Sills
The main types of plutons are batholiths, stocks, laccoliths, dikes, and sills. Batholiths are large intrusions exposed over a large area, while stocks are smaller intrusions. Laccoliths are mushroom-shaped intrusions, dikes are tabular intrusions that cut across existing rock layers, and sills are tabular intrusions that parallel existing rock layers.
Igneous intrusions injected between horizontal layers are known as sills. Sills are tabular intrusions that are typically parallel to the layering of the existing rock formations. They are formed when magma is injected horizontally into existing rock layers and solidifies underground.
Dikes are tabular intrusions that cut across existing rock layers. Sills are tabular intrusions that form parallel to existing rock layers. Laccoliths are mushroom-shaped intrusions with a flat base and a dome-like top. Batholiths are large intrusive rock bodies that cover at least 100 square kilometers in surface exposure. Volcanic necks are columnar intrusions that form when magma solidifies in a volcano's vent.
These are likely to be fractures or faults in the rock, caused by tectonic forces or other geological processes. Intrusions can include dikes or veins that form when magma or mineral-rich fluids force their way into existing rock layers. These features provide valuable information about the history and tectonic forces that have affected the rock.
Dikes: vertical or near-vertical intrusions that cut across existing rock layers. Sills: horizontal intrusions that occur between existing rock layers. Laccoliths: mushroom-shaped intrusions that cause the overlying rock to bulge upwards. Batholiths: large, dome-shaped intrusions that extend deep into the Earth's crust.
Metamorphic rock
The main types of plutons are batholiths, stocks, laccoliths, dikes, and sills. Batholiths are large intrusions exposed over a large area, while stocks are smaller intrusions. Laccoliths are mushroom-shaped intrusions, dikes are tabular intrusions that cut across existing rock layers, and sills are tabular intrusions that parallel existing rock layers.
Small intrusions cutting across existing rock are geological features known as dikes. Dikes are formed when magma intrudes into pre-existing rock layers, solidifying as it cools. They typically have a vertical or steeply inclined orientation and can vary in size and composition. Dikes can provide important information about the geological history and volcanic activity of an area.

No, compressed layers of sedimentary rocks are not known as intrusions. Intrusions are igneous rock formations that form when magma is forced into existing rock formations and solidifies underground. Sedimentary rocks are formed through the accumulation and compression of sediments.
These are known as sills.
intrusions or intruded formations.
Quartzite is a Metamorphic Rock that undergos extreme heat and pressure forcing pre-existing rocks to recrystalize. It forms through contact metamorphism. It's formed at an igneous intrusion cutting through existing rock in a small area; usually along cooled igneus intrusions.
