IntroductionThe regional zoning of granitic pegmatite types iswell established and there is a general scheme ofspatial variation in relation with the parental granites(Heinrich 1953, Černý 1992). However, in some cases,there occur local variations that deviate from theordinary. Oyarzábal et al. (2009) described the regionalzoning of the Totoral Pegmatite Field (TPD) in thesouthern part of the Eastern Pampean ranges of SanLuis and demonstrated the parental relationshipsbetween leucogranites and pegmatites. Thiscontribution explores the possible interpretation of theanomalies in the regional distribution of thepegmatites, and their links with granites and tungstenbearingaplites.
