Batholith - Wikipedia
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.
Igneous intrusion - Wikipedia
A sill is a tabular concordant intrusion, typically taking the form of a sheet parallel to sedimentary beds. They are otherwise similar to dikes. Most are of mafic composition, relatively low in silica, which gives them the low viscosity necessary to penetrate between sedimentary beds.
Plutons: Types of Intrusive Igneous Bodies - Geology In
Large, irregularly shaped plutons are called stocks or batholiths, depending on size. Tabular plutons are called dikes if they cut across existing structures, and sills if they do not. Laccoliths are like sills, except they have caused the overlying …
3.5 Intrusive Igneous Bodies – Physical Geology
Large irregular-shaped plutons are called either stocks or batholiths. The distinction between the two is made on the basis of the area that is exposed at the surface: if the body has an exposed surface area greater than 100 km 2, then it’s a batholith; smaller than 100 km 2 and it’s a stock.
BATHOLITH…, LOPOLITH…, SILL OR DIKE? – INTRUSIONS (2)
Jul 6, 2017 · A ring dike consists of an intrusive body that can be roughly circular in plan and has steeply dipping to almost vertical outer margins. Ring dikes are often the results of magma intruding ring faults after a caldera collapse. Ardnamurchan “ring dike” in NW Scotland is an example for the difficulty of determining the nature of such intrusions.
Igneous and Volcanic Rock Features - Geology.com
Dike. A tabular igneous intrusion that crosses through other (layered or non-layered) rocks at a steep angle. Dikes can occur alone or in sets and may be comprised of light (high-silica) or dark (low-silica) rocks, or any composition in between.

Apr 24, 2024 · A dyke can be horizontal and a sill can be vertical (if the bedding is vertical). A large dyke can be seen in Figure \(\PageIndex{3}\). A laccolith is a sill-like body that has expanded upward by deforming the overlying rock.

A dike can be horizontal and a sill can be vertical (if the bedding is vertical). A large dike can be seen in Figure 4.4.3. A laccolith is a sill-like body that has expanded upward by deforming the overlying rock.
Sill (geology) - Wikipedia
In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A sill is a concordant intrusive sheet, meaning that it does not cut across preexisting rock beds.
