Question: How old can carbon dating samples be used?

C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally make accurate analysis of older samples possible.

For what age of samples can carbon-14 dating BE USED?

500 to 50,000 years old The carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.

Can you carbon date gold?

As gold cannot be dated directly using the radiocarbon dating technique, which is a radio- metric method that uses the naturally occurring radioisotope carbon-14 (C14) to determine the age of carbonaceous materials up to about 60 000 years old, scientists used the organic fibres entwined within the helix-shaped gold
