At first, there were not many methods of dating were available, but now with advancement in the technology, we mainly have two types of the techniques to ascertain ages of ancient belongings.

Chart of a few different isotope half lifes: In reality, geologists tend to mix and match relative and absolute age dates to piece together a geologic history.

If a rock has been partially melted, or otherwise metamorphosed, that causes complications for radiometric (absolute) age dating as well.

Look for “absolute” ages such as cornerstones, dates carved into fresh concrete, or dates stamped on manhole covers.
