LE MAGMATISME DU CHAMP DU FEU (VOSGES SEPTENTRIONALES). Caractérisation et signification géodynamique
The late Devonian to early Carboniferous Champ du Feu Massif (Northern
 Vosges) exhibits a suite of plutonic rocks whose compositions range from gabbro-diorite to
 granite. The relationships between acid and basic rocks, show strong evidences of simultaneous
 emplacement of the two magmas without mixing. Geochemical features are typically calcalkaline.
 These characteristics, associated with those of the orogenic volcanism of the Bruche
 and Rabodeau massifs, suggest the genesis of the magmas to be related to the southward
 subduction of the Rheno-Hercynian ocean. A post-collisional setting is however not to be
 excluded. These two possibilities are discussed in the light of chronological and paleomagnetic
 data.
