Electron spin resonance is a trapped charge dating method primarily used to date:
A) bone organic matter.
B) tooth enamel.
C) volcanic ash.
D) the last time sediments were exposed to light.

Question

Quizplus · Accepted Answer

Electron spin resonance (ESR) dating is primarily used to date tooth enamel, as well as other materials like bones and carbonate crystals, but it is most effective and commonly applied to tooth enamel. This method measures the trapped charge within defects in the crystal lattice of materials, which accumulates over time due to natural radiation. Tooth enamel is particularly suitable for this method due to its high density and the stability of the trapped charges it contains.
