It's sill or batholith.
It forms a sill.
when magma is squeezed into horizontals craks are called sill
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.
An intrusion.

A Sill is formed when a fluid rock (usually magma but it can be mud or salt) is squeezed in between the layers (usually horizontal) of older rocks before it solidifies in place. A Dike or Dyke is the opposite, here the fluid rock penetrates across the layering of the older rocks. Logically to get the material to form a Sill there must be an accompanying feeder Dyke.
Yes, that's correct. Sills are igneous rock formations that form when magma is intruded horizontally between rock layers and then solidifies underground. If the magma solidifies vertically underneath the surface, it will create a sill structure.
That would be a type of igneous intrusion known as a dike.
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.
A dike is formed when magma intrudes and solidifies in a vertical or near-vertical orientation within pre-existing rock layers. Lava flows, on the other hand, occur when magma erupts onto the surface and flows horizontally along the ground.
Yes, a dike forms when magma intrudes into existing rock layers and solidifies. As the magma cools and solidifies underground, it creates a vertical or near-vertical sheet-like body of igneous rock that cuts across the existing rock layers.
