The slab that forms when magma forces itself across rock layers is called a dike.
The slab of volcanic rock that is formed when magma forces itself across rock layers is called a dike. This will eventually build into mountains.
If the magma forces itself along a plane that is parallel to the bedding or foliation planes of the rock strata then (in other words it squeezes between two existing layers) it is a sill. If however it cuts across the bedding or foliation planes it is a dyke. For more information, please see the related links.
Magma fills the gap between plates at DIVERGENT boundaries.

A body of magma that cuts through (and across) adjacent rock. Similar to a secondary vent but it does not strike through the surface. It then hardens and forms rock. It is always younger than the rocks which surround it.
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
