The batholiths are enormous and they lie below the other plutons, being the basis for them.
