How are intrusive features classified?
Intrusive features are classified by their shape, size, and relationship to the surrounding rock layers.

Intrusive features are classified by their shape, size, and relationship to the surrounding rock layers. A dike is a pluton that forms when magma is injected into fractures, cutting across preexisting rock layers.Click to see full answer. Accordingly, what are intrusive features?Intrusive volcanism is when magma is forced into the rocks that make up the Earth’s crust. Major features formed by intrusive volcanicity include: batholith, laccolith, dyke, pipe and sill. Batholiths: Have large scale magma that has been solidified at the base of the mountain.Beside above, how is a pluton classified? Magmas that crystallize before eruption produce bodies of rock called INTRUSIONS or PLUTONS. Such bodies are classified based upon three characteristics: 1) shape of the rock body, 2) exactly how the igneous rocks were intruded or emplaced into the rocks surrounding them, and 3) overall size of the body. Also question is, what are the major intrusive igneous bodies? Types of intrusive igneous rocks are granite and basalt . The diagram above shows you a large intrusive igneous body called a batholith. A batholith is the largest of the intrusive bodies. They are larger than 100 square kilometers and usually form granite cores.What factors determine the type of volcanic eruptions?Magma composition, magma temperature, and the amount of dissolved gasses in the magma.
