What would a vertical wall of intrusive rock filling in a crack or fissure be referred to as?

Batholith

Laccolith

Di k e

Guyot

I think the answer is Di k e. It can be found between the cracks or fractures of rocks. It crystallizes when cooled. A batholith is an igneous rock while Laccolith can be igneous or sedimentary, both are big rocks that are different from a di k e.
