A relative chronology of magmatic events was established based on field work and drill core relationships
Representative metasomatized bulk rock samples were selected and analyzed for trace elements and Sm–Nd isotopes
Based on these results it was shown that Montviel was emplaced via 4 distinct mantle pulses of volatile-saturated magmas
It was found that each of these injections evolved by fractional crystallization, the mixing of mantle and crustal fluids, and metasomatism.
