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.
How does igneous intrusion end up as a hill?
Basically, igneous intrusion involves the solidifying of magma when it cools in the crust of the Earth. When magma rises through the crust, it intrudes into the existing sedimentary rock layers and forms a hill. The surounding rock may be more prone to erosion and wear away leaving the intrusion jutting above the (eroded) surroundings.
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.
A laccolith is an example of a?
A laccolith is an example of an igneous intrusion, which is a body of intrusive igneous rock that forms by magma uplifting and pushing overlying rock layers.
What is the feature that is formed when lava cuts across rock layers and hardens?
Lava that cuts across rock layers hardens to form a feature called a Dike.
What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers
What is the geologic term for a tabular body of igneous rock that is parallel to the surrounding rock layers?
It's called a concordant igneous intrusion, or a sill.
What is formed when magma that is squeezed into a generally vertical crack that cuts across layers and hardens?
That would be a type of igneous intrusion known as a dike.
How would you classify an igneous intrusion that is tabular and discordant?
An igneous intrusion that is tabular and discordant is classified as a dyke. Dykes are vertical or steeply inclined sheets of magma that cut across the existing rock layers, indicating that they intruded after the formation of those layers. This discordant nature contrasts with sills, which are tabular intrusions that parallel the bedding of the surrounding rock.
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.
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 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 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 igneous intrusion in relation to the sedimentary rock layers it passes through?
It is younger than them.
What feature is formed when lava cuts across rock layers and hardens?
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.
When magma cuts across another rock and hardens the resulting formation is called an?
When magma cuts across another rock and hardens, the resulting formation is called an "intrusion" or "igneous intrusion." This occurs when molten rock, or magma, forces its way into pre-existing rock layers and solidifies, typically forming structures such as dikes or sills. Intrusions are important in understanding geological processes and the history of the Earth’s crust.
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.
