Resumen:
The origin of accessory minerals in granitic pegmatites, especially those that concentrate high-field-strength elements (W, Zr, Nb, Ta, Ti, Sn, Hf, Th, U), is occasionally multi-episodic under variable physico-chemical conditions.  In this paper we describe an assemblage of ?ixiolite?, tantalian rutile, wodginite-group and columbite-group minerals, cassiterite and pyrochlore-supergroup minerals that occurs in a rare-element granitic pegmatite of the beryl-columbite-phosphate subtype in the Eastern Pampean Ranges, Argentina.
