It is called a dike.
What else can I help you with?
A sheet of igneous rock that protrudes into the surrounding layers of rock?
It is called a dike.
Sheets of igneous rock that are parallel to the layers they intrude?
A sheet of igneous rock that protrudes into the surrounding layers of rock is called a dike. Dikes are most often horizontal sheets that can form in many layers.
A sheet of volcanic rock that protrudes into the surrounding layers of rock?
It's called a volcanic sill.
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.
What is a crack that has been filled in by magma and hardens parallel to existing rock layers?
A crack that has been filled in by magma and hardens parallel to existing rock layers is known as a "sill." Sills are formed when magma intrudes between pre-existing rock layers and solidifies, resulting in a horizontal or nearly horizontal sheet of igneous rock. This process can create distinctive geological features and is an important aspect of igneous rock formation.
In geology what is the difference between a sill and a dyke?
Both of these are called igneous intrusions. They form when liquid magma forces its way into cracks in existing rocks and sets. If the resulting band of rock is basically vertical it is called a dyke, and if it is more horizontal it is a sill.
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.
Which intrusive igneous body is typically tabular and concordant?
The intrusive igneous body that is typically tabular and concordant is known as a "sill." Sills form when magma intrudes between existing layers of rock, spreading horizontally and parallel to the bedding planes. This results in a flat, sheet-like structure that can vary in thickness and extent. Sills differ from dikes, which are discordant and cut across existing rock layers.
