batholith

Explanation:

    Plutonic rocks can have various deposit modes. Batoliths are a mode of deposit of plutonic rocks, characterized by their large mass, which surface to the surface in large stretches, generally larger than 100 square kilometers. Contact with the enclosing rocks is an uneven surface, generally discordant with these rocks. If the diameter of the batolith is a few kilometers, it is called stock. The batoliths increase in length as they sink, without defining a lower limit. Sometimes the batoliths have well-defined outer boundaries, with a true contact surface between the plutonic and the enclosing rock, but sometimes the boundaries are diffuse and gradual, passing from one rock to another by intermediate rocks.

    A batolith can emit irregular prolongations, called apophyses, of long length and relatively small section, that pierce the enclosing rocks in the most diverse directions.

   One of the largest known batoliths is the Coast Ranger, Canada, which is 2000 kilometers long and 200 kilometers maximum width.
