Although both relative and absolute dating methods are used to estimate the age of historical remains, the results produced by both these techniques for the same sample may be ambiguous. Which ones can be used for relative dating and which ones can be used for absolute dating? One of the most widely used and well-known absolute dating techniques is carbon or radiocarbon dating, which is used to date organic remains.
Relative Vs. Absolute Dating The Ultimate Face-off
