    The Transition Between the Scale Domains of Ray and Effective Medium Theory and Anisotropy: Numerical Models

    The anisotropy of a periodically layered isotropic medium is numerically modeled in order to study the effect of the scale of heterogeneity on seismic observations. An important motivation is to delineate the ...

    Elastic Anisotropy of a Metamorphic Rock Sample of the Canadian Shield in Northeastern Alberta

    The presence of fractures and textures cause metamorphic rock masses to be seismically anisotropic. Neglect of this anisotropy in the processing of field seismic data causes problems in the final reflection im...

    Initial seismic observations from a deep borehole drilled into the Canadian Shield in northeast Alberta

    The availability of a deep borehole in northeastern Alberta provides an unprecedented opportunity to study the in situ metamorphic craton rocks. This borehole reaches a depth of 2.4 km, with 1.8 km in the cry...

    Effective Stress Coefficient for Seismic Velocities in Carbonate Rocks: Effects of Pore Characteristics and Fluid Types

    The concept of effective stress is key for understanding the dependence of rock elastic and compaction behaviors on stress and pore-fluid pressure. Previous studies on the concept largely used data acquired on...

    Correction to: Effective Stress Coefficient for Seismic Velocities in Carbonate Rocks: Effects of Pore Characteristics and Fluid Types

    Due to an unfortunate oversight the sentence “Also, the fact that some carbonates, such as siliciclastic rocks, may be less sensitive to compaction adds another level of complexity.” is not given correctly.
