They are usually found within another sedimentary unit, but can also form within an igneous or metamorphicmass. Clastic dikes can form in several ways: 1. … Ver mais Igneous dikes form as magma is pushed up through vertical rock fractures, where it then cools and crystallizes. They form in sedimentary, metamorphic and igneous rocks and can force open the fractures as they cool. … Ver mais Ring dikes are intrusive igneous sheets that are circular, oval or arcuate in overall trend.

A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge.
