- Intrusive rocks are igneous rocks that crystallize below Earth's surface123.Types of intrusive rocks include12453:
- Mafic, felsic, and intermediate intrusive rocks, classified by the relative amounts of feldspars, quartz, and ferromagnesian minerals1.
- Diabase, diorite, gabbro, granite, pegmatite, and peridotite, examples of intrusive rocks with large crystals2.
- Laccolith, dike, batholith, sill, volcanic neck, pipe, and lopolith, examples of intrusive rocks with different shapes and sizes45.

Intrusive rocks are classified the same way extrusive rocks are—according to the relative amounts of feldspars, quartz, and ferromagnesian minerals.www.cliffsnotes.com/study-guides/geology/igneou…We describe these two basic types: Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite.geology.com/rocks/igneous-rocks.shtmlWhen they are formed inside of the earth, they are called intrusive, or plutonic, igneous rocks. If they are formed outside or on top of Earth’s crust, they are called extrusive, or volcanic, igneous rocks. Granite and diorite are examples of common intrusive rocks.www.nationalgeographic.org/encyclopedia/rock-cyc…Basic types of intrusions: 1. Laccolith, 2. Small dike, 3. Batholith, 4. Dike, 5. Sill, 6. Volcanic neck, pipe, 7. Lopolith.en.wikipedia.org/wiki/Igneous_intrusionExamples of intrusive igneous rocks include the intrusions such as dikes, sills, volcanic necks, batholith and laccolith. Contrary to this, an extrusive rock is the one that is formed when the magma from the inside of the Earth is thrown out by a volcanic eruption and it solidifies to form pyroclastics or tuff.www.vedantu.com/geography/intrusive-rock - People also ask

Plutonic rocks form 7% of the Earth's current land surface. Intrusions vary widely, from mountain-range-sized batholiths to thin veinlike fracture fillings of aplite or pegmatite. Batholith: a large irregular discordant intrusionChonolith: an irregularly-shaped intrusion with a demonstrable baseCupola: … See more
Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form intrusions, such as batholiths, dikes, sills, laccoliths, and volcanic necks.
