Abstract

Calculating the discriminant factors using oxide concentrations in 918 corundum crystals of the main primary types deposits allows us to propose for the first time a statistical classification which determines the most probable deposit-type for secondary placer corundum deposits. The classification by discriminant analysis is applied to corundum associated with the basaltic placer deposits of Madagascar (from the Northern, Central and Eastern regions) as well as the primary Rockland mine ruby deposit (ex-John Saul mine) in Kenya.
