Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Many people think that radiometric dating has proved the Earth is millions of years old. September 15, When news is announced on the discovery of an archaeological find, we often hear about how the age of the sample was determined using radiocarbon dating, otherwise simply known as carbon dating.

Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials.
It is an accurate way to date specific geologic events. Since the early twentieth century scientists have found ways to accurately measure geological time. Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. Sincescientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain. Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.
