Volcanic Landforms: Extrusive & Intrusive Volcanic …

WebMar 13, 2024 · Magma leaves the confines of the upper mantle and crust in two major ways: as an intrusion or as an extrusion. An intrusion can form features such as dikes and xenoliths. An extrusion could include lava and volcanic rock. Magma can intrude into a low-density area of another geologic formation, such as a sedimentary rock structure. this is a sheet of rockthat is formed in the fracture of the pre-existing rock. Dyke forms when a mass of magma cuts across the bedding planes and forms a wall-like structure. An example of dyke is one that is found in Jos plateau in Nigeria this has been exposed to the surface through erosion. See more this is formed when a sheet of magma lies along the bedding planes of the earth’s surface. A sill is therefore a horizontal sheet of rock that solidifies from magma that has been injected concordantly between bedding … See more this is a large body of intrusive igneous rock believed to have been crystallized at the considerable depth below the earth’s surface.
