A value named for this man is proportional to the ratio of the sum of the radii of the A-cation, B-cation, and anion, and is greater than one for hexagonal structures; that value is his namesake tolerance factor.

A value named for this man is proportional to the ratio of the sum of the radii of the A-cation, B-cation, and anion, and is greater than one for hexagonal structures; that value is his namesake tolerance factor. One rule derived by this man can be applied to 3-component compatibility diagrams. This man's study of contact metamorphism in hornfels in Kristiania led to his derivation of the rule that for a rock at equilibrium, the number of (*) phases is equal to or less than the number of components; that is his version of Gibbs' phase rule. One scheme developed by this man divided species into atmophile, lithophile, siderophile, and chalcophile. For 10 points, name this Russian mineralogist and namesake of a mineralogical formula and a classification system, the father of geochemistry.
