What type of intrusive features form when magma is injected into fractures cutting across preexisting rock layers?
A fault
Lava that cuts across rock layers hardens to form a feature called?
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.
Is dike a type of lava flow?
A dike is not a type of lava flow, but rather a sheet-like intrusion of igneous rock that cuts across existing rock layers. Dikes form when molten rock (magma) is injected into fractures in the Earth's crust and crystallizes before reaching the surface.
A sheet-like body that cuts across rock layers and is produced when magma is injected into a fracture is called a?
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.
What are formed by magma that fills cracks that cut across existing rock layers?
Magma that fills cracks cutting across existing rock layers forms igneous intrusions known as dikes. These dikes are vertical or steeply inclined structures where the magma solidifies after being injected into the fractures. As the magma cools, it crystallizes, creating a rock that can be composed of various minerals depending on its composition. Dikes are important geological features that provide insights into the history of volcanic activity and the movement of magma within the Earth's crust.
Which type of intrusive feature when magma is injected into fractures cutting across preexisting rock layers?
sill
Which type of intrusive feature forms when when magma is injected into fractures cutting across rock layers?
sill
Which type of intrusive feature forms when magma is injected into fractures cutting across preexisting rock layers?
Dikes are intrusive features that form when magma is injected into fractures that cut across preexisting rock layers. Dikes are tabular structures that can range in width from a few centimeters to tens of meters and can extend for kilometers.
What is cross-cutting relationship?
A crosscutting feature occurs when a rock or body of sediment cuts across, through fractures, faults, or magma. Any feature that cuts across must be younger than the rock or sediment that it cuts across.
What type of intrusive features form when magma is injected into fractures cutting across preexisting rock layers?
A fault
What is the principle of cross cutting relationships?
Crosscutting includes fractures (cracks in rocks), faults (fractures where movement has occurred), or masses of magma that cut across preexisting rocks before cooling. Any crosscutting feature must be younger than the rock or sediment it cuts across.
Unlike other types of plutons a dike forms?
A dike forms when magma is injected into a crack in the rock and solidifies underground. It is characterized by a tabular shape that cuts across existing rock layers. Dikes are typically composed of igneous rock, such as basalt or granite.
