Principle of cross-cutting relationships
posted by admin in UncategorizedA rock or fault is younger than any rock (or fault) through which it cuts. This principle was developed by James Hutton.
- Example
In a series of horizontal sedimentary beds, there is an igneous dyke which cuts vertically through them.
The dyke is younger than the sediment beds, as the beds would have had to be around before the dyke could have intruded.
