What is an igneous intrusion that forms between two layers of sedimentary rock?
An igneous intrusion that forms between two layers of sedimentary rock is known as a "sill." Sills occur when molten magma intrudes horizontally between existing rock layers, solidifying into igneous rock as it cools. This process can create distinctive geological features and may alter the surrounding sedimentary layers through heat and pressure. Sills often exhibit a uniform thickness and can vary in composition, depending on the magma source.
What type of rock is a laccolith?
A laccolith is a type of igneous rock formation that is created when magma intrudes between layers of sedimentary rock, causing the overlying layers to arch upward. It is classified as an intrusive igneous rock.
Which numbered rock layers are younger than the ignewous intrusion layer?
To determine which numbered rock layers are younger than the igneous intrusion layer, you would need to refer to a specific geological cross-section or diagram. Generally, in geology, igneous intrusions are younger than the surrounding sedimentary layers because they form after the existing layers have been deposited. Therefore, any rock layers that are located above the igneous intrusion in the stratigraphic sequence would be considered younger.
What is a loccolith?
A loccolith is a type of igneous intrusion in which magma is injected between layers of sedimentary rock, causing the overlying rock layers to bulge upwards in a dome shape. Loccoliths are typically characterized by a flat base and a domed top.
Did the fault occur before or after the igneous intrusion?
To determine whether the fault occurred before or after the igneous intrusion, geologists typically analyze the relationships between the rock layers and the intrusion. If the fault cuts through the igneous rock, it indicates that the fault occurred after the intrusion. Conversely, if the intrusion is found within the fault zone or is displaced by the fault, it suggests that the fault predates the igneous intrusion.
Why portions of the sedimentary rock layers have the symbol for contact metamorphism?
the rock layers were eroded at the interface between the igneous intrusion and the sedimentary rocks.
What are the relative ages of igneous intrusion and overlying sedimentary rock layers that dome upward?
The igneous intrusion is typically younger than the overlying sedimentary rock layers in a dome structure. The intrusion must have occurred after the deposition of the sedimentary layers and caused them to deform and dome upward due to the force of the molten rock pushing through.

What is the The age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passes?
It is younger.
What is the age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passed?
It is younger.
What is the age of an igneous intrusion in relation to the sedimentary rock layers it passes through?
It is younger than them.
How can igneous rock disturb sedimentary rock layers?
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.

What is a horizontal intrusive igneous body that forms between sedimentary rock layers?
A sill is a horizontal intrusive igneous body that forms between sedimentary rock layers. Sills are formed when magma intrudes parallel to the layering of the surrounding rocks and solidifies underground.
What is a loccolith?
A loccolith is a type of igneous intrusion in which magma is injected between layers of sedimentary rock, causing the overlying rock layers to bulge upwards in a dome shape. Loccoliths are typically characterized by a flat base and a domed top.
Which is a process involved in the information of sedimentary rocks extrusion . intrusion . compaction?
The process involved in the formation of sedimentary rocks is compaction. Compaction occurs when sediments accumulate in layers and are buried under additional layers, leading to increased pressure that reduces the space between sediment particles. This process helps to cement the sediments together, forming solid rock. Extrusion and intrusion are terms related to igneous rocks, not sedimentary ones.
