Five intrusive igneous rock structures?
Dikes: Tabular, discordant intrusive igneous bodies that cut across existing rock layers. Sills: Tabular, concordant intrusive igneous bodies that form parallel to existing rock layers. Laccoliths: Intrusive igneous bodies that are lens-shaped and have uplifted the overlying rock layers. Batholiths: Large intrusive igneous bodies that cover at least 100 square kilometers. Stocks: Small intrusive igneous bodies that are less than 100 square kilometers in size.
What is the difference between a dike and a vein deposit?
A dike is a tabular body of intrusive rock that cuts across pre-existing rock layers, while a vein deposit is a narrow, linear fracture filled with minerals that are precipitated from hydrothermal fluids. Dikes are igneous in origin, whereas vein deposits are often associated with hydrothermal mineralization.
Is gabbro a dike?
Gabbro is an intrusive mafic igneous rock. A dike is a type intrusive igneous structure and is not associated with any particular type of igneousn rock. Gabbro can form dikes, sills, and other structures.
Small intrusions parallel to existing rock?
These small intrusions are likely dikes, which are vertical or near-vertical sheet-like bodies of intrusive igneous rock that cut across the existing rock layers. They are formed when magma is injected into existing fractures and solidifies underground. Dikes can provide insight into the geological history of an area and the direction of magma flow.

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.
What kind of igneous formations are sills dikes and plutons?
Sills, dikes, and plutons are types of igneous formations that result from the intrusion of magma into pre-existing rock. Sills are horizontal or gently inclined sheets of magma that intrude between layers of sedimentary rock. Dikes are vertical or steeply inclined intrusions that cut across existing rock layers. Plutons are large, irregularly shaped bodies of intrusive igneous rock that form deep within the Earth's crust, often resulting from the slow crystallization of magma over time.
What geologic law is applied if an igneous intrusion is observed through a layer of sedimentary rock?
The principle of cross-cutting relationships is applied in this case. It states that the intrusion must be younger than the sedimentary rock it cuts through, as the igneous rock is "cutting across" pre-existing layers. This helps in determining the relative ages of the rocks involved.
What is the term for a tabular igneous pluton that occurs in an orientation that is discordant with the bedding surfaces of adjacent sedimentary rocks?
The term for a tabular igneous pluton that is oriented discordantly to the bedding surfaces of adjacent sedimentary rocks is called a "dike." Dikes are typically vertical or steeply inclined and cut across pre-existing rock layers, contrasting with sills, which are parallel to the bedding.
What are the four basic types of plutons?
The four basic types of plutons are batholiths, stocks, dikes, and sills. Batholiths are large masses of intrusive igneous rock that form deep underground, while stocks are smaller intrusions. Dikes are tabular bodies of igneous rock that cut across existing rock layers, and sills are tabular bodies that intrude between existing rock layers.
What is magma that hardens after being forced into a crack across rock?
Magma that hardens after being forced into a crack across rock is called a dike.

The largest intrusive igneous bodies are called?
Batholiths. They are sometimes 100 kilometres across and from the side, look like an upside-down ship.
