| 英文摘要 | Granulite is one of the main components of the lower crust electrical conductivity of granulite under the condition of lower crust is important to map the distribution of electrical conductivity in the lower crust the impedance spectra of granulite were determined using alternating current at 1 0 gpa and 373 similar to 1002 k in this study the experimental results were also analyzed in terms of the impedance spectra the results confirmed that the complex impedance depends on the frequency of alternating current the real and imaginary part of complex impedance decreased with increasing temperature the experimental results also indicated that the electrical conductivity shows the arrhenius behavior perfectly in the given temperature range the activation enthalpy derived is 0 31 ev at temperatures of 373 similar to 663 k, which indicated that electrical conductivity is dominated by the impurity in contrast, the activation enthalpy is 0 67 ev between 673 k and 1002 k corresponding to the conduction mechanism of electron-hopping between fe2+ and fe3+ we compared experimental results with the models derived from the mt data of ebian-mabian region in southwestern china and yingxian-shanghe region in northern china,and found that the electrical conductivity values obtained in this study are consistent with mt data |
