TL;DR: The one-dimensional form of Skempton's B equation is inadequate to describe the behavior of cohesionless materials with pore fluids that contain large quantities of free and dissolved gas.

TL;DR: In this paper, an analysis of 83 specimens of the basal McMurray Formation clay shales (basal clays) has revealed a novel clay mineralogical suite: the clays are illite-kaolinite clays, but vermiculite and mixed-layer clays were present in significant amounts.
Abstract: Analysis of 83 specimens of the basal McMurray Formation clay shales (basal clays) has revealed a novel clay mineralogical suite: the clays are illite–kaolinite clays, but vermiculite and mixed-layer clays are present in significant amounts. Index and engineering behavior are affected: high compressibilities, low residual angles of shearing resistance, and low permeabilities are characteristic; index properties, however, are typical of illite–kaolinite clays.Comparison of outcrop and borehole data reveal significant differences between the sample sources.The location of the basal clays at the base of future open pits has implications for oil-sand development with respect to highwall stability and tailings disposal structures.
