“…Figure 2 shows that the E' intensities (no treat ment) correlate with the ages of samples, con firming the previous results (Odom and Rink, 1989;Rink and Odom, 1991). The relative numbers of oxygen vacancies measured as E' in tensities are also listed in Table 1 and plotted in Fig.…”

“…Recently, Odom and Rink (1989) reported that the intensities of E' centers and peroxy centers in granitic quartz are correlated with the radiometric ages of the samples in the time range of 0.1-1400 Ma. They suggested that these centers in granitic quartz can be used as geochronometer of the above age range, far beyond the limitation previously considered.…”

“…A correlation between the natural intensities of the E 1 ' center in granitic quartz and the ages of the host rocks was seen, (Shimoyama, 1986;Odom and Rink, 1989), however, the hydrothermal quartz did not exhibit such a correlation. This result implied that the ESR dating of Fig.…”

Quartz is one of the minerals useful for electron spin resonance (ESR) dating. The E 1 ' center is one of well-known paramagnetic defects in crystalline quartz. This center has a unique feature; its intensity increases on heating. An electronic process to explain this increase was found to be controlled not only by the number of oxygen vacancies, which are the precursors, but also by the number of Al hole centers, which depend on the previous radiation dose and on the Al concentration. The maximum intensity on heating is called the heat treated E 1 ' center, which has been posited to correspond to the number of oxygen vacancies in quartz and was found to be correlated with the ages of the host granites (Toyoda and Hattori, 2000). The experimental results on spin-spin relaxation times of the E 1 ' center indicate that external beta and gamma rays create oxygen vacancies in natural quartz rather than alpha or alpha recoil particles (Toyoda et al., 2005). The correlation between the numbers of the oxygen vacancies in quartz and the ages of the host granite made it possible to distinguish the quartz of a sedimentary reservoir from another with different age of crystallization (Toyoda and Naruse, 2002). Quartz fractions extracted from leoss and atmospheric deposition in Japan and from sediments in Japan sea were analyzed by ESR. The temporal change of the contributions from two dust sources in China were discussed in the context of climate change.

“…4 and 5, it can be concluded that the peroxy center and the E1 center are definitely overlapping with the aluminum center signal, as other researchers have shown (Stapelbroek et al, 1979;Odom and Rink, 1989;Ikeya, 1993). The position of the peroxy center covers peaks from 7 to 9, while the position of the E1 center covers peaks from 10 to 12, but only to a small extent under 5 mW of microwave power.…”
