Practical limit of radiocarbon dating

But there are other ways in which a rock can become exposed, as for example when a glacier erodes the sediment covering bedrock: when the glacier melts, the bedrock will be exposed.

In the article on radiocarbon dating we have already introduced one cosmogenic isotope, Si and which has a half-life of 717,000 years.

In the following article, some of the most common misunderstandings regarding radiocarbon dating are addressed, and corrective, up-to-date scientific creationist thought is provided where appropriate. Radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth.

Radiocarbon is not used to date the age of rocks or to determine the age of the earth.

Because the isotopes we're using have a short half-life, it follows that if a rock has been buried for a few million years the quantities of these isotopes will be negligible.

Our approach was tested on known-age samples dating back to 40,000 BP, and served as proof of concept.Other radiometric dating methods such as potassium-argon or rubidium-strontium are used for such purposes by those who believe that the earth is billions of years old.
