en.wikipedia.org/wiki/Laccolith

A laccolith is a sheet-like intrusion (or concordant pluton) that has been injected within or between layers of sedimentary rock (when the host rock is volcanic, the laccolith is referred to as a cryptodome).The pressure of the magma is high enough that the overlying strata are forced upward and folded, giving the laccolith a dome or mushroom-like form (or possibly conical or wedge-shape) with ...

Laccolith, in geology, any of a type of igneous intrusion that has split apart two strata, resulting in a domelike structure; the floor of the structure is usually horizontal. A laccolith is often smaller than a stock, which is another type of igneous intrusion, and usually is less than 16 km (10

A round, steep-sided extrusion of very viscous lava that is squeezed from a volcanic vent without major eruption. The lava is too viscous to flow and is composed of rhyolite or dacite. The dome shown in the photo is the vent of the Novarupta eruption of 1912, the largest volcanic eruption of the 20th century. The small dome was overlooked when ...

Felsic magma commonly pools within shallow mushroom-shaped magmatic intrusions, so-called laccoliths or cryptodomes, which can cause both explosive eruptions and collapse of the volcanic edifice. Deformation during laccolith emplacement is primarily considered to occur in the host rock. However, shallowly emplaced laccoliths (cryptodomes) show extensive internal deformation. While deformation ...

Aerial photo of Shaw Butte in central Montana, U.S. It shows the dike that once provided magma to Shaw Butte. This ridge was the magma pipe feeding the intrusion. It moved from nearby Adel Mountain volcanic field to the location of what is now a laccolith (Shaw Butte) through a crack in the bedrock.

As nouns the difference between batholith and laccolith is that batholith is (geology) a large irregular mass of intrusive igneous rock that has melted or forced itself into surrounding strata while laccolith is (geology) a mass of igneous or volcanic rock found within strata which forces the overlaying strata upwards and forms domes.

laccolith A laccolith (also called a plutonic formation or an igneous intrusion) is a formation in which magma (molten rock) is trapped beneath the surface of the Earth and pushes the rock located above it into a dome shape. It has a flat base and a convex upper surface.

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 even along the direction of foliation in metamorphic rock ...
