What is the difference between radiocarbon dating and carbon 14 dating?

Radiocarbon dating uses carbon isotopes. Radiocarbon dating relies on the carbon isotopes carbon-14 and carbon-12. Scientists are looking for the ratio of those two isotopes in a sample. Carbon-14 is an unstable isotope of carbon that will eventually decay at a known rate to become carbon-12.

What is luminescence geology?

Hence, both in geology and archaeology, the luminescence age simply connotes time that has passed since the occurrence of a specific energy zeroing event. In geology, this might be a geomorphic event that exposed sediment to sunlight. Zeroing by sunlight is also sometimes referred to as optical bleaching [3].
