Resumen:
Chemical analyses of tourmalines were made of pegmatites, metamorphic rocks of theConlara Metamorphic Complex and from Los Alanices granite. Tourmalines are aluminousand belong to the schorl-dravite series. Analysed crystals of three pegmatites havecompositional zonation with rims enriched in Ti, Mg and Ca, and depleted in Al, related tocores. Results were compared with analyses of tourmalines from previous works and it wasfound that belong to the same series.
