Average life of oxygen vacancies of quartz in sediments is estimated by using the ESR(electron spin resonance) signals of E’ centers from the thermal activation technique. The experi-mental results show that the second-order kinetics equation is more applicable to the life estima-tion compared with the first order equation. The average life of oxygen vacancies of quartz from4895 to 4908 deep sediments in the Tarim Basin is about 10~(18) a at 27℃.
