Dating corals

As 14C decays, the ratio of 14C to 12C changes over time. This change allows us to measure age.

How can we date corals? | Earth Observatory of Singapore

The difference between the two is the age since it was formed. But with deep-sea corals, that difference is both the age since the coral was formed and the age of the water in which it grew. Since we want to know both of these values, we face the classic problem of having one measurement and two unknowns. In such cases, you need to somehow determine one of those unknowns from another angle.

In the case of the deep-sea corals, we get their age by analyzing another element they contain: Offshore sumatra, you will use radiometric dating. When radiocarbon or 14c is the age of precision i. Radiocarbon dating in radiocarbon dating, marine organisms.
