AB: Over the past several years, huge amounts of data related to structural, electronic and mechanical properties of minerals have been produced by numerous experiments and calculations. This trend of rapid increase in mineral datasets will continue in the coming years. It has now been possible to perform atomistic simulations for mineral systems containing several millions or a few billions of atoms using semi-empirical molecular dynamics approach. Also feasible are quantum mechanical simulations of systems involving several hundreds of atoms. All these high-end computations are producing massive datasets, which are multivariate and time-dependent. Gaining insight into such datasets is, however, a non-trivial task. Recently, we have initiated to adopt a visualization approach to facilitate understanding of various data related to geophysically relevant minerals such as silicates and oxides. In this talk, I will present our current progress in this endeavor by considering two visualization case studies. In the first case, we are visualizing multivariate elastic moduli and anisotropic wave propagation as a function of composition, pressure and temperature. In the second case, we are visualizing defect-induced properties in minerals.
