Younger than the rock it intrudes into
With sedimentary rocks, young ones are usually on top of older ones. Where igneous rocks intrude into others, the intrusions must be younger than the surrounding rocks.
Cross cutting relationships define rock formations in geology. When magma enters cracks and crevices in existing rocks and cools it forms what is called an igneous intrusion. The principal of cross cutting relationships means that the igneous intrusion is always younger than the rock it cuts across.
The principal of cross-cutting relationships involves intrusive rock body younger then the rock into which it intrudes.

The melted rock of the igneous intrusion pushed its way into cracks and made previously existing rock weaker. The intrusions only became rock when they cooled and solidified, therefore they are younger than the rocks in which they are embedded.
