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 else can I help you with?
Are sills tabular discordant bodies that are produced when magma is injected into fractures?
Yes, sills are tabular discordant bodies formed when magma intrudes into pre-existing fractures and solidifies between layers of existing rock. They are characterized by their flat, parallel orientation with the surrounding rock layers.
Are sills and dikes an example of intrusive igneous activity?
Yes they are. Dikes are tabular discordant bodies that are produced when magma is injected into fractures and Sills are tabular plutons formed when magma is injected along sedimentary bedding surfaces.
What is the term for a tabular igneous pluton that occurs in an orientation that is discordant with the bedding surfaces of adjacent sedimentary rocks?
The term for a tabular igneous pluton that is oriented discordantly to the bedding surfaces of adjacent sedimentary rocks is called a "dike." Dikes are typically vertical or steeply inclined and cut across pre-existing rock layers, contrasting with sills, which are parallel to the bedding.
Which intrusive igneous body is typically tabular and concordant?
The intrusive igneous body that is typically tabular and concordant is known as a "sill." Sills form when magma intrudes between existing layers of rock, spreading horizontally and parallel to the bedding planes. This results in a flat, sheet-like structure that can vary in thickness and extent. Sills differ from dikes, which are discordant and cut across existing rock layers.
A vertical intrusion is a?
A vertical intrusion is a body of igneous rock that has forced its way up through the layers of pre-existing rock in a vertical orientation. These intrusions are known as dikes if they are relatively narrow and tabular in shape, or as volcanic necks if they are more massive and represent the remnants of ancient volcanic vents.
What is a tabular discordant pluton?
A tabular discordant pluton is a large igneous intrusion that cuts across existing rock layers in a horizontal or nearly horizontal orientation. This type of pluton is also known as a sheet intrusion due to its tabular shape and discordant nature where it disrupts the surrounding rock layers. Tabular discordant plutons are typically formed when magma is injected into the Earth's crust and spreads laterally to create a flat or sheet-like body of intrusive rock.
What is a tabular concordant intrusive structure?
A tabular concordant intrusive structure refers to a type of igneous intrusion where the orientation of the intrusive body is parallel to the existing layering or structures in the surrounding rock. This results in the intrusion appearing as a tabular or sheet-like feature that runs parallel to the rock layers. The intrusive body is typically discordant to the sedimentary or metamorphic layers but its orientation is concordant.
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.
Are sills tabular discordant bodies that are produced when magma is injected into fractures?
Yes, sills are tabular discordant bodies formed when magma intrudes into pre-existing fractures and solidifies between layers of existing rock. They are characterized by their flat, parallel orientation with the surrounding rock layers.

Five intrusive igneous rock structures?
Dikes: Tabular, discordant intrusive igneous bodies that cut across existing rock layers. Sills: Tabular, concordant intrusive igneous bodies that form parallel to existing rock layers. Laccoliths: Intrusive igneous bodies that are lens-shaped and have uplifted the overlying rock layers. Batholiths: Large intrusive igneous bodies that cover at least 100 square kilometers. Stocks: Small intrusive igneous bodies that are less than 100 square kilometers in size.
What is an intrusive igneous rock body that is tabular and concordant.?
sill
A vertical intrusion is a?
A vertical intrusion is a body of igneous rock that has forced its way up through the layers of pre-existing rock in a vertical orientation. These intrusions are known as dikes if they are relatively narrow and tabular in shape, or as volcanic necks if they are more massive and represent the remnants of ancient volcanic vents.
Magma that hardnes vertically underneath the surface will form a sill?
From your statement it sounds like you are referring to an igneous dyke rather than a sill, however see the following: A sill is a sheet of intruded magma that forms between to layers of older "country" rock. This is technically described as a "concordant sheet intrusion". If it is later over turned due to tectonic folding it may be vertical but as it was originally emplaced between and parallel to pre-existing rock layers, it is still an igneous sill! However if the intrusion cross cuts the bedding planes of the country rock - known as a discordant intrusion (and was originally (sub)vertical at the time of emplacement) it is known as a dyke. For more information please see the related link.
What forms when magma flows horizontally along rock layers?
When magma flows horizontally along rock layers, it can form a feature called a sill. Sills are tabular igneous intrusions that are parallel to the surrounding rock layers. They are typically formed when magma is injected between existing rock layers and cools and solidifies underground.
