Answer:
This is a d/yke
Explanation:
The description of events in the problem is similar to that of an igneous intrusion through a sedimentary rock layers.
A d/yke is an igneous intrusion that cross cut a rock sequence vertically. The orientation of d/yke is usually against the bedding plane of the rock it cuts through. D/ykes are usually younger than the rocks they cut through.
The hole through the layers can be pictured as a weakness plane which can form as a result of fractures in the rock. The fractures allow for intruding magma to pass and move through. When the magma cools and solidifies within the fractures, it results in a d/yke.
D/ykes are usually of great economic importance.
