The Law of Cross-Cutting Relationships would be used here. If a fault cuts across a rock unit, it is younger than that rock unit. If a fault cuts across a series of rocks, but suddenly stops at a rock unit, then that rock unit which the fault stops at is younger than the fault. So let's say the order of rocks (from top to bottom), is A B C D. If the fault cuts across B C and D, but not A, then the age of the fault is sometime between A and B. If you know the absolute ages of A and B (let's say, rock A is 100 million years old and rock B is 200 million years old), then the age of the faulting is between 100 and 200 million years ago.
The age of rocks can be determined by radioactive dating.
Geologists determine absolute age of rocks by using radioactive dating.
Carbon14 dating (isotopic dating)
First step would be relative-dating: examining the new unit in the context of known rocks above and below it. Then look for correlative formations & fossils elsewhere.
Good question: Geologist use these methods to determine the ages of rocks. The absolute age of the rock and relative age of the rock. Now because the mid ocean ridges are place of divergent where plates move apart, the rock farther away from the ridges are older than the younger ones that are just form close to the ride. This is called relative dating. The absolute dating use Isotopes and radiometric dating meaning they have to have a hand sample to determine this. But I think the best method here for situation like this is the Relative ages of the rocks.

It helps determine the absolute ages of rocks
Geologists determine absolute age of rocks by using radioactive dating.
Carbon14 dating (isotopic dating)
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
They are able to tell the order in which events occured, NOT how long ago they occured.Identify the order in whicih rock units formed(:rocks makes babys with apenis

By the law of superposition: Oldest at the bottom and youngest at the top.
Relative age is used to determine the age and how old a geological feature or fossil.

Relative dating helps us to determine the sequential order in which a series of events occurred. It can't tell us WHEN those events occurred, but it allows us to create a basic order of events.
