Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself. Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer.
How do you date stone artifacts?
There is no way to date a stone carving or artifact based on just the stone itself, because the chemistry of the situation is too variable and too complex. For example, moisture and temperature fluctuation will have a big effect on how a stone weathers.
This is often the layers of sediment surround the tool. Dating can be done by radiocarbon dating or other techniques which look at the amounts of elements like iron or potassium. It is the assumed that the tool is approximately as old as the rock which surrounds it.
How is Stone age calculated?
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
