Electrical Conductivity of Amphibole Eclogite at 1.0 GPa
摘要
Abstract
We measured the electrical impedance spectra of two amphibole eclogite samples collected from Shangnan county of Shanxi province at 1.0 GPa within the frequency range of 10 -1-10 6 Hz.The results indicate that the complex impedance depends on the frequency and temperature.At a given temperature,the modulus of complex impedance decreases with the increasing frequency,and the phase angle first decreases and then increases with the increasing frequency.At a given frequency,the modulus decreases with the increasing temperature and the phase angle increases with the increasing temperature.The range of electrical conductivity value of amphibole eclogite is 10 -6-1 S/m,and the relationship between conductivity and temperature can be fitted by Arrhenius relation.The activation enthalpies derived are 33-58 kJ/mol at low temperature and 108-163 kJ/mol at high temperature, respectively.The conduction mechanism of amphibole eclogite is likely related to the electron hopping between Fe2+ and Fe3+ .关键词
