Radiocarbon dating uses the biological assumption that all living things absorb carbon, both ordinary carbon, C12, and radioactive carbon, C14, into their living tissue.At the moment of death the C14 begins to decay at a rate that scientists already know from other experiments.Lithic items cannot be dated by C14 radiocarbon methods but the same principle can be used using radioactive uranium.Rocks, when formed by volcanic reaction or other cataclysmic event, contain a minute quantity of radioactive substance. From the day of the rock's creation this radioactivity begins to deplete. Like C14, by measuring the loss, a scientist can attribute an age according to known loss rates. I would like to know how to determine the age for a piece of gold (archaeology gold piece) where and how much is the cost I mean if I could get a resultsomething similar to the carbono 14 dating test.

— Using the largest set of radiocarbon dates ever obtained from a single Maya site, a team of archaeologists have developed a high-precision chronology that sheds new light on patterns leading up to ...

This term means that older artefacts are usually found below younger items.

When an archaeological site is excavated the sides of the unexcavated baulk reveals layering of subsequent settlements and activity.

Limits to relative dating are that it cannot provide an accurate year or a specific date of use.

The style of the artefact and its archaeology location stratigraphically are required to arrive at a relative date.
