Resumen de Características de las turmalinas asociadas a rocas pegmatíticas del área de la Fregeneda, Salamanca (España)
Encarnación Roda Robles, Alfonso Pesquera Pérez, Francisco Velasco Roldán
In the NW part of the province of Salamanca (Spain) many pegmatites occur. Some of them correspond to Li-bearing pegmatites, but other pegmatitic types are also important. In this paper tourmalines from some of this pegmatitic bodies and their tourmalinized host-rock are examined in terms of their chemistry and conditions of formation. According to their chemistry, they belong to the schorl-dravite series. Substitutions towards alkali-free or proton deficient members are observed. The chemical variations between the studied tourmalines could indicate a different origin for their associate rocks.
