Abstract: Refractive-index (RI) data are used to model gravity (g, gals) levels displayed by powdered-rock fragments. The base g level at each of two laboratories, were regressed with case (and other) weighting of 696 cases; representing all but two (2) of the 698, in which a total of 76,798 fragment RIs were compared to those of immersion liquids.
