Does anyone know how Tests with electron spin resonance have proved that heat treatment of flint tools was present in the French Paleolithic culture about 19 000 years ago. Or how the use of the scanning electron microscopes has allowed archaelogists to perform accurate microwear studies on artifacts to determine the purpuse for which some tools were used?
Well, it helps if you know what electron-spin resonance and scanning electron microscopes are.
First off, they are not carbon dating. Please don't repeat that these things are carbon dating.
ESR essentially tells you when an object was last heated past a particular temperature. 500 degree heat, for instance, doesn't happen on its own very often to pieces of flint, but it happens routinely in fires, perhaps fires in which flint was heat treated.
Scanning electron microscopes allow the viewing of objects at very high magnifications, much higher than with traditional microscopes. So with a tool like that it is easier to see microwear, and so it is easier to study it.
It's about that simple.
