A pluton that cuts across existing rock layers is known as a cross-cutting pluton. This occurs when magma intrudes into pre-existing rock formations and solidifies, creating an igneous body that disrupts the original stratigraphy. The principle of cross-cutting relationships in geology states that the features that cut across others are younger than the rocks they intersect. Examples of such plutons include dikes and stocks.
A sill is a type of pluton that is completely parallel to the rock layers into which it intrudes. Sills are formed when magma is injected between pre-existing rock layers and then solidifies. The resulting igneous rock body is typically flat-lying and can be found sandwiched between the surrounding rock layers.
a dike. Dikes are vertical or near-vertical igneous intrusions that cut across the existing rock layers. They form when magma is forced into fractures and then cools and solidifies underground.
A dike is formed when lava cuts across rock layers and hardens. This igneous intrusion results in a narrow, tabular rock formation that can be exposed on the Earth's surface due to erosion or uplift.
If the magma forces itself along a plane that is parallel to the bedding or foliation planes of the rock strata then (in other words it squeezes between two existing layers) it is a sill. If however it cuts across the bedding or foliation planes it is a dyke. For more information, please see the related links.
A sheet-like body that cuts across rock layers and is produced when magma is injected into a fracture is called a dyke. Dykes are typically vertical or steeply inclined and can vary in thickness. They are formed when magma forces its way through existing rock, solidifying as it cools. This geological feature is important for understanding the history of volcanic activity and the movement of magma within the Earth's crust.

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.
A discordant intrusion is known as a dyke. A larger intrusion may also be a pluton or batholith, which both also cut across rock strata. A sill is an intrusion which is concordant, and goes between the strata. This does not necessarily mean that it is horizontal.
The dike likely formed after the layers of sandstone, as it cuts across them. Dikes form when magma intrudes into existing rock layers and solidifies underground before being exposed at the surface through erosion. Therefore, the dike is a later geological event compared to the formation of the original sandstone layers in the Grand Canyon.
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.

Lava that cuts across rock layers hardens to form a feature called a Dike.
Dikes are always younger than the surrounding rock layers. The same holds true for any kind of intrusion. It will always be younger than anything that it is intruding into. To put it simply, you can't force an object into a bed of rock unless the bed of rock is already there.

an intrusive body of magma that cuts across layers of rock
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.
