GENERAL GEOLOGY

Detailed explanation-1: -A batholith is a very large mass of intrusive igneous rock that forms and cools deep in the Earth’s crust. An igneous rock is a type of rock formed through the cooling of lava or magma. The term ‘batholith’ comes from the Greek words bathos, meaning ‘depth, ’ and lithos, meaning ‘rock.

Detailed explanation-2: -Lava Domes-Lava domes form where thick (viscous) magma erupts to the surface forming a steep dome-shaped landform.

Detailed explanation-3: -A batholith (from Ancient Greek bathos ‘depth’, and lithos ‘rock’) is a large mass of intrusive igneous rock (also called plutonic rock), larger than 100 km2 (40 sq mi) in area, that forms from cooled magma deep in Earth’s crust.

Detailed explanation-4: -Despite sounding like something out of Harry Potter, a batholith is a type of igneous rock that forms when magma rises into the earth’s crust, but does not erupt onto the surface.

Detailed explanation-5: -Intrusive igneous rocks that form at depth within the crust are termed plutonic (or abyssal) rocks and are usually coarse-grained.
