Three types of subvertical pegmatitic leucogranites and pegmatites populate the Red Cross Lake pegmatite field, located in a greenstone belt of the Sachigo Subprovince, Manitoba, in the northwestern part of the Archean Superior Province of the Canadi

The Gladstone-Dale relation' gives the index of refraction of light through a material as a sum of the optical properties of its oxide components. However, the calculated optical properties of ionic solids are only approximated from the composition,

Une incertitude dans la formule structurale d'un grenat peut resulter d'une analyse chimique incomplete ou erronee, d'une indetermination de la valence, et d'une distribution incertaine des elements parmi les sites cristallographiques. Toutefois, il

Une analyse optique repose sur des mesures de l'indice de refraction (n) et de la densite (D) afin de mieux delimiter la formule structurale, et ainsi fournir une verification independante de la composition. En termes physiques, une lumiere ayant une
