Forty-seven samples from the middle Pennsylvanian Breathitt Formation were examined petrographically to determine which shale attributes most directly influence slake durability. The study combined thin section examination with x-ray diffraction analyses of clay mineral orientation and clay mineralogy. Slake durability indices were obtained using a 60-min, one-cycle test and oven-dried samples. Multiple-linear regression indicates a high degree of correlation between slake durability indices and two measured shale characteristics, clay percent and clay mineral orientation. A discriminant function, using these two characteristics, proved successful in differentiating slakable from durable shales, correctly classifying 37 of the 47 tested samples.
