Intrusive Landforms (Below the crust) When magma is forced to the surface only a small amount of the mass actually reaches that level. 2 forms of lava: 1. INTRUSIVE VOLCANIC LANDFORMS If this magma cools and solidifies on it’s way to the earths surface, several types of rock masses are formed within the crust depending on the shape and direction of the fractures into which it flows. Home; UPSC Menu Toggle. Several lava flows may accumulate on top of one another for hundreds of meters and over huge areas. Show more Show less . Batholiths are the largest granitic intrusive features formed at depth and can be exopsed to the surface to form major mountain belts. The solidification of magma underground produces distinct landforms known as plutons or intrusive volcanic features. Flashcards. Only $1/month . Craters form as the result of explosive eruptive activity at a volcanic vent where rock, magma, and other... Calderas.
