The use of the E′ signal in flint for ESR dating

The E′ signal in silica has been used to date quartz in geological applications. However, the behavior of this signal in flint is quite different. Resetting the signal by heating is difficult, and the signal intensity saturates both with respect to artificial dose and to microwave power. Nonetheless, ages determined for flints from north-western Florida are in reasonable agreement with C-14 ages, suggesting that the method should be studied further.
