Views of Rock Physics in a Ternary Space

C-10 VIEWS OF ROCK PHYSICS IN A TERNARY SPACE Summary 1 Elastic properties of rocks can be made easier to understand and to compare among models when viewed in a three-dimensional “ternary space” with parameters plotted above a ternary diagram that represents the composition of a rock. Vagaries of certain models and differences or similarities among models that are difficult to explain when viewed in the conventional two-dimensional framework suddenly appear intuitive and straightforward. The ternary space model can be extended to additional dimensions although then it is difficult to visualize. In any number of dimensions the model can be
