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 km 2 (40 sq mi) in area, [1] that forms from cooled magma deep in the Earth's crust.

Batholith, large body of igneous rock formed beneath the Earth’s surface by the intrusion and solidification of magma. It is commonly composed of coarse-grained rocks (e.g., granite or granodiorite) with a surface exposure of 100 square km (40 square miles) or larger.

2018年6月2日 · What Is A Batholith? Ladakh batholiths in the Himalayas. A batholith is a giant mass of intrusive igneous rock that forms when magma collects and cools deep in the earth’s crust without being exposed to the surface.

2015年9月7日 · 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. The magma cools beneath the earth’s surface, forming a rock structure that extends at least one hundred square kilometers across (40 square miles), and extends to ...

Batholith: Large body of plutonic rock mainly composed of granodiorite and granite, typically occurring in the magmatic belt above subduction zones. By far the largest and most amorphous intrusion is the batholith, which is a subterranean igneous body of enormous size and perhaps of unknown depth.

2018年6月8日 · Batholith. Batholiths are large bodies of intrusive igneous rock. Formed when magma cools and crystallizes beneath Earth's surface, batholiths are the largest type of pluton. By definition, a batholith must cover at least 39 mi 2 (100 km 2), although most are even larger. Many batholiths cover hundreds to thousands of square miles.

The batholith is a large irregular mass of intrusive igneous rocks that forces themselves in surrounding strata, and laccolith is a mass of igneous or volcanic rock within strata. Batholith and laccoliths are part of igneous rocks and volcanic landforms.

A batholith is a large mass of intrusive igneous rock that forms from the crystallization of magma deep within the Earth's crust. These immense structures often cover over 100 square kilometers and can extend several kilometers into the crust, showcasing a variety of rock types.

A batholith is formed when many plutons converge to form a huge expanse of granitic rock. Some batholiths are mammoth, paralleling past and present subduction zones and other heat sources for hundreds of kilometers in continental crust .

Batholith was first used by Suess (1901) to describe a “stock”- or “shield”-shaped igneous mass either intruded into country rock, or formed by the fusion of older basement.
