principle of original horizontality
The principal of cross-cutting relationships involves intrusive rock body younger then the rock into which it intrudes.
The principal of cross-cutting relationships involves intrusive rock body younger then the rock into which it intrudes.
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.
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.

principle of original horizontality
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.
