Theoretical Modeling of Dielectric Properties of Artificial Shales

Figure 1

A scanning electron microscopy (SEM) image showing the mineral composition and microstructure of a typical shale sample (courtesy of C. Delle Piane). In this sample, the quartz (qz), calcite (cc), and pyrite (Pyr) grains are randomly distributed while the illite (Ill) shows some local disorder or misalignment, with respect to the vertical symmetry axis.
