According to the principle of cross-cutting relationships, an intrusive rock body is younger than the rocks it intrudes into. This is because the intrusion must be younger in order to squeeze into the pre-existing rocks.
Igneous rock is always younger than the rock layer it cuts through because of the principle of cross-cutting relationships in geology. When magma intrudes into pre-existing rock layers and solidifies, it disrupts those layers, indicating that the intrusion occurred after the formation of the surrounding rock. Therefore, any igneous rock that penetrates or cuts through sedimentary layers must be younger than those layers. This principle helps geologists determine the relative ages of rock formations.
A pluton that cuts across existing rock layers is known as a cross-cutting pluton. This occurs when magma intrudes into pre-existing rock formations and solidifies, creating an igneous body that disrupts the original stratigraphy. The principle of cross-cutting relationships in geology states that the features that cut across others are younger than the rocks they intersect. Examples of such plutons include dikes and stocks.
The principal of cross-cutting relationships involves intrusive rock body younger then the rock into which it intrudes.

The principle you are referring to is the principle of cross-cutting relationships. It states that any feature that cuts across a rock must be younger than the rock it cuts across. This applies to intrusive rock bodies, which are younger than the rocks they intrude into.
According to the principle of cross-cutting relationships, an intrusive rock body is younger than the rocks it intrudes into. This is because the intrusion must be younger in order to squeeze into the pre-existing rocks.
Younger than the rock it intrudes into
When a granite intrusion occurs within a layer of younger limestone, the granite is considered older than the surrounding limestone. This is because intrusive rocks form before surrounding sedimentary rocks. If the intrusion occurs within older limestone, then the limestone is considered older than the granite.
Law of cross-cutting relationships
An igneous intrusion is younger because it forms after the surrounding rocks have already solidified. Magma forces its way into the existing rock layers, and once it cools and solidifies, it is considered younger than the surrounding rocks. This relationship helps geologists determine the sequence of geological events.
No, intrusive rocks are typically younger than the rocks they cut across. This is because they are formed when molten rock (magma) solidifies beneath the Earth's surface, usually after the surrounding rocks have already formed.
