The high-field-strength element(W, Zr, Nb, Ta, Ti, Sn, Hf, Th, U) oxides from granitic pegmatites concentrate thespecial interest of industry and scientist for their use as high-techcommodities and recorders of pegmatite evolution. However, the studies areheavily concentrated in most evolved granitic pegmatites of LCT geochemical signatureor in comparative analyses of their geochemical fingerprints and evolution. Inthis paper we describe an assemblage of tantalite-(Mn), tantalian rutile andpyrochlore-supergroup minerals that occurs in a rare-element granitic pegmatiteof beryl-columbite-phosphate subtype in the Sierras Pampeanas, Argentina.
