(color online) Nyquist diagram of impedance spectra for [001] crystallographic K-feldspar at frequencies from 10−1 Hz to 106 Hz (from right to left), obtained at 2.0 GPa and 873 K–1223 K. and are the real and imaginary parts of the complex impedance, respectively. An equivalent circuit composed of the series combination of –CPES and –CPEE is selected to model the complex impedance semicircles.
