What is Radiocarbon Dating

Absolute dating
  1. Funding to support the advancement of the chemical sciences through research projects.
  2. Either non-carbon dating, if that's what you mean, or nothing.
  3. Recognizing and celebrating excellence in chemistry and celebrate your achievements.

Do you mean carbon dating? It is possible, though, to use carbon dating if there are remnants of organic matter that was trapped under a lava flow. Carbon dating is one type of radiometric dating, there are others. So the bottom line, naive answer to your question is another question - how many coins were once alive? Radiocarbon dating was the first method that allowed archaeologists to place what they found in chronological order without the need for written records or coins.

Radiocarbon Dating - American Chemical Society

Known as radiocarbon dating, this method provides objective age estimates for carbon-based objects that originated from living organisms.

  • Most, if not all, organic compounds can be dated.
  • The rate of decay of carbon is known so this can be used to estimate the age of the organism.
