K₁c Values that are environment – sensitive were obtained. Flow and fracture resulting from Vickers indentation testing of {100} have been studied. Plastic flow occurred in calcite; they are anisotropic and environment - sensitive. Fracture in calcite occurred in lateral, median, and subsurface models. Meyer’s indices were determined and they also are environment – sensitive, they were found to be n < 2.
