If you can get an absolute age using absolute dating why is relative dating useful? What is the difference between relative and absolute dating? International Journal of Chemical Kinetics.
Example where the rate of finding the absolute dating. Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type. In archaeology and geology, the process of determining the approximate numerical age of something is called Absolute Dating. In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.
Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes. If sufficient sedimentary material is available, it will be deposited up to the limits of the sedimentary basin. Nevertheless, they can provide an abundance of useful information. Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques. There is a huge difference between talking and dating.
