Abstract (in english)
   ourmaline is an ideal monitor of the local B flux in metamorphic systems because it is typically the sole borosilicate mineral found in metamorphic rocks and it can form throughout a metamorphic event. In addition, it can serve as a local B reservoir, as a sink or source. Because tourmaline is generally found as a trace or minor mineral dispersed throughout most metamorphic rocks, it can act as a relatively passive monitor of change in the metamorphic rock without having a significant influence on the effective bulk composition. However, tourmaline is major constituent (15%) in tourmalinites and, in this case, has a controlling influence on local mineral reactions. Tourmalines from metamorphosed granites and pegmatites exhibit compositional similarities to the tourmalines developed during crystallization of igneous rocks.
   Tourmaline, developed as a consequence of infiltration of B-bearing hydrothermal fluids, can have a wide range of compositions that are a function of the compositions of the altering host rock and the invasive fluid
