Abstract
The investigation of irradiation sensitivity of electron spin resonance (ESR) centers is a significant part of the study of ESR signal characteristics and helps to gain insight into the physical mechanisms of paramagnetic centers. In this study, we have observed and compared the irradiation sensitivity characteristics of ESR centers under high-temperature baking in natural conditions by lava flow. Results show that the irradiation sensitivity of the Al and Ti–Li centers increases with the baking temperature, while the irradiation sensitivity of the Ti–H center increases first (up to ∼500 °C) and then decreases with temperature. Moreover, the ESR intensity of the Ti center is more strongly dependent on the annealing history of the samples than the Al center. In addition, from the results of the heating experiment, after heating above 1000 °C, additional irradiation does not produce new Ti–H signals, which probably indicates that the paleo-temperature of the lava flow in Yujiazhai area did not exceed 1000 °C.
