A dike
When magma hardens between layers of rock, it forms intrusive igneous rock structures known as dikes or sills. Dikes cut across the existing rock layers, while sills form parallel to them. These formations are typically formed when magma solidifies underground before reaching the surface.
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 concordant intrusive igneous feature like a sill can form when magma hardens between horizontal layers of rock. Sills are tabular bodies that are parallel to the surrounding rock layers.
It forms a sill.
Magma that hardens after being forced into a crack across rock is called a dike.
Lava that cuts across rock layers hardens to form a feature called a Dike.
Lava that cuts across rock layers hardens to form a disk.
That would be a type of igneous intrusion known as a dike.
When magma hardens between layers of rock, it forms intrusive igneous rock structures known as dikes or sills. Dikes cut across the existing rock layers, while sills form parallel to them. These formations are typically formed when magma solidifies underground before reaching the surface.
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
