How is electron spin resonance used for absolute dating?

Introduction Electron spin resonance (ESR) has been used for absolute dating of archaeological materials such as quartz, flints, carbonate crystals, and fossil remains for nearly 50 years. The technique is based on the fact that certain crystal behaves as natural dosimeters.

What is electron spin resonance (ESR)?

Introduction. Electron spin resonance (ESR) has been used for absolute dating of archaeological materials such as quartz, flints, carbonate crystals, and fossil remains for nearly 50 years. The technique is based on the fact that certain crystal behaves as natural dosimeters. This means that electrons and holes are accumulated over time in...

How do you find the age of an electron spin resonance?

The electron spin resonance age of a substance is found from the following equation: where D E is the equivalent dose, or paleodose (in Gray or Gy), i.e. the amount of radiation a sample has received during the time elapsed between the zeroing of the ESR clock (t = 0) and the sampling (t = T).

What is ESR dating used for in geology?

Electron spin resonance dating is being used in fields like radiation chemistry, biochemistry, and as well as geology, archaeology, and anthropology. ESR dating is used instead of radiocarbon dating because ESR dating can date newly formed materials or previously heated rock.

Can ESR dating be applied to fossil remains?

Since, ESR dating is best and most commonly applied to tooth enamel in archaeology, this paper predominantly focuses on its direct application to fossil remains. In solid-state physics, trapped electrons and holes can be represented with...

What is ESR dating and why is it important?

ESR dating has contributed to understanding the origins of hominin species, overlap (or lack of same) between Neanderthals and modern humans, and the expansion of hominids from Africa all the way to the Western Hemisphere.
