The first data (spatial and temporal associations, etc.) suggest a genetic relation to a heterogeneous source, with contamination, by crustal materials and other processes, of mantelic arc magmasspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/PlutonismMetamorphismLower PaleozoicPampean RangesLos Llanos batholithjournal articleopen access
