Volcanic Landforms
Volcanic landforms are geographical features created by volcanic activity, classified into extrusive and intrusive types based on whether magma cools inside or outside the Earth’s crust.
Intrusive Volcanic Landforms
Intrusive landforms are formed when magma cools and solidifies beneath the Earth’s surface. These include various features:
- Batholiths: Large magmatic bodies that cool deep within the crust, often forming large domes. They appear on the surface after denudation. An example is the granitic batholiths found in the Sierra Nevada.
- Laccoliths: Dome-shaped bodies formed at deeper levels, resembling volcanic domes. These can be seen in the Karnataka Plateau.
- Lopoliths: Saucer-shaped intrusions formed when lava moves horizontally along weak planes. They are concave upward.
- Phacoliths: Wavy, intrusive rock masses found at the base of synclines or top of anticlines.
- Sills and Dykes: Horizontal and vertical sheets of intrusive rocks, respectively. Sills are horizontal, while dykes are vertical or steeply inclined rock formations. A notable example is the Deccan Traps in Western Maharashtra.
These intrusive landforms are primarily found in areas like the Deccan Plateau.

Volcanic processes are dynamic geological phenomena that shape the Earth's surface through the eruption of molten rock, ash, and gases. These processes give rise to both extrusive and intrusive landforms. Extrusive landforms, like conical hills, form outside the Earth's surface, while intrusive landRead more
Volcanic processes are dynamic geological phenomena that shape the Earth’s surface through the eruption of molten rock, ash, and gases. These processes give rise to both extrusive and intrusive landforms. Extrusive landforms, like conical hills, form outside the Earth’s surface, while intrusive landforms, such as batholiths, develop within the Earth’s crust.
Intrusive Landforms that Emerge from Volcanic Processes
Intrusive landforms are structures that result from the solidification of magma beneath the Earth’s surface. They can take various shapes and sizes, each with its own unique characteristics. Different such landforms can be explained as follows:
Understanding this myriad of intrusive landforms emerging from volcanic processes not only provides insights into the geological history of a region but also plays a crucial role in various scientific fields, including geology, mineral exploration, and even geothermal energy production.
