Which of the following is the relatively most accurate method for dating of fossils?
  1. radio-carbon method
  2. potassium-argon method
  3. electron-spin resonance method
  4. uranium-lead method.

Solution

Electron spin resonance method is relatively most accurate method for dating fossils.
Electron spin resonance dating is a technique that can directly detect unpaired or odd electrons in atomic or molecular systems. In this technique, a static magnetic field and microwaves are used to observe the behavior of the unpaired electrons in the material being studied. The study of the behavior of the electrons in a sample gives information about the condition of the sample.
