| Résumé | 126 samples from the granitic formations of the Massif of Champ-du-Feu, which were previouslydescribed by Von Eller, are wholly studied according to a chemico-mineralogical point of view.The major elements were dosed by the ARL Quantometer. The graphical representation (De LaRoche's diagramms) emphasizes very little variations together with their tendencies. In each case,the chemical indications are connected with the mineralogical characters of the sample and arecontrolled petrographically.This results in the identification of new granitic entities, as well as of geochemical or mineralogicaltendencies giving way to more accurate petrogenetic reasonings on the transition fromgranodiorites toward granites. Thus, new granitic formations and series are pointed out, theoccurence of which was not proved up-to-now.Moreover, the Massif of Champ-du-Feu divides into two great unities whith very sissimilar geochemical characteristics |
