A sheet of volcanic rock that protrudes into the surrounding layers of rock?

It's called a volcanic sill.


A sheet of igneous rock that protrude into the surrounding layers of rock?

It is called a dike.


Sheets of igneous rock that are parallel to the layers they intrude?

Those are called dykes. Dykes are vertical sheets of igneous rock that cut across existing rock layers. They form when magma solidifies in fractures within the Earth's crust.


The two general shapes of intrusive igneous bodies are?

The two general shapes of intrusive igneous bodies are tabular and massive. Tabular bodies, such as dikes and sills, have a flat, sheet-like shape that forms parallel to the surrounding rock layers. Massive bodies, such as batholiths and stocks, are more irregular in shape and often form deep underground.


What is a tabular concordant intrusive structure?

A tabular concordant intrusive structure refers to a type of igneous intrusion where the orientation of the intrusive body is parallel to the existing layering or structures in the surrounding rock. This results in the intrusion appearing as a tabular or sheet-like feature that runs parallel to the rock layers. The intrusive body is typically discordant to the sedimentary or metamorphic layers but its orientation is concordant.


What is a dolerite dyke?

A dolerite dyke is a sheet-like igneous intrusion that cuts across the surrounding rock formations. It is composed mainly of medium-grained dolerite rock that solidified from magma that intruded into existing rock layers. Dolerite dikes are common in areas with volcanic activity or tectonic movement.


What is the definition of dike in science?

In science, a dike is a sheet of rock that cuts across the structure of adjacent rock layers. Dikes are formed when magma intrudes into existing rock layers and solidifies. They are often made of igneous rock and can vary in thickness and length.


In geology what is the difference between a sill and a dyke?

A sill is a tabular sheet of intrusive igneous rock that forms parallel to the layering of surrounding rock, while a dyke is a vertical or near-vertical sheet of intrusive igneous rock that cuts across the layering of surrounding rock. Sills are horizontal, while dykes are vertical or near-vertical.


What is a tabular discordant pluton?

A tabular discordant pluton is a large igneous intrusion that cuts across existing rock layers in a horizontal or nearly horizontal orientation. This type of pluton is also known as a sheet intrusion due to its tabular shape and discordant nature where it disrupts the surrounding rock layers. Tabular discordant plutons are typically formed when magma is injected into the Earth's crust and spreads laterally to create a flat or sheet-like body of intrusive rock.


What forms when magma forces itself across rock layers?

When magma forces itself across rock layers, it can create igneous intrusions such as dikes (vertical sheet-like intrusions) or sills (horizontal sheet-like intrusions). These intrusions form when magma solidifies as it cools, creating distinctive structures within the surrounding rock layers.


What is a sheet like body that cuts across rock layers and is produced when magma is injected into a fraction is called?

A sheet-like body that cuts across rock layers and is produced when magma is injected into a fracture is called a dike. Dikes are vertical or near-vertical geological formations that form when molten rock intrudes into existing rock layers and solidifies. This process often leads to the formation of igneous rock formations.


Does a dike form when magma forces itself between rock layers and hardens?

Yes, a dike forms when magma intrudes into existing rock layers and solidifies. As the magma cools and solidifies underground, it creates a vertical or near-vertical sheet-like body of igneous rock that cuts across the existing rock layers.
